Hampton Bays Water District (NY) Water Quality

Hampton Bays Water District is a large public water system in EPA region 2 that provides tap water for the 11946 zip codes. It has 12 facilities where the water supply was tested for 75 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 1.38 µg/L. The maximum reported level of Manganese was 419 µg/L. Some (1 of 10 or 10%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Hampton Bays Water District 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.
