Regional Water Authority (CT) Water Quality

Regional Water Authority is a large public water system in EPA region 1 that provides tap water for the 06401, 06408, 06418, 06461, 06471 - 06473, 06483, 06502 - 06521, 06525, 06531 - 06538, 06716 zip codes. It has 19 facilities where the water supply was tested for 85 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 41 µg/L. The maximum reported level of Manganese was 2280 µg/L. Some (1 of 30 or 3%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Regional Water Authority 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.
