Swansea Water District (MA) Water Quality

Swansea Water District is a large public water system in EPA region 1 that provides tap water for the 02777 zip codes. It has 19 facilities where the water supply was tested for 78 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 67.8 µg/L. Some (1 of 16 or 6%) of the latest water samples showed levels of HAA5 (five regulated haloacetic acids) that were at or above unsafe concentration levels. The maximum reported level of Manganese was 1490 µg/L. Some (3 of 14 or 21%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Swansea Water District water supply at levels that were above the minimum reporting level. 2 of the contaminants were above the reference level, which means they may pose a risk to human health.
