North Wales Water Authority (PA) Water Quality

North Wales Water Authority is a large public water system in EPA region 3 that provides tap water for the 18914, 18915, 18976, 19034, 19436, 19437, 19446, 19477, 19490 zip codes. It has 13 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 38.371 µg/L. The maximum reported level of Manganese was 336 µg/L. Some (1 of 22 or 5%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the North Wales 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.
