City of Poulsbo (WA) Water Quality

City of Poulsbo is a large public water system in EPA region 10 that provides tap water for the 98370 zip codes. It has 8 facilities where the water supply was tested for 65 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 3.4 µg/L. The maximum reported level of Manganese was 1178 µg/L. Some (1 of 12 or 8%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the City of Poulsbo 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.
