East Lyme Water & Sewer Commission (CT) Water Quality

East Lyme Water & Sewer Commission is a large public water system in EPA region 1 that provides tap water for the 06333 zip codes. It has 17 facilities where the water supply was tested for 69 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 3.6 µg/L. The maximum reported level of Manganese was 828 µg/L. Some (3 of 13 or 23%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the East Lyme Water & Sewer Commission water supply at levels that were above the minimum reporting level. 1 of the contaminants were above the reference level, which means they may pose a risk to human health.
