FEASIBILITY EVALUATION FELICITA CREEK CHATHAM SITE ESCONDIDO, CALIFORNIA
EXECUTIVE SUMMARY
This Feasibility Evaluation has been prepared by Hargis + Associates, Inc., on behalf of the Chatham Site Potentially Responsible Parties (PRP) Group (the Group) for the Chatham Site1 located at 2257 Bernardo Avenue, Escondido, California (Figure ES-1). The Group continues to successfully implement the selected groundwater remedy described in the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC)-approved Remedial Action Plan in accordance with the Consent Decree (CD) between the DTSC and the Group entered by the federal district court on February 5, 1999. Per the CD, Remedy Review Reports (RRR) are submitted to DTSC every 5-years with the most recent RRR originally being submitted on June 29, 2010. Revised versions of the RRR, which addressed agency comments, were submitted to DTSC on September 29, 2011 and August 24, 2012. Conditional approval of the RRR was provided by DTSC in a letter dated March 26, 2013, in which one of the conditions of approval was to further evaluate site related contaminants detected in Felicita Creek. With this understanding, this Feasibility Evaluation assesses remedial alternatives to manage flow of site related contaminants in groundwater to Felicita Creek.
The Site is within the Felicita Hydrologic Subarea (HSA), a south-sloping elongate basin drained by Felicita Creek. The upper reaches of Felicita Creek, including the West and East Forks are located within the site area and converge in the northern portion of Felicita Creek (Figure ES-2). 1
The “Site” shall include the areal extent of any known or suspected release or threatened release of a hazardous substance, pollutant, or contaminant originating at the Yard (as defined herein). The Site includes but is not limited to a 5-acre portion of real property commonly known as the Chatham Brothers Barrel Yard located at 2257 Bernardo Avenue (hereinafter referred to as the “Yard”), Escondido, California, which is part of a 35-acre parcel (the “Property”), as well as property located at 1261 Gamble Lane (the “Gamble Lane Property”), Escondido, California.

HARGIS + ASSOCIATES, INC.
EXECUTIVE SUMMARY (continued) The primary Site-related contaminants in groundwater and surface water at the Site consist of volatile organic compounds (VOCs). Both the Group and DTSC have conducted risk analyses of Felicita Creek and concluded that Site-related contaminants levels within Felicita Creek are protective of human health and the environment.
In the vicinity of the Yard, pumping of the groundwater remediation system extraction wells has created an effective capture zone, restricting contaminant migration downgradient. To the south of the Yard, VOCs dissolved in groundwater continue to dissipate through the physical process of natural attenuation (Figures ES-3 and ES-4).
Groundwater data suggest that the lower
volume, higher concentration VOC mass in the deep zone contributes to the VOC mass in the shallow zone through localized upward gradients primarily in Felicita County Park. Overall the rate of VOC mass contribution from deeper to shallow groundwater is constrained by the lower bulk hydraulic conductivity of the deep zone.
Surface water in Felicita Creek derives from two major sources: 1) overland flow and tributary streams following rainfall events, and 2) groundwater flow into the channel where the channel is incised to the water table (Figure ES-5). Site-related VOCs are not present in overland flow of surface water, so Site-related VOC contributions to Felicita Creek are from groundwater flow into the creek channel.
From just downstream of the Felicita Road culvert, groundwater
containing dissolved VOCs is intercepted by the Creek channel incised to below the water table (Figures ES-5 and ES-6).
Aside from VOCs, however, Felicita Creek is impaired with respect to its designated beneficial uses due to non-Site related constituents. Non-Site related inorganic water quality constituents were consistently detected in surface water samples collected in 2013 through 2015, and some exceeded Basin Plan water quality objectives for one or more surface water samples collected. In addition, Felicita Creek has been designated as an “impaired” water body under Section 303(d) of the Clean Water Act. Felicita Creek is on the 303(d) list since Felicita Creek fails to meet Basin Plan water quality objectives, due to adverse impacts by non-Site related pollutants, total dissolved solids, and aluminum.

EXECUTIVE SUMMARY (continued)
Potential remedial technologies and a screening of remedial technologies were presented and discussed in a technical meeting with DTSC, Regional Water Quality Control Board (RWQCB), and representatives of the Group on April 20, 2015. Based on the initial technical meeting, two additional technical meetings were held on August 19, 2015 with RWQCB, DTSC, United States Army Corps of Engineers, and representatives of the Group and on August 25, 2015 with RWQCB, County of San Diego, and representatives of the Group to discuss remedial technology implementability issues to assist in the development of the Feasibility Evaluation.
Remedial technologies were screened and the retained technologies were assembled into the following remedial alternatives: FC1: Current Monitoring and Contingency Plan; FC2: Ex situ surface water treatment within Felicita Creek via installation of structures; and FC3: Hydraulic containment (pump and treat with liquid phase granular activated carbon adsorption treatment) with three treated groundwater end use options – FC3A treated water to Felicita Creek, FC3B treated water to subsurface; and FC3C treated water as non-potable reuse.
Each remedial alternative was evaluated based on the following evaluation criteria: protection of human health and the environment; effectiveness; implementability; cost; and preservation of the water resource. The remedial alternatives were compared based on their respective performance in achieving the evaluation criteria (Table ES-1). The remedial alternatives are protective of human health and the environment. Based on this analysis, remedial alternatives FC-2 and FC-3 provide slight to moderate reduction of Site-related VOCs in Felicita Creek. It is equally clear remedial alternatives FC-2 and FC-3 are complex processes to implement and highly disruptive. FC-1 is the preferred alternative. It is protective of human health and the environment, it is implementable while the other alternatives may not be due to permitting limitation. FC-1 is least disruptive and preserves the water resource.

1.0 INTRODUCTION
This document has been prepared by Hargis + Associates, Inc. (H+A), on behalf of the Chatham Site Potentially Responsible Parties (PRP) Group (the Group) for the Chatham Site1 located at 2257 Bernardo Avenue, Escondido, California (the Site) (Figure 1).
The Group continues to
successfully implement the selected groundwater remedy described in the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC)-approved Remedial Action Plan (RAP) (DTSC, 1998) in accordance with the Consent Decree (CD) between the DTSC and the Group entered by the federal district court on February 5, 1999. In accordance with the CD, Remedy Review Reports (RRR) are submitted to DTSC every 5-years with the most recent RRR originally being submitted on June 29, 2010. Revised versions of the RRR, which addressed agency comments, were submitted to DTSC on September 29, 2011 and August 24, 2012. The primary purpose for the RRR is to demonstrate the effectiveness of the groundwater remedy. Conditional approval of the RRR was provided by DTSC in a letter dated March 26, 2013, in which one of the conditions of approval was to further evaluate site related contaminants detected in Felicita Creek.
With this understanding, this Feasibility Evaluation
assesses remedial alternatives to manage flow of site related contaminants in groundwater to Felicita Creek.

1.1 PURPOSE AND SCOPE
This Feasibility Evaluation assesses remedial alternatives to manage the flow of Site-related contaminants to Felicita Creek in response to a letter from the DTSC dated September 24, 2014, regarding the April 2014 Annual Monitoring Submittal and Conceptual Site Model (CSM) Update (H+A, 2014a; DTSC, 2014b).
More specifically, DTSC General Comment #3
recommends that “the PRP Group evaluate the contaminant fate and transport mechanisms and hydrogeology of site related contaminants discharging into Felicita Creek.
The evaluation
should address mechanisms which would significantly reduce or stop the flow of site related contaminants to the creek.” The evaluation of contaminant fate and transport mechanisms including groundwater flow in the vicinity of the Site and Felicita Creek were presented in previous documents including the most recent CSM Update (H+A, 2015b).
This Feasibility Evaluation presents the following:

Comparison of Remedial Alternatives
1.2 SITE BACKGROUND
The following sections summarize the general background and elements of the CSM that pertain to groundwater and surface water flow and quality in the vicinity of Felicita Creek.

