Chester Water Authority (PA) Water Quality

Chester Water Authority is a large public water system in EPA region 3 that provides tap water for the 19013 - 19017, 19061, 19064, 19311, 19312, 19319, 19331, 19340, 19343, 19348, 19352, 19357, 19362, 19363, 19373, 19374, 19382 zip codes. It has 3 facilities where the water supply was tested for 85 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 65.4 µg/L. Some (2 of 32 or 6%) of the latest water samples showed levels of HAA5 (five regulated haloacetic acids) that were at or above unsafe concentration levels. The maximum reported level of Manganese was 4.26 µg/L. There were 2 contamintants found in the Chester Water Authority 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.
