Ipswich DPU Water Dept. (MA) Water Quality

Ipswich DPU Water Dept. is a large public water system in EPA region 1 that provides tap water for the 01938 zip codes. It has 16 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 19.854 µg/L. The maximum reported level of Manganese was 657 µg/L. Some (4 of 14 or 29%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Ipswich DPU 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.