1.2.1 Location and Creek History The Site is within the Felicita Hydrologic Subarea (HSA), a south-sloping elongate basin drained by Felicita Creek.
Granitic rock underlies the Felicita HSA, the bulk of it being fractured
bedrock, but the uppermost portion is gradually weathered to decomposed granitic rock at various depths.
The Chatham Yard is located near the upper reaches of both the West Fork and a branch of the East Fork of Felicita Creek. The East and West Forks converge in the northern portion of Felicita County Park (FCP) (Figure 2A).
The natural channels of Felicita Creek have been altered over time by the placement of culverts, allowing streets to cross the creek; by channelization in the upper stretch of the West Fork of the Creek west of Bernardo Avenue and portions of the upper East Fork west of Felicita Road; and by the placement of a small earth-fill dam on the East Fork of the creek at Felicita Road, as well as the placement of a series of stonework check-dams within FCP. The stonework dams were placed in the 1930s, and the earth-fill dam predates the 1950s.
1.2.2 Groundwater and Surface Water Flow Groundwater flows through fractures in bedrock at depth, and flows through the more porous decomposed bedrock nearer to land surface, under the influence of the regional hydraulic gradient (H+A, 1996). Groundwater data indicate that subsurface conditions, combined with topography and significant narrowing of the Valley to the south, results in convergence of groundwater flow toward the center of the basin formed by Felicita Creek (Figure 2A).
Surface water occurs primarily in the East and West Forks of Felicita Creek, as well as its main channel downstream of the confluence of the East and West Forks in FCP (Figures 2A and 2B). Groundwater appears to be the source of base flow to Felicita Creek in the northern portion of FCP, where flow becomes perennial in the East Fork of the Creek. Stretches of the West Fork of Felicita Creek appear to be perennial, but for much of the year the West Fork does not persist downstream as surface flow to the confluence with the East Fork. Several ephemeral streams are tributaries to Felicita Creek, flowing only when there is seasonal surface runoff (H+A, 1996).
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
Surface water flow is typically highest in March/April after the rainy season and is lowest in September/October during the dry season when the flow in Felicita Creek is principally base flow from groundwater.
1.2.3 Groundwater and Surface Water Monitoring Results Groundwater and surface water have been monitored for Site related contaminants and other non-Site related constituents and compounds.
1.2.3.1 Site-Related Contaminants The primary Site-related contaminants exceeding drinking water Maximum Contaminant Levels (MCLs) in groundwater and surface water at the Site consist of volatile organic compounds (VOCs). The lateral and vertical extent of VOC groundwater contamination is well defined based on the sampling of 60 key wells in the monitoring program, including shallow monitor wells, deep monitor wells, shallow and deep regional wells, and extraction wells.
From
groundwater VOC data collected over the last 20 years, the lateral and vertical extent of groundwater contamination is depicted as shallow and deep plumes, with changes tracked over time (Figures 3 and 4). Details of VOC distribution in groundwater have been provided as part of the groundwater monitoring program, most recently for October 2015 (H+A, 2015c). Within the geographical area addressed in this Feasibility Evaluation, specifically FCP, recent VOC analytical data have been summarized (Table 1).
An expanded surface water sampling program has been implemented on a semiannual basis from April 2013 through October 2015 (H+A, 2015c). Recent VOC analytical data for surface water have been summarized (Table 3). VOCs were not detected in surface water samples collected from West Fork sampling locations in April 2015 or October 2015. These results are consistent with historic analytical results of surface water samples collected by the Group from the West Fork of Felicita Creek. VOCs detected in surface water samples collected from the East Fork and main channel of Felicita Creek in October 2015 remained within historic ranges. Using trichloroethylene (TCE) as an indicator compound due to its prevalence, concentrations decrease downstream from the vicinity of surface water sampling location FC-4 until reaching
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
the vicinity of surface water sampling locations FC-7 and FC-8A, where the TCE concentrations were near or below the detection limit (Figure 5).
Results of historic and recent sampling confirm that surface water flow in Felicita Creek is fed by groundwater, and it is expected that surface water in Felicita Creek will respond over time to reductions in VOC concentrations in shallow groundwater as natural attenuation of the groundwater plume progresses near the creek (H+A, 2015b).
1.2.3.2 Non-Site Related Constituents and Compounds Inorganic water quality of shallow and deep groundwater was characterized as part of the Remedial Investigation (RI) (H+A, 1996). Initial sampling of monitor wells installed during the RI included analysis of inorganic constituents, including chloride, nitrate, sulfate, total dissolved solids (TDS), and selected metals. Based on sampling of upgradient and other wells outside the area of VOC impact to groundwater, the RI found that:
Chloride, sulfate, [TDS], and nitrate concentrations detected in the background wells exceeded federal and/or state Maximum Contaminant Levels (MCLs) . . .
Based on the similarity of the concentration range for chloride, sulfate, TDS, and nitrate between background wells and other wells, these compounds appear to be representative of regional conditions and are not related to historical operations conducted at the site. (H+A, 1996)
In May 2015, additional groundwater sampling was conducted using monitor wells located in the vicinity of Felicita Creek within FCP, in order to update and expand the characterization of inorganic water quality near the creek. Shallow monitor wells MW-53, MW-54 and MW-58, as well as deep monitor wells MW-66 and MW-70, were sampled on May 21, 2015 (Figures 3 and 4).
Groundwater samples were analyzed for common ions, TDS, surfactants, metals
including mercury and hexavalent chromium, chlorinated phenolics, pesticides, polychlorinated biphenyls, semi-volatile organic compounds, cyanide, hardness, sodium, and hydrogen sulfide. Most of these analytes were not detected (Appendix A). Concentrations of detected analytes have been provided, and compared with applicable regulatory standards for surface water
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
(Table 2). Concentrations of chloride, nitrate, sulfate and TDS were generally comparable to those in RI samples, and also exceeded regulatory levels, specifically Basin Plan Water Quality Objectives, in some or all sampled wells (Regional Water Quality Control Board [RWQCB], 2012). Other constituents exceeding regulatory standards in 2015 were iron, manganese, and total nitrogen, which exceeded instantaneous maximum effluent limitations under the San Diego National Pollutant Discharge Elimination System (NPDES) permit (Table 2).
Inorganic surface water quality was characterized as part of the RI (H+A, 1996). Analysis of surface water samples collected from surface water sampling location FC-4 in 1994 included analysis of general minerals and coliform bacteria. The RI found that:
Results of general mineral analyses indicate that surface water is a sodium-calcium-sulfate water type with a TDS content of 1,290 mg/l [milligrams per liter], which is consistent with general mineral data obtained from groundwater sampling of monitor wells in the vicinity of the site. (H+A, 1996)
The naturally-occurring inorganic water quality constituents TDS, chloride, sulfate, nitrate and turbidity were detected in surface water samples collected in October 2015 (Table 4). Concentrations of these constituents at surface water sampling location FC-4 were comparable to those detected in 1994 and, with the exception of nitrate, exceeded Basin Plan water quality objectives for one or both surface water samples collected in 2015 (RWQCB, 2012). These results indicate that Felicita Creek is impaired with respect to its designated beneficial uses due to naturally occurring, and therefore non-Site related, constituents.
Total coliform bacteria were detected in surface water samples collected at surface water sampling locations FC-4 and FC-10 in April 2015, at populations of 1,600 most probable number (MPN)/100 milliliters (ml) (Table 4). This exceeds the water quality standard of 200 MPN/100ml specified for fecal coliform bacteria, and was higher than the detection of 130 MPN/100ml at surface water sampling location FC-4 in 1994. Although the Basin Plan requires 5 sampling events for fecal coliform within 30 days to establish a reliable bacterial population (RWQCB, 2012), this result is consistent with previous sampling results and with the interpretation that Felicita Creek may be impaired with respect to its designated beneficial uses

