The South Norwalk Electric and Water (SNEW) is proud to report that the quality of drinking water it supplies to you, our customer, meets or surpasses all federal and state drinking water standards. SNEW tests its water using sophisticated equipment and advanced procedures. We perform over 30,000 analyses annually on about 3,500 samples while looking for more than 90 possible contaminants. Nearly all analyses are conducted by the SNEW’s state certified public health laboratory, number PH-0461.

This "2003 Water Quality Report", or Consumer Confidence Report, states where your water comes from, how it is treated and monitored, what it contains and how it compares to standards set by regulatory agencies.

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.

Your drinking water is surface water that comes from four reservoirs located in the Towns of Wilton and New Canaan. They include City Lake, Rock Lake and Popes Pond Reservoirs in Wilton and the New Canaan Reservoir in New Canaan. The watershed area totals 6,300 acres in these towns, with SNEW owning about 19%. We have an excellent watershed protection program which includes property inspections and water quality sampling to safeguard our sources from pollution and to insure that we maintain the highest quality water in these reservoirs.

A source water assessment of our supply system was recently completed by the Department of Public Health Drinking Water Division. The updated assessment report can be found on the Department of Public Health website: http://www.dph.state.ct.us/BRS/Water/SWAP/swap.htm. The assessment found that our public drinking water source has a low susceptibility to potential sources of contamination.

Our customers can play an important role in helping to preserve this most important natural resource in two ways, source protection and conservation. Inspecting septic systems on a regular basis and promptly repairing any problems, using fertilizers sparingly and carefully following manufacturer’s directions, replacing leaky oil tanks, disposing of hazardous household materials properly and reporting any incidences of pollution are ways customers can help to protect the source. Practicing conservation will help to maintain an adequate supply of clean drinking water. Promptly fixing toilet leaks and leaking fixtures, turning off the faucet when shaving and brushing teeth and running dishwashers and washing machines with full loads are ways you can conserve water and save money on your water bill too.

Microbial contaminants, such as viruses and bacteria which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining and farming.

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm runoff, and septic systems.

Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, 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.

Water from the reservoirs undergoes rigorous treatment at our Filtration Plant in Wilton. We employ processes such as alum coagulation, sedimentation and filtration to remove impurities from the raw water. A disinfectant is added to protect against microbial contaminants. Fluoride is added to aid in dental health. We serve about 40,000 people and treat approximately 4.7 million gallons of water per day, which is distributed through a network of 135 miles of pipeline.

To insure the purity of the water supplied to you, we undertake an elaborate water sample collection and testing program. Our source water monitoring, performed on a weekly basis, serves as an early warning system for potential pollution of our reservoirs. The water then goes through our filtration facility and is tested continuously at various stages to monitor the performance of the treatment processes. Finally, we collect samples from the distribution system, as well as at taps of individual customers, to insure the quality of the water you drink.

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 contacting the EPA’s Safe Drinking Water Hotline at 1-800-426-4791 or hotline-sdwa@epa.gov.

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 infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791 or hotline-sdwa@epa.gov.

* Although there is no EPA MCL for Sodium, the State of CT requires that systems exceeding 28 ppm are required to notify their customers, so that individuals on a sodium restricted diet can inform their physician.

Lead: Infants and young children are typically more vulnerable to lead in drinking water than the general population.  It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing.  If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water.  Additional information is available from the Safe Drinking Water Hotline at 1-800-426-4791.

Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water.  MCLs are set as close to MCLGs as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health.  MCLGs allow for a margin of safety.

Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water.  There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health.  MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination.

Nephelometric Turbidity Unit (NTU): A measure of the cloudiness of water.  We monitor turbidity because it is a good indicator of the effectiveness of our filtration system.

Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.

ppm: Parts per million, or milligrams per liter (mg/l).

ppb: Parts per billion, or micrograms per liter (mg/l).

N/A: Not applicable
