UNH - Durham Water (NH) Water Quality

UNH - Durham Water is a large public water system in EPA region 1 that provides tap water for the 03824 zip codes. It has 8 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 49.6 µg/L. The maximum reported level of Manganese was 157 µg/L. The maximum reported level of quinoline was 0.125 µg/L. Some (1 of 6 or 17%) of the latest water samples showed levels of quinoline that were at or above unsafe concentration levels. There were 3 contamintants found in the UNH - Durham Water 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.