due to high bacterial levels. The presence of coliform bacteria in Felicita Creek is a result of animal and human activity, and is not Site related.
1.2.4 Conceptual Site Model Summary As stated previously, the primary contaminants in groundwater at the Site consist of VOCs with the lateral and vertical extent being well defined based on the ongoing monitoring program. The following sections provide an overview of the CSM as it pertains to: groundwater to the north and in the vicinity of FCP; groundwater and surface water interaction in the vicinity of FCP; and Felicita Creek.
1.2.4.1 Groundwater to the North and Vicinity of Felicita County Park In the vicinity of the Yard, pumping of the groundwater remediation system (GRS) extraction wells has created an effective capture zone in this area, restricting contaminant migration downgradient. Since implementation of the remedy, concentration decreases to near or below detection limits in shallow monitor wells between the Yard and Cimarron Terrace demonstrate the separation of the shallow VOC plume (H+A, 2015b). Since implementation of the remedy, concentration decreases to near or below detection limits in deep monitor wells between the Yard and Hamilton Lane, as well as the order of magnitude decrease in VOC concentrations in axial deep monitor well MW-67, demonstrate the separation of the deep VOC plume by operation of the GRS for containment.
To the south of the Yard, downgradient of the capture zone, as groundwater with dissolved VOCs slowly migrates south, the VOCs continue to dissipate through physical processes of natural attenuation. South of Hamilton Lane, the shallow and deep plumes consist of low and generally decreasing concentrations of dissolved VOCs extending to the south end of FCP (Figures 3 and 4). Migration of the shallow and deep groundwater plumes is generally narrow and controlled by Site topography, geologic features, and groundwater flow. Groundwater data suggest that the lower volume, higher concentration VOC mass in the deep zone contributes to the VOC mass in the shallow zone through localized upward gradients primarily in the northern portion of FCP and the vicinity of monitor wells MW-54 and MW-70 in the southern portion of
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
FCP. But overall the rate of VOC mass contribution from deeper to shallow groundwater is constrained by the lower bulk hydraulic conductivity of the deep zone.
1.2.4.2 Groundwater and Surface Water Interaction in Vicinity of Felicita County Park In the vicinity of FCP, an evaluation of the water quality of Felicita Creek and its relationship to local groundwater has been provided (H+A, 2015a).
The results of this evaluation are
summarized as follows:
In the northern portion of FCP, Felicita Creek is a gaining stream.
Groundwater is the primary source of water to the stream, especially during the dry season.
The groundwater daylighting into the Felicita Creek channel moves through decomposed granitic rock rather than through discrete fractures in bedrock (Figure 6).
Understanding that this is a water table system in decomposed and fractured bedrock, it is likely that a proportion of groundwater flowing into the Felicita Creek channel is via upward vertical flow from the deep VOC plume, through decomposed granitic rock, between surface water sampling locations FC-11 and FC-10.
Between surface water sampling locations FC-10 and FC-7, TCE concentrations decline to below drinking water standards.
VOCs in surface water do not persist beyond the southern boundary of FCP, which is itself over a mile from the Creek’s outflow to Lake Hodges (Figures 3 through 5).
Surface water sampling in 2013 through 2015 was representative of low flow or base flow conditions.
From both groundwater and surface water data, it appears TCE concentrations detected in samples collected at and near surface water sampling location FC-4 are responsive to variations in local conditions, including the water table elevation, temperature, depth of water in the creek channel, and velocity of surface water flow.
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
An evaluation of water quality trends of groundwater and surface water in the vicinity of Felicita Creek has been provided with respect to VOCs (H+A, 2015a) (Figures 7 through 9). The Group has presented water quality data indicating that, as a result of the remedy at the Chatham Yard, the mass of the shallow VOC plume south of Hamilton Lane has decreased by approximately 90 percent (H+A, 2015b).
The shallow TCE plume continues to contract, and because
groundwater in this area is subject to an upward hydraulic gradient into Felicita Creek, future decreases in concentration in this area are anticipated to be reflected in nearby surface water sampling location FC-4 (Figure 7).
1.2.4.3 Felicita Creek Surface water in Felicita Creek derives from two major sources: 1) overland flow and tributary streams following rainfall events, and 2) groundwater flow into the channel where the channel is incised to the water table (Figure 6). Site-related VOCs are not present in overland flow of surface water, so Site-related VOC contributions to Felicita Creek are from groundwater flow into the creek channel. During parts of the year when overland flow contributes to the creek, any VOCs entering the channel via groundwater are mixed, reducing the detected concentrations of VOCs in surface water.
From just downstream of the Felicita Road culvert, groundwater containing dissolved VOCs is intercepted by the creek channel incised to below the water table (Figures 5 and 6). As water flows downstream from near surface water sampling location FC-11 to surface water sampling location FC-14, additional VOC-impacted water flows into the channel from shallow groundwater, with some flow from directly beneath the channel more representative of deep groundwater, while some proportion of VOCs volatilizes into the atmosphere. From surface water sampling location FC-14 to surface water sampling location FC-5, volatilization becomes a more dominant factor than groundwater flow into the creek, due in part to the boulders in the channel which force turbulent flow. From surface water sampling location FC-5 downstream to surface water sampling location FC-10, VOC-impacted groundwater flow into the channel dominates over volatilization, generally increasing concentrations.
As surface water flows
downstream of surface water sampling location FC-10, the factors contributing to volatilization
724_H01_2015-2_FE FC_txt.docx 12-21-15
9
HARGIS + ASSOCIATES, INC.
become relatively more dominant, and VOC concentrations decrease, ultimately to below detection limits as at surface water sampling locations FC-7 and FC-8A (Figure 5).
Aside from VOCs, however, Felicita Creek is impaired with respect to its designated beneficial uses due to naturally occurring, and therefore non-Site related, constituents (H+A, 1996 and 2015b). Non-Site related inorganic water quality constituents were consistently detected in surface water samples collected in 2013 through 2015 (Table 4), and some exceeded Basin Plan water quality objectives for one or more surface water samples collected. In addition, Felicita Creek has been designated as an “impaired” water body under Section 303(d) of the Clean Water Act (U.S. Environmental Protection Agency [EPA], 2011). Felicita Creek is on the 303(d) list since Felicita Creek fails to meet Basin Plan water quality objectives, due to adverse impacts by non-Site related pollutants, TDS and aluminum (EPA, 2011).
1.3 SUMMARY OF RISK ASSESSMENTS – HUMAN HEALTH AND ECOLOGICAL RISK
Both the Group and DTSC have conducted risk analyses of Felicita Creek and concluded that Site-related contaminant levels within Felicita Creek are protective of human health and the environment (H+A, 2012; DTSC, 2014a and 2014c).
As part of the original Human Health Risk Assessment and Screening Ecological Evaluation Report (Environ, 1996), surface water risk-based trigger levels (SWRBTLs) were developed for the Site. The original SWRBTLs values were evaluated and updated to reflect changes in risk assessment methodology and exposure factors and the updated values were provided in the most recent 5-Year Remedy Review Report (H+A, 2012) and again in the Monitoring and Contingency Plan (MCP) prepared in September 2014 (H+A, 2014b). In February 2015, DTSC requested updated hypothetical SWRBTLs be calculated to facilitate risk communication to the public.
In response to DTSC comments, the Group prepared hypothetical SWRBTLs for
Low-Frequency, High-Contact and High-Frequency, Low-Contact scenarios, presented below for prevalent compounds (Chatham PRP Group, 2015).

For the two hypothetical exposure assumptions evaluated (i.e., a low-frequency, high-contact scenario, and a high frequency, low-contact scenario), the actual concentrations of VOCs detected in Felicita Creek (Table 3) remain substantially below the calculated hypothetical risk communication values, confirming that the remedy is providing ongoing protection of public health (Chatham PRP Group, 2015). The Group is currently working with DTSC to finalize the SWRBTLs.
Environmental Health Decisions (EHD) reviewed surface water data as part of an ecological screening assessment (Appendix B of H+A, 2012). Site-related constituents did not exceed federal or state ecological screening values established by EPA, RWQCB, and the U.S. Department of Energy. EHD concluded that “there are no ecological screening levels exceeded and no ecological impacts from surface water conditions in Felicita Creek are anticipated.” In addition, DTSC requested the Ecological Risk Assessment Section (ERAS) review the Final 5-Year Remedy Review Report and associated documents to evaluate potential impact on Felicita Creek. The review concluded “Based on the data provided, ERAS does not find significant risk from the detected VOCs to ecological receptors from surface waters of Felicita Creek.” (DTSC, 2014a).
1.4 EVALUATION GOALS
Traditionally, either passive or active mechanisms are utilized to remedy VOCs.
Passive
remediation entails monitoring and natural attenuation along with an ongoing monitoring program to ensure protection of human health and the environment is maintained.
Active
remediation includes components of passive remediation coupled with on-going active remedial 724_H01_2015-2_FE FC_txt.docx 12-21-15
11
HARGIS + ASSOCIATES, INC.
technologies that reduce VOC concentrations in groundwater and/or surface water through enhanced volatilization, treatment and/or hydraulic containment.
The goal of this Feasibility Evaluation is to identify and evaluate potential remedial approaches that are protective of human health and the environment and may be able to “significantly reduce or stop the flow of Site-related contaminants” to Felicita Creek to the extent practical.
As described above, VOCs enter Felicita Creek as dissolved constituents of groundwater that enters the creek channel under the influence of the local hydraulic gradient.
Data trends
representing both groundwater and surface water indicate that passive remediation through monitoring and natural attenuation will be successful with time. Practically however, for active remediation, the range of potential alternatives is conceptually limited. The goal of reducing or stopping flow of Site-related contaminants to the creek could be addressed by active technologies that either:
treat VOCs in groundwater near the creek before the groundwater enters the creek channel;
stop or reduce the flow of groundwater containing VOCs to the creek channel, though this would likely result in dewatering a stretch of the creek; or
reduce VOC concentrations in creek surface water after groundwater enters the creek with active remediation that would accelerate the rate of reduction that already naturally occurs as the creek flows through FCP.
Each of these approaches presents its own challenges, as described in the following sections. It is likely that both passive and active remediation alternatives will operate for similar timeframes; therefore, the timeframe to complete is not evaluated in this Feasibility Evaluation.

