Pesticides in CT Well Water: Health officials in Connecticut are telling residents who drink from private wells to test their water for the banned pesticides chlordane and dieldrin, after a study from the town of Stamford, CT found at least one of the toxic chemicals in 195 out of 628 wells tested. Over half of the wells that tested positive for one of the pesticides were found to contain concentrations at levels above what the EPA considers acceptable.
Both of these chemicals were widely used throughout the country before their ban in the late 1980s. In 2009, the U.S Housing and Urban Development (HUD) and EPA conducted a survey that found chlordane in 64% of U.S households sampled. The results from Stamford, CT are considered to be only the tip of the iceberg.
The Stamford Health Department began its study in 2009 after testing revealed pesticide contamination near a local town dump. Health officials expected the results to be localized, but were caught off guard as the chemicals were identified in areas away from the dump. Sharee Rusnak, epidemiologist for the Connecticut Department of Public Health said, “We believe that this problem in Stamford could reach much further than Stamford itself and it could exist even beyond Fairfield County.”
Stamford Health Director Anne Fountain remarked, “As you can see, one house may have it and the one next door may not. This is happening in Stamford and I don’t think it stops at the borders.” Around 2.3 million people in New England get their water from private wells, and most all do not require pesticide testing before use due to its cost. Protect your family and have your CT well water tested by a qualified professional if you suspect contamination.
