Swampscott Water Dept. (MA) Water Quality

Swampscott Water Dept. is a large public water system in EPA region 1 that provides tap water for the 01907 zip codes. It has 3 facilities where the water supply was tested for 68 chemical contaminants that impact tap water quality and human health.

The maximum reported level of 1-butanol was 8.16 µg/L. The maximum reported level of HAA5 (five regulated haloacetic acids) was 13.858 µg/L. The maximum reported level of Manganese was 6.36 µg/L. The maximum reported level of quinoline was 0.0282 µg/L. Some (1 of 4 or 25%) of the latest water samples showed levels of quinoline that were at or above unsafe concentration levels. There were 4 contamintants found in the Swampscott Water Dept. 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.