2.0 REMEDIAL TECHNOLOGIES FOR FELICITA CREEK
In order to address the DTSC comment to provide an evaluation to “address mechanisms which would significantly reduce or stop the flow of site related contaminants to the creek,” remedial technologies are presented in the following sections to address the presence of VOCs in Felicita Creek from approximately surface water sampling location FC-11 to FC-10. As described in the preceding section, groundwater containing VOCs is intercepted by the Felicita Creek channel incised to below the water table. Mechanisms to reduce or stop the flow of VOCs to the creek should remove VOCs from groundwater prior to interception by the creek channel, remove impacted groundwater before it enters the creek channel, or remove VOCs from the creek surface water after groundwater enters the creek channel.
2.1 IDENTIFICATION AND SCREENING OF POTENTIAL TECHNOLOGIES
Potential remedial technologies demonstrated to be appropriate at sites with similar compounds of concern were identified as potentially applicable to the Site-specific conditions in the vicinity of Felicita Creek. Sources used to identify and evaluate the remedial technologies include literature review, vendor information, case studies, engineering judgment, and Site-specific data. Remedial technologies and a screening of remedial technologies were presented and discussed in a technical meeting with DTSC, RWQCB, and representatives of the Group on April 20, 2015. The screening results and technologies that were identified for further evaluation are discussed below. Based on the initial technical meeting, two additional technical meetings were held on August 19, 2015 with RWQCB, DTSC, U.S. Army Corps of Engineers (USACE), and representatives of the Group and on August 25, 2015 with RWQCB, County of San Diego, and representatives of the Group to discuss remedial technology implementability issues to assist in the development of the Feasibility Evaluation.

2.2 POTENTIAL TECHNOLOGIES DESCRIPTIONS
No Action No action is generally required to be evaluated during remedial technology screening, but the Group performs groundwater and surface water monitoring in accordance with the MCP (H+A, 2014b) as specified by the DTSC-approved RAP and Consent Decree. Therefore, the no-action alternative will not be considered in this Feasibility Evaluation.
724_H01_2015-2_FE FC_txt.docx 12-21-15
14
HARGIS + ASSOCIATES, INC.
Monitoring in Accordance with the Current Monitoring and Contingency Plan Ongoing groundwater and surface water monitoring is being conducted in accordance with the current MCP.
Surface water in Felicita Creek is currently monitored semi-annually at
11 locations for VOCs; annually at 2 additional locations for VOCs, and 3 locations for 1,4-dioxane annually. In accordance with the MCP, any detection of VOCs in Felicita Creek exceeding SWRBTLs would trigger a contingency response. The MCP contingencies have been developed to ensure that human health and the environment remain protected at the Site. The MCP monitoring is currently being implemented at the Site, therefore this remedial alternative will be the baseline case for comparison of the remaining remedial alternatives instead of the no-action alternative.
Artesian Treatment Vessels This treatment technology relies on using differential head between the groundwater (subject to natural artesian conditions) and the creek to convey the groundwater through treatment vessels installed below ground level.
No energy inputs or mechanical moving parts are required.
Groundwater flows upward through the treatment vessels which contain LGAC.
Treated
groundwater flows through a gravel diffusion bed near the creek.
In Situ Groundwater Treatment This category of treatment technology consists of treatment of VOCs in groundwater prior to flow into Felicita Creek. Treatments considered include: 1) bubbling air through the saturated zone to enhance volatilization of VOCs to the unsaturated zone and potentially enhance aerobic degradation of VOCs; 2) injection of chemical reagents and/or amendments to promote VOC degradation reactions; 3) installation of targeted plant species adjacent to the creek to promote phytoremediation of VOCs in groundwater; or 4) installation of a permeable reactive barrier to chemically degrade VOCs as groundwater flows through the barrier before entering the creek.
Ex Situ Surface Water Treatment This category of treatment technologies consists of treatment of creek water within the Felicita Creek channel.
Treatment may be accomplished through:
1) installation of bubbler
mechanisms to volatize VOCs in surface water; or 2) installation of structures that intercept the
724_H01_2015-2_FE FC_txt.docx 12-21-15
15
HARGIS + ASSOCIATES, INC.
surface water flow in the creek such as weirs, cascades, boulder clusters, or rip rap to enhance volatilization of VOCs by increasing the air/water contact.
Hydraulic Containment – Pump and Treat Pump and treat refers to one of the most well established and widely used remediation technologies. Implementation would involve installing vertical groundwater extraction wells in the shallow and/or deep zones with submersible pumps to intercept groundwater flows into Felicita Creek. Groundwater would be pumped and conveyed in above- and/or below-grade pipelines to a LGAC adsorption treatment system. Following treatment, treated groundwater would be conveyed to one of four disposal options: directly to Felicita Creek, through infiltration trenches/galleries to recharge groundwater, to irrigation reuse, or to the sanitary sewer.
2.3 SCREENING CRITERIA
Each potential remedial technology identified in Section 2.2 was screened based on Site-specific effectiveness and implementability.
The effectiveness of each remedial technology was addressed based on the ability to reliably reduce the flow of VOCs into Felicita Creek while minimizing changes to surface water flow in Felicita Creek.
The implementability evaluation addressed the technical and administrative feasibility of implementing each remedial technology at the Site considering Site conditions and administrative requirements.
A summary of the effectiveness and implementability screening of potential remedial technologies is presented in Table 5. Certain technologies were screened out at this level, and the rational is presented in Table 5. Retained technologies are discussed further below.

3.0 FELICITA CREEK REMEDIAL ALTERNATIVES ANALYSIS
The analysis of assembled remedial alternatives for Felicita Creek is presented in this section which includes the criteria used to evaluate the respective alternatives.
3.1 EVALUATION CRITERIA
Remedial alternatives were developed for Felicita Creek based on the remedial technologies retained from the previous section. Each remedial alternative was evaluated based on the following evaluation criteria:
Protection of Human Health and Environment,
Effectiveness,
Implementability,
Cost, and
Preservation of Water Resource.
A description of each evaluation criterion is provided in the following sections.
3.1.1 Protection of Human Health and the Environment Each remedial alternative was evaluated as to its overall protection of human health and the environment.
The remedial alternatives were assessed to determine the degree to which
potential human exposure is minimized or eliminated and the degree to which the Felicita Creek resource and surrounding area is protected.
724_H01_2015-2_FE FC_txt.docx 12-21-15
18
HARGIS + ASSOCIATES, INC.
3.1.2 Effectiveness Short-term effectiveness considers the effect of each remedial alternative on the protection of human health and the environment during the construction and implementation phase. Long-term effectiveness considers the likelihood that each remedial alternative will reduce VOC mass flux to Felicita Creek or the VOC concentrations in Felicita Creek.
3.1.3 Implementability The implementability evaluation addressed the technical and administrative feasibility of each remedial alternative. Technical feasibility was evaluated based on the ability to implement the remedial alternative given the existing Site-specific conditions. Administrative feasibility was evaluated based on the ability to obtain permits, gain State and community acceptance, and receive any off-property access required for the remedial alternative.
3.1.4 Cost Each remedial alternative was evaluated as to its relative expected cost (high, medium or low) compared to the other remedial alternatives.
Both capital and operation and maintenance
(O&M) costs were considered.
3.1.5 Water Resource Preservation Each remedial alternative was assessed to determine the degree to which the Felicita Creek water resource is preserved and changes in surface water flow caused by the respective remedial alternative is minimized.

