ABOUT NITRATE - Nitrate in drinking water at levels of 10 ppm and above is a health hazard to infants less than six months old. This high level can cause “blue baby syndrome” and you should consult your doctor. The Tanglewood Water Division does NOT have a high nitrate level in our water and it is checked annually Some people who drink water containing trialomethanes in excess of the MCL over many years may experience problems with their liver, kidneys or central nervous systems and may have an increased risk of getting cancer.. ABOUT ATRAZINE VIOLATIONS: During the spring months, a big surge in the use of atrazine-based herbicides by farmers could enter the water system. The EPA has been working with state and local farmers to solve this problem. High atrizine levels can affect cardiovascular systems and cause reproductive difficulties. At Tanglewood we do not have this problem, but must continue to monitor the situation. Questions about atrizine can be discussed by calling the Geauga Health Department at 440-285-2222.

ABOUT LEAD - If present, elevated levels of lead can cause serious health problems for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The Tanglewood Water Division is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at “http//www.epa.gov/safewater/lead”.

TANGLEWOOD WATER DIVISION Water Quality Report for 2010

drinking water from their health care providers. EPA/Center for Dosage Control guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).

INTRODUCTION - The Tanglewood Water Division has prepared the following report to provide information to you, the consumer, on the quality of our drinking water. Included within this report is general health information, water quality test results, how to participate in decisions concerning your drinking water and water system contacts. No Federally Mandated Maximum Contaminant Levels or Action Levels were exceeded, nor were any Variances or Exemptions required. In calendar year 2010, we pumped a total of 42,633,000 gallons of water from our water wells.

ABOUT YOUR DRINKING WATER - The Tanglewood Water Division has a current, unconditioned license to operate our water system. The EPA requires regular sampling to ensure drinking water safety. The Tanglewood Water Division conducted sampling for bacteria throughout 2010. Nitrate was tested in 2010. Synthetic organic, lead and copper contaminant sampling was conducted in 2009. The Ohio EPA allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Therefore, some of our data, though accurate, are more than one year old. During 2010, the Tanglewood Water Division did not fail published limits for any contaminant. The Tanglewood Water Division is not in violation or failure to complete proper lead and copper corrosion control. Listed below is information on those contaminants that were found in the Tanglewood Water Division drinking water.

WATER SOURCE INFORMATION - The Tanglewood Water Division pumps its drinking water from ten (10) wells; seven (7) of which are located in the Berea Aquifer adjacent to the water pumping plant at 17400 Haskins Road; three (3) other wells in the Sharon Aquifer are located north of the plant adjacent to the ball field at the corner of East Washington Street and Haskins Road. All water from these wells is piped to the treatment plant on Haskins Road where it is treated to remove dissolved iron, add fluoride to control tooth decay and chlorine to disinfect the water. The treated water is piped to underground storage reservoirs from which our high pressure pumps draw to supply water to the water distribution system. A backup diesel generator allows water pressure to be maintained during periods of electrical power failure. The Tanglewood Water Division also has an emergency supply agreement with the Chagrin Water Company. During 2010, we did not use any water from this emergency source. This report does not contain information on the water quality of the Chagrin Water Company but a copy of their Consumer Confidence Report may be obtained from Chagrin. They can be contacted at (440) 247-5050. Both Tanglewood Water Division and the Chagrin Water Company must meet all EPA water quality tests and regulations. WHAT ARE SOURCES OF CONTAMINATION TO DRINKING WATER - The sources of drinking water, both tap water and bottled water, include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

In order to ensure that tap water is safe to drink, the EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Drinking water, including bottled water may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (1-800-426-4791).

WHO NEEDS TO TAKE SPECIAL PRECAUTIONS? - Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infection. These people should seek advice about