HARGIS + ASSOCIATES, INC.
3.2 FELICITA CREEK REMEDIAL ALTERNATIVES
Each of the retained remedial alternatives for Felicita Creek are described below and evaluated based on the five evaluation criteria.
A summary of the pros and cons of each remedial
alternative is provided in Tables 6 and 7.
3.2.1 Alternative FC1: Current Monitoring and Contingency Plan (Baseline) The current MCP Alternative FC1 relies on the continued implementation of the provisions of the MCP (H+A, 2014b) to monitor the progress of cleanup in the creek. Current conditions indicate that reduction of VOCs will occur over time due to implementation of the GRS at the Site and natural attenuation processes in shallow groundwater.
The MCP outlines the groundwater and surface water monitoring that is conducted at the Site. Monitoring of shallow and deep groundwater in FCP and surface water in Felicita Creek is conducted on a semi-annual and annual basis. Surface water in Felicita Creek is monitored at 13 locations (Figure 5); shallow groundwater in FCP is monitored at 3 shallow monitor wells and 2 shallow regional wells (Figure 3); and deep groundwater in FCP is monitored at 3 deep monitor wells (Figure 4).
Triggers and contingencies have been identified in the MCP for potential receptors and hypothetical exposures to VOC-impacted groundwater and surface water. These contingencies have been developed to ensure that human health and the environment remain protected at the Site. The MCP also describes actions to be taken in the event that data collected or information developed during monitoring indicates the existence of a potential threat to human health or the environment. This MCP may also be updated in the event that data collected or information developed during monitoring indicates a potential threat to human health or the environment that may exist at the Site. Any detection of VOCs in surface water exceeding SWRBTLs will trigger a contingency response.
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
3.2.1.1 Protection of Human Health and the Environment Alternative FC1 is protective of human health and the environment by maintaining regular monitoring of groundwater and surface water concentrations within FCP. The results of this monitoring are compared to SWRBTLs and, currently, all VOCs are significantly below relevant SWRBTLs.
SWRBTLs have been derived and updated (Section 1.3) to ensure ongoing
protection of human health during water-contact activities at the creek. The current MCP would protect human health and the environment in the event of an exceedance, since an exceedance will trigger a contingency response. Given the highly conservative assumptions used to derive the SWRBTLs, the detection of a Site-related chemical in creek water at a concentration above its SWRBTL does not indicate that risks to recreational users at the creek exceed risk levels established by regulatory agencies.
There are no visual, construction, and/or operating impacts to Felicita Creek or FCP as a result of implementation of Alternative FC1.
3.2.1.2 Effectiveness Alternative FC1 is effective for monitoring the progress of VOC concentration reduction by natural attenuation processes in Felicita Creek. Surface water analytical results are compared to SWRBTLs and, in the event that SWRBTLs are exceeded, contingency responses are triggered.
Alternative FC1 does not actively accelerate the reduction of VOC mass flux or VOC concentrations in Felicita Creek, but future decreases of both VOC mass flux and VOC concentrations are anticipated in Felicita Creek as a result of natural attenuation of VOCs in shallow groundwater. Also, although concentrations of VOCs exceeding MCLs are observed in Felicita Creek in the northern portion of FCP (between surface water sampling locations FC-11 and FC-10), volatilization of VOCs is likely occurring downstream of surface water sampling location FC-10, as evidenced by the low detections or no detection of VOCs at surface water sampling location FC-7. VOC volatilization in shallow surface streams is commonly observed due to the high Henry’s Law constants and the exposure of the surface to ambient air conditions (Chapman et al., 2007).
724_H01_2015-2_FE FC_txt.docx 12-21-15
21
HARGIS + ASSOCIATES, INC.
There are no adverse long-term environmental impacts related to implementation of Alternative FC1.
3.2.1.3 Implementability Alternative FC1 is an established, successful procedure for monitoring VOCs in Felicita Creek and is highly implementable based on the ease of installation, availability of experienced contractors, reliability of technology, and simplicity of performance monitoring. Groundwater monitoring has been conducted in existing FCP monitor wells and regional wells for 9 to 20 years, and surface water monitoring has been conducted in Felicita Creek for approximately 20 years.
Groundwater and surface water sampling methods are based on conventional,
proven techniques. In addition, there would be no disruption to patrons other than semiannual collection of groundwater and surface water samples by a two person field crew.
Sample
collection at all groundwater wells and surface water locations would be completed in no more than 2 days per sampling event.
Administratively, Alternative FC1 has proven implementability with respect to agency coordination and access to monitoring locations within FCP.
3.2.1.4 Cost Alternative FC1 represents the baseline for remedial alternatives in Felicity Creek since these MCP activities are ongoing and required by DTSC. Therefore, there is no additional cost to implement this alternative because no activities are proposed beyond those currently conducted.
724_H01_2015-2_FE FC_txt.docx 12-21-15
22
HARGIS + ASSOCIATES, INC.
3.2.1.5 Water Resource Preservation Alternative FC1 preserves the water resource.
3.2.2 Alternative FC2: Ex Situ Treatment – Enhanced Volatilization Ex situ surface water treatment would consist of treatment of creek water within Felicita Creek, between sampling locations FC-11 and FC-10. Treatment would potentially be accomplished through installation of structures along approximately 1,400 lineal feet of Felicita Creek that would intercept the surface water flow and would enhance the natural volatilization of VOCs that is already occurring throughout the length of the creek. The structures, such as aeration weirs or boulders and rip rap may induce turbulent flow to increase gas transfer by air/water contact, thereby increasing the dissolved oxygen in the water and removing dissolved VOCs.
Studies have shown that the ratio between the aeration coefficient for oxygen and the volatilization coefficient for VOCs is constant for a given environmental condition (Pant et al., 2007), indicating that aeration processes may be potentially effective VOC stripping processes. The effectiveness of VOC removal would depend upon factors including the efficiency of the physical design of the structures to achieve air to water contact as well as environmental conditions such as water velocity, water depth, water and air temperatures, wind speed, and water quality.
In accordance with Section 404 of the Clean Water Act, installation of any
structure within the Felicita Creek channel will require authorization from the USACE.
Aeration Weirs/Cascades:
Aeration (oxygen addition) is routinely the first step during the
production of drinking water from groundwater or riverbank water, and one of the oldest hydraulic structures employed is the aeration weir or series of weirs, known as cascades (Toombes, L. and H. Chanson, 2000) (Figure 10A). Weir structures accomplish aeration and gas stripping (VOC removal) through a stepped drop in elevation, where the water falls over a weir into the water body at a lower elevation. When the falling water stream submerges in the receiving water body, air is entrained and dispersed in the form of bubbles, providing an improved interface between air and water. Gas transfer occurs at the interface between the water and the air bubbles and the residence time of entrained bubbles in the water body correlates with the stripping efficiency. Because the amount of air that is entrained is limited,
724_H01_2015-2_FE FC_txt.docx 12-21-15
23
HARGIS + ASSOCIATES, INC.
the capacity for gas transfer of VOCs through weirs and cascades is limited.
Weirs or
cascades, therefore, are commonly used in water treatment for the removal of methane and the addition of oxygen, and not typically used for the removal of VOCs when high removal efficiencies are required (Van Dijk, J.C., 2007). The expected TCE removal efficiency in a cascade system is less than 50 percent. The air water interface ratio may possibly be improved by adding baffles to produce additional turbulence.
Installation of weirs would involve construction of multiple barriers across the creek, designed to accumulate (pool) water behind the weir until the water level rises to the height of the weir and flows steadily over the top (Figure 10B). Key components to the aeration and VOC stripping efficiency of the weir is the drop (fall) height of each weir, receiving water depth, weir discharge rate, and the number of weir steps forming the cascade system, although the efficiency of the system is limited, as described previously. An efficient VOC-removal weir drop height in the northern 1,400 feet of the east fork of Felicita Creek between FC-11 and FC-10 would be difficult to achieve due to the minimal elevation relief. The northern-most 400-foot section of the east fork between FC-11 and FC-12 has an approximately 5-foot elevation decline, the next 500-foot section between FC-12 and south of FC-15 has an approximately 15-foot elevation decline, and the next 500-foot section between FC-15 and Clarence Lane has an approximately 5-foot elevation decline.
Detailed engineering evaluation and field testing in the creek would be required to design each weir structure, but given the minimal elevation relief over long distances, it can be assumed that many
short-drop
weir

distances
of
pooled/accumulated water behind (upgradient) of each structure. A series of cascade-type check dams, installed during the Work Projects Administration in the 1930’s, are currently located in Felicita Creek in the vicinity of surface water sampling location FC-7, where the creek gradient is much steeper.
Boulders and/or Rip Rap: In-stream structures such as rip/rap, boulder clusters, and riffles have typically been used to enhance stream habitat for the benefit of fish and other aquatic organisms (Fischenich, C. and R. Seal, 2000; Washington Department of Forestry, 2004). In order to be effective, water velocities must be sufficient so that these structures create flow separation and lead to the formation of eddies or vortices in their wake.

In addition to

enhancing stream habitat, these flow characteristics may be also useful to enhance volatilization of VOCs. Aeration may be increased by strategic placement of rip rap and/or large (greater than 1 cubic yard) immobile boulders within the creek bed to create velocity gradients and turbulence as the water travels along a more tortuous path around and over these features (Figure 10A). Boulder placement creates a diversity of water depths and velocities which would provide air bubbles and turbulence as the boulders induce water velocity gradients, where slow water velocities occur in close proximity to faster velocities.
This induced turbulence may
increase the air water contact to enhance volatilization.
Installation of boulder clusters or rip-rap in the northern-most portion of the east fork of Felicita Creek between FC-11 and FC-12 is unlikely to induce the flow characteristics necessary to enhance volatilization. This portion of the creek has minimal elevation relief and water velocity is slow and visually imperceptible. Boulder installation would be focused on the 1,100-foot portion of Felicita Creek between FC-12 and FC-10.
There are currently large boulders located in Felicita Creek between surface water sampling locations FC-14 and FC-5, which create turbulent flow.
3.2.2.1 Protection of Human Health and the Environment Although implementation of the current MCP is protective of human health and the environment, Alternative FC2 is marginally more protective. Enhanced volatilization would protect human health and the environment by accelerating the rate of volatilization to reduce VOC concentrations in a shorter distance than is currently occurring.
The potential for human
exposure may be marginally reduced and the VOC concentrations within Felicita Creek may be reduced. Alternative FC2 provides protection of the environment by preserving the flow of water in Felicita Creek.

3.2.2.2 Effectiveness Installation of enhanced volatilization structures (aeration weirs/cascades or rip rap) in Felicita Creek is anticipated to be marginally effective at accelerating the rate of volatilization to reduce VOC concentrations in Felicita Creek more rapidly and within a shorter distance than is currently occurring due to natural attenuation. The effectiveness will be variable, depending on creek flowrate. The total mass of VOCs transferred to the air due to the enhanced volatilization would dissipate immediately and not pose a risk to human health.
The enhanced volatilization
structures may require periodic maintenance to remove accumulated natural debris that would reduce their effectiveness.
3.2.2.3 Implementability Construction of the enhanced volatilization structures throughout a 1,100- to 1,400-foot section of the northern portion of Felicita Creek would result in a short-term significant disruption to Felicita Creek and FCP. These impacts would include temporary restriction of access to the northern portion of Felicita Creek and FCP and noise associated with construction.
Construction of weirs would require diversion of the creek or the use of temporary cofferdams to allow the enclosed creek area to be pumped out and create a dry work environment. Sheet piles associated with the cofferdams may be left in place to avoid damage to the newly constructed weir.
The weir structures would be installed across the creek channel and
embedded in the creek banks in multiple locations with footings for the weirs extending below the creek bed at sufficient depth to stabilize the structures.
Installation of boulder clusters would require careful placement of rock. Typically, a hydraulic excavator with a bucket and thumb attachment that can easily move the boulders is used.
For both weir installation and boulder cluster placement, the number and location of access points should be carefully selected to minimize trampling and damage to bank slopes and riparian vegetation as the heavy equipment moves up and down the creek channel. At project completion, disturbed areas will need to be graded smooth, seeded, and planted to repair damage and restore the riparian zone.

Technical implementability of Alternative FC2 is moderately difficult, requiring an iterative approach. Performance testing and possible modification would be required for each structure installed throughout the 1,100- to 1,400-foot length of Felicita Creek between surface water sampling locations FC-11 and FC-10 due to the unique creek conditions at each location.
Long-term impacts associated with Alternative FC2 include altering the existing nature of flow within Felicita Creek and disturbance of the stream bed, although similar structures are currently present in Felicita Creek. Construction of cascades or boulders and rip rap can be designed to use materials that visually blend with the natural environment of Felicita Creek and have the appearance of natural features. At project completion, all structures could be removed.
Alternative FC2 would be difficult to implement, based on permitting requirements.
As
discussed with RWQCB and USACE during technical meetings on August 16, 2015, this project would require extensive permits. FCP is a California State Historic Site, and both access and approval to implement Alternative FC2 would require negotiation with the County of San Diego Parks Department. There are multi-jurisdictional permitting requirements including:
Obtain USACE approval for installation of any structure within Felicita Creek, in accordance with Section 404 of the Clean Water Act;
Obtain determination from RWQCB in accordance with Section 403 of the Clean Water Act;
Consult with California Department of Fish and Wildlife regarding design of VOC mitigation for necessary permits;
Perform Biological Surveys to support environmental permits;
California Environmental Quality Act (CEQA) evaluation and determination by DTSC; and
Conduct public notification and community relations.

3.2.2.4 Cost The Alternative FC2 costs would be high. Costs would include a complex approval process to negotiate access in FCP, multi-jurisdictional permitting, CEQA review, and biological surveys; capital costs for the significant construction effort; and O&M costs for periodic inspection and debris removal.
3.2.2.5 Water Resource Preservation Alternative FC2 does not alter the volume of flow in Felicita Creek, but does promote turbulent flow characteristics. Therefore, Alternative FC2 preserves the water resource.
3.2.3 Alternative FC3A: Hydraulic Containment with Treated Water to Surface Water Hydraulic containment of groundwater that flows to Felicita Creek would be accomplished using pump and treat technology. A conceptual design for evaluation purposes was developed and has been evaluated. Any design would need to be reviewed and approved by the San Diego County Parks Department. Implementation may include installation of three to five or more groundwater extraction wells located along the axis of the northern portion of Felicita Creek between sampling locations FC-11/11A and FC-10, to intercept shallow groundwater flow to Felicita Creek. Groundwater would be pumped by submersible pumps installed in each extraction well and conveyed through approximately 1,400 feet of above- and/or below-grade, double-contained pipelines to a LGAC adsorption treatment system. Conveyance piping will be installed adjacent to Felicita Creek. Based on professional judgment, simple capture analysis, and hydraulic information from groundwater monitoring, it is assumed that the total flowrate to the LGAC adsorption treatment system would be approximately 20 to 40 gallons per minute. The LGAC adsorption treatment system would consist of two 2,000-pound carbon adsorbers, a 2,000-gallon utility tank, a transfer pump, and a control system and would be located on a 20-foot by 20-foot concrete pad with spill containment dike, surrounded by fencing. If access approval can be obtained from FCP, the treatment system could be installed adjacent to the old county firehouse building at FCP (Figures 11A and 11B).
724_H01_2015-2_FE FC_txt.docx 12-21-15
28
HARGIS + ASSOCIATES, INC.
Conveying treated water to Felicita Creek would require construction of a structure in the northern portion of FCP and approximately 300 feet of above- and/or below-grade treated water pipeline from the effluent of the LGAC adsorption treatment system at the old county firehouse to Felicita Creek.
Felicita Creek is located within the Felicita HSA, which is designated for beneficial use as municipal and domestic supply. Returning treated groundwater to Felicita Creek would require obtaining a NPDES permit under the General Waste Discharge Requirements for Groundwater Extraction Discharges to Surface Waters within the San Diego Region, San Diego RWQCB Order No. R9-2015-0013/NPDES No. CAG919003. Consultation with the RWQCB indicates treatment of TDS, chloride, nitrate, total nitrogen, sulfate, manganese, and iron which occur in regional groundwater would be required. Treatment for these constituents is not feasible due to the generation of a brine stream that must be disposed of via sanitary sewer. Sanitary sewer capacity is not currently available in the vicinity of FCP. Surface monitoring and reporting would be required as stipulated by the NPDES permit.
3.2.3.1 Protection of Human Health and the Environment Although implementation of the current MCP is protective of human health and the environment, Alternative FC3A is marginally more protective by reducing the mass flux of VOCs into Felicita Creek. The potential for human exposure would be reduced and the VOC concentrations within Felicita Creek would be reduced.
Alternative FC3A provides protection of the environment by preserving the flow of water in Felicita Creek by conveying treated water to the creek, but installation and construction activities will cause significant disruption to the northern portion of FCP adjacent to a sensitive creek.
3.2.3.2 Effectiveness Hydraulic containment is potentially effective for capturing shallow and deep groundwater in the targeted area and LGAC is a proven effective technology for reducing VOC concentrations in extracted water. LGAC would not reduce other constituents in groundwater including TDS,
724_H01_2015-2_FE FC_txt.docx 12-21-15
29
HARGIS + ASSOCIATES, INC.
chloride, sulfate and other non-VOCs that may require treatment to comply with discharge requirements for the NPDES permit. The extraction system can be designed and implemented to minimize mass flux of VOCs into Felicita Creek between surface water sampling locations FC-11 and FC-10. Treated water returned to the creek would mix with VOCs flowing into the creek outside of the extraction capture zone, but may not achieve MCLs throughout the creek in the short-term.
3.2.3.3 Implementability During the construction of Alternative FC3A, there would be a short-term significant disruption to Felicita Creek and FCP.
These impacts would include noise and traffic associated with
construction and temporary restriction of access to the northern portion of FCP from Felicita Creek to the old county firehouse. Construction activities would include drilling and installation of the shallow and deep extraction wells and associated wellhead equipment; installation of the treatment system; trenching for installation of electrical conduit, conveyance pipelines, and treated water pipelines; and construction of a water return structure. Construction equipment and activities would potentially impact the sensitive creek and park environment and restoration activities may be required. During the operational phase, there will be a loss of use of the treatment system area to FCP and park patrons, although there is minimal potential human exposure to VOCs from operation of the treatment system. Construction in and below the ordinary high water mark in the vicinity of Felicita Creek will trigger the need for Section 404 and 403 permits issued by USACE and RWQCB, respectively. O&M of the treatment system and disposal structure will necessitate regular visits by the treatment system operator and/or other contractors.
Technical implementability of Alternative FC3A is moderate.
Design and installation of
groundwater extraction wells for hydraulic containment and LGAC treatment systems are standard practice. Extraction well locations could be sited to minimize impacts to existing FCP features.
Experienced drillers and contractors are available.
O&M of the treatment and
disposal systems are standard practice and experienced operators are available.
Alternative FC3A would be difficult to implement, based on administrative challenges. FCP is a California State Historic Site, and both access and approval to implement Alternative FC3A
724_H01_2015-2_FE FC_txt.docx 12-21-15

HARGIS + ASSOCIATES, INC.
would require negotiation with the County of San Diego Parks Department. There are multi-jurisdictional permitting requirements including:
Obtain USACE approval for installation of any structure within the Felicita Creek or below the ordinary high water mark, in accordance with Section 404 of the Clean Water Act;
Obtain determination from RWQCB in accordance with Section 403 of the Clean Water Act;
Consult with California Department of Fish and Wildlife regarding design of VOC mitigation for necessary permits;
Perform Biological Surveys to support environmental permits;
CEQA evaluation and determination by DTSC;
Obtain NPDES permit; and
Conduct public notification and community relations.
Returning treated water to Felicita Creek would not be feasible due to treatment requirements for inorganic constituents including TDS, chloride, nitrate, and sulfate.
Treatment of these
constituents generates a brine stream that must be disposed of via sanitary sewer. Sanitary sewer capacity is not currently available in the vicinity of FCP.
3.2.3.4 Cost Alternative FC3A costs would be high. Costs would include a complex approval process to negotiate access, multi-jurisdictional permitting, CEQA review, and biological surveys; capital costs for the significant construction effort; O&M costs including monitoring in accordance with the NPDES permit.

3.2.3.5 Water Resource Preservation Alternative FC3A returns the treated water to the creek and preserves the water resource.
3.2.4 Alternative FC3B: Hydraulic Containment with Treated Water to Subsurface Hydraulic containment of groundwater that flows to Felicita Creek would be accomplished using pump and treat technology, as described in Alternative FC3A (Section 3.2.3). The remedial alternative would be designed to be outside the delineated area of Felicita Creek to eliminate the need for Section 404 and 403 permits issued by USACE and RWQCB, respectively.
Returning treated groundwater to the subsurface would require construction of one or more infiltration trenches to recharge groundwater. The infiltration trench(es) could be located near surface water sampling location FC-11. Typical infiltration trenches consist of a 3-foot to 6-foot deep trench, lined with filter fabric and backfilled with aggregate (EPA, 1999). Generally, a sand layer is provided at the base of the trench, aggregate is used to fill the trench to approximately 2 inches below grade and a 2-inch thick pea gravel layer overlies the top.
Treated water
conveyed to the infiltration trench passes downward through the void space between the stones and infiltrates through the trench bottom and into the soil matrix, and recharges groundwater.
Infiltration trenches must have routine inspection and maintenance. The principal maintenance objective is to prevent clogging, which may lead to reduced infiltration capacity. An observation well is recommended to monitor water levels in the trench, generally a 4- to 6-inch diameter pipe which is anchored vertically to a foot plate at the bottom of the trench. Inadequate drainage may indicate the need for maintenance.
Felicita Creek is located within the Felicita HSA, which is designated for beneficial use as municipal and domestic supply. Infiltration of treated groundwater would require obtaining a permit under the General Waste Discharge Requirements for Discharges of Treated Groundwater from Volatile Organic Compound Cleanup Sites to Land in the San Diego Region (WDR), San Diego RWQCB Order No. R9-2008-0138. Infiltration groundwater would require RWQCB to adopt permit limits for TDS, chloride, nitrate, total nitrogen, and sulfate consistent

32
HARGIS + ASSOCIATES, INC.
with regional groundwater quality. Monitoring and reporting would be required as stipulated by the WDR permit.
3.2.4.1 Protection of Human Health and the Environment Although implementation of the current MCP is protective of human health and the environment, Alternative FC3B is marginally more protective by reducing the mass flux of VOCs into Felicita Creek. The potential for human exposure would be reduced and the VOC concentrations within Felicita Creek would be reduced.
Alternative FC3B may result in the loss of flow to the creek if the infiltrated water promotes growth of plants that increase evapotranspiration and installation and construction activities will cause significant disruption to the northern portion of FCP adjacent to a sensitive creek.
3.2.4.2 Effectiveness Hydraulic containment is potentially effective for capturing shallow and deep groundwater in the targeted area and LGAC is a proven effective technology for reducing VOC concentrations in extracted water. The extraction system can be designed and implemented to minimize mass flux of VOCs into Felicita Creek between surface water sampling locations FC-11 and FC-10. There is the potential for loss of flow in the creek if infiltrated water does not flow into the creek. A portion of the infiltrated groundwater may also be recaptured by the extraction wells reducing the overall effectiveness of this alternative. Alternative FC3B may not achieve MCLs throughout the creek in the short-term.
3.2.4.3 Implementability During the construction of Alternative FC3B, there would be a short-term significant disruption to Felicita Creek and FCP.
These impacts would include noise and traffic associated with
construction and temporary restriction of access to the northern portion of FCP from Felicita Creek to the old county firehouse. Construction activities would include drilling and installation of the shallow and deep extraction wells and associated wellhead equipment; installation of the

treatment system; trenching for installation of electrical conduit, conveyance pipelines, and treated water pipelines; and construction of the infiltration trench(es). During the operational phase, there will be a loss of use of the treatment system area and infiltration trench area to FCP and park patrons, although there is minimal potential human exposure to VOCs from operation of the treatment system. O&M of the treatment system and infiltration trench(es) will necessitate regular visits by the treatment system operator and/or other contractors. Periodically, the infiltration trenches will require rehabilitation and or replacement to restore loss of capacity due to fouling.
Technical implementability of Alternative FC3B is moderate.
Design and installation of
groundwater extraction wells for hydraulic containment and LGAC treatment systems are standard practice. Experienced drillers and contractors are available. O&M of the treatment and disposal systems are standard practice and experienced operators are available.
Alternative FC3B would be difficult to implement, based on administrative challenges. FCP is a California State Historic Site, and both access and approval to implement Alternative FC3B would require negotiation with the County of San Diego Parks Department. The San Diego County Parks Department in the August 25, 2015 technical meeting indicated a strong preference for alternatives that do not have extensive underground infrastructure and require new facilities. There are multi-jurisdictional permitting requirements including:
Consult with California Department of Fish and Wildlife regarding design of VOC mitigation for necessary permits;
Perform Biological Surveys to support environmental permits;
Determine CEQA requirements for CEQA evaluation, if required; and
Conduct public notification and community relations.

HARGIS + ASSOCIATES, INC.
3.2.4.4 Cost Alternative FC3B costs would be high. Costs would include a complex approval process to negotiate access, multi-jurisdictional permitting, CEQA review, and biological surveys; capital costs for the significant construction effort; O&M costs including monitoring in accordance with the WDR permit. Maintenance of the infiltration trench(es) would be costly due to fouling.
3.2.4.5 Water Resource Preservation Alternative FC3B would be designed for maximum return of the treated water to the creek, but there is potential loss of flow in the creek if a portion of infiltrated water is lost to increase plant growth in the vicinity of the infiltration trench(es).
3.2.5 Alternative FC3C: Hydraulic Containment with Non-Potable Reuse Hydraulic containment of groundwater that flows to Felicita Creek would be accomplished using pump and treat technology, as described in Section 3.2.3.
Irrigation reuse at FCP would require installation of a water storage tank and associated pumps, pipelines, and controls to connect the effluent of the treatment system to the FCP irrigation distribution system.
3.2.5.1 Protection of Human Health and the Environment Although implementation of the current MCP is protective of human health and the environment, Alternative FC3C is marginally more protective of human health by reducing of the mass flux of VOCs- into Felicita Creek, but would not protect the environment due to the loss of water flow in the creek due to losses associated with evapotranspiration in the irrigated area. Given the seasonally variable demand for irrigation water, there would likely be periods of time when the system could not be operated, allowing for continued flow into the creek.

3.2.5.2 Effectiveness Hydraulic containment is potentially effective for capturing shallow and deep groundwater in the targeted area and LGAC is a proven effective technology for reducing VOC concentrations in extracted water. The extraction system can be designed and implemented to minimize mass flux of VOCs into Felicita Creek between surface water sampling locations FC-11 and FC-10. Treated water would not be returned to the creek system, but would be used for irrigation within FCP. Alternative FC3C may not achieve MCLs throughout the creek in the short-term.
During the operational phase, there will be a loss of use of the treatment system area to FCP and park patrons, although there is minimal potential human exposure to VOCs from operation of the treatment system. O&M of the treatment system will necessitate regular visits by the treatment system operator and/or other contractors.

need for additional irrigation water at FCP. It is unlikely that another irrigation water user could be identified in the vicinity of FCP.
There are multi-jurisdictional permitting requirements
including:
Obtain WDR permit with waiver of permit limits for TDS, chloride, sulfate, nitrate, total nitrogen;
Consult with California Department of Fish and Wildlife regarding design of VOC mitigation for necessary permits;
Perform Biological Surveys to support environmental permits;

4.0 COMPARISON OF ALTERNATIVES
The Felicita Creek alternatives include passive and active remedial mechanisms to reduce VOCs:
monitoring and natural attenuation (Alternative FC1); construction of structures in
Felicita Creek to enhance volatilization (Alternative FC2); and hydraulic containment and treatment of extracted groundwater (Alternatives FC3A, FC3B, and FC3C). Three treated water options were considered for the hydraulic containment option: Felicita Creek (FC3A), infiltration trench (FC3B), and irrigation reuse (FC3C).
Protection of Human Health and Environment
Current concentrations detected in Felicita Creek have not exceeded any of the SWRBTLs and risk analyses for Felicita Creek concluded that Site-related contaminants within Felicita Creek are protective of human health and the environment (H+A, 2012; DTSC, 2014a and 2014c). Alternatives FC1, FC2, and FC3 (A to C) provide protection of human health through continued surface water monitoring in Felicita Creek and comparison of analytical results to SWRBTLs. Current conditions indicate that VOC reductions will occur over time through natural attenuation processes. Alternatives FC2 and FC3 (A to C) are marginally more protective of human health than FC1 by marginally reducing the potential for human exposure to VOCs: FC2 is anticipated to limit VOC exposure to a shorter distance within Felicita Creek and FC3 (A to C) is expected to reduce the mass flux of VOCs into Felicita Creek. Alternatives FC1, FC2, and FC3A provide protection of the environment by preserving the flow of water in Felicita Creek, with Alternative FC3B performing similarly and Alternative FC3C performing less favorably due to water losses due evapotranspiration in the irrigated area(s).
Effectiveness
Alternative FC1, FC2, and FC3 are expected to reduce VOCs in Felicita Creek.
The
mechanism for VOC reduction in Alternative FC1 is natural attenuation, for Alternative FC2 is enhanced volatilization of creek water, and for Alternative FC3 is hydraulic containment and treatment of extracted groundwater with LGAC. Alternative FC2 is anticipated to provide VOC reduction in Felicita Creek more quickly and within a shorter distance than Alternative FC1.
724_H01_2015-2_FE FC_txt.docx 12-21-15
38
HARGIS + ASSOCIATES, INC.
Alternatives FC3A, FC3B, and FC3C are expected to intercept groundwater containing VOCs prior to flow into Felicita Creek, and reduce the mass flux of VOCs to Felicita Creek. Alternative FC3A will return the treated water directly to the creek and mix with VOC-impacted water flowing in the creek.
Alternative FC3B will recharge groundwater and mix with
VOC-impacted water flowing in the creek, although the mixing effect will be lower than Alternative FC3A. Alternative FC3C will reduce the mass flux of VOCs to Felicita Creek, but would be subject to seasonal water demand and result in reduced operation of the system during the wet season.
Implementability
Alternative FC1 is the most implementable alternative. Alternatives FC2 and FC3B are difficult to
implement
due
to
the
approval/permits
and
access
requirements,
respectively.
Alternatives FC3A and FC3C cannot be practically implemented due to the natural inorganic water quality/permit requirements and lack of need for irrigation water by FCP, respectively.
Cost
Alternative FC1 has a low associated cost. Alternatives FC2, FC3A, FC3B, and FC3C have high costs.
Water Resource Preservation
Alternative FC1 preserves the flow in Felicita Creek with no adverse impacts to the creek. Alternative FC2 preserves flow in the creek with limited adverse impact due to installation of structures in the creek. Alternative FC3A preserves the flow in Felicita Creek, Alternative FC3B may reduce the flow in Felicita Creek if a portion of infiltrated water does is lost before flowing into the creek, and Alternative FC3C has the greatest potential to decrease the flow in Felicita Creek between surface sampling locations FC-11 and FC-10.

HARGIS + ASSOCIATES, INC.
Preferred Alternative
FC-1 is the preferred alternative. It is protective of human health and the environment, it is implementable while the other alternatives may not be due to permitting limitation. FC-1 is least disruptive and preserves the water resource.

Alternative Description
Pros
FC1: Monitor in accordance with MCP
Effective for monitoring the progress of cleanup in the creek Allows evaluation of surface water quality to SWRBTLs Maintains the resource with no visual, construction and/or operating impacts to Felicita Creek or the Park Clean up will rely on natural attenuation Protection of Human Health and Environment Easily implementable No additional cost
VOC reduction rate in creek limited by natural processes, VOC reduction not achieved until southern portion of park
FC2: In–Situ Treatment – Enhanced volatilization of VOCs through installation of structures in Felicita Creek (Weirs or Boulder Clusters)
Some methods (boulder clusters) do not require ongoing maintenance Preserves the flow in Felicita Creek
This naturally occurs, just intensifying rate of volatilization to reduce VOCs more rapidly and in shorter distance within the Park Significant engineering design and disturbance of stream bed Multi-jurisdiction approvals/permits required Visual, construction and/or operating impacts to the Felicita Creek or the Park High cost

TABLE 7 HYDRAULIC CONTAINMENT DISPOSAL OPTION ANALYSIS FOR ALTERNATIVE FC3 FELICITA CREEK, CHATHAM SITE, ESCONDIDO CALIFORNIA Potential Disposal Options for Alternative FC3
Alternative Description
Pros
Cons
A
Stream Disposal Return VOC-treated groundwater to Felicita Creek to maintain stream flow
Relatively simple and easy to maintain Maintains resource and flowing creek Potential mixing of VOCs flowing into creek to reduce concentrations from outside capture zone
Groundwater that currently flows to creek contains constituents that will not be treated using carbon, and either A) RWQCB waives discharge limits for NPDES permit (for example - TDS, chloride, sulfate and other non-VOCs) OR B) additional, much more costly treatment with larger footprint would be required If additional inorganic treatment is required, this disposal option not likely feasible. Inorganic treatment generates another waste stream that cannot be readily be disposed of If inorganic treatment not required, lower cost when compared to other disposal options
B
Subsurface Disposal Return VOC-treated groundwater to subsurface by construction of infiltration trench structure(s) to recharge treated water
Permitting may be less stringent for non-Site related compounds as compared to A Maintains water resource (potential small loss of flow in the creek if increased evapotranspiration in vicinity of trench(es) due to plant growth)
Maintenance of infiltration trench would be high due to potential biofouling or plugging (fouling) Greater surface disruption and long-term access to replace/rehabilitate infiltration system Moderate cost when compared to other disposal options
C
Irrigation Reuse
Potentially lower cost when compared to other disposal options
Not viable as a stand-alone disposal alternative due to variability of daily and seasonal demand Water resource is not maintained due to evaporation losses

GC/MS Semi VOA Method(s) 625: The continuing calibration verification (CCV) associated with batch 258691 recovered above the upper control limit for benzoic acid. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The following samples are impacted: MW-58-20150521 (440-110716-1), MW-66-20150521 (440-110716-2), MW-53-20150521 (440-110716-3), MW-54-20150521 (440-110716-4), MW-70-20150521 (440-110716-5) and (CCVIS 440-258691/2). Method(s) 625: The percent recoveries for the laboratory control sample (LCS) in batch 257104 failed below the lower acceptance limits for the following analytes: 3-nitroaniline; 4-chloroaniline and 3,3'-dichlorobenzidine. Low recoveries are possibly due to less than optimal extraction conditions such as fluctuations in heating mantle temp, condenser water temp, ambient light, angle of apparatus, spike solvent, final volume measurements, etc. The affected samples could not be reextracted within sample hold time. Method(s) 625: The %RPD of the laboratory control sample (LCS) and laboratory control standard duplicate (LCSD) for preparation batch 257104 recovered outside control limits for the following analytes: 3,3'-dichlorobenzidine; 3-nitroaniline; 4-chloroaniline; and 4-nitroaniline. Method(s) 625: The laboratory control sample duplicate (LCSD) for batch 257104 recovered outside control limits for 3-nitroaniline. This analyte was biased high in the LCSD and was not detected in the associated samples; therefore, the data have been reported. Method(s) 625: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with 257104. The laboratory control sample (LCS) was performed in duplicate to provide precision data for this batch. Method(s) 625: The laboratory control sample (LCS) for batch 257104 recovered outside control limits for benzidine.
