MAWC - Yough Plant (PA) Water Quality

MAWC - Yough Plant is a large public water system in EPA region 3 that provides tap water for the 15012, 15033, 15083, 15473, 15601, 15619, 15625, 15637, 15640, 15650, 15666, 15672, 15678, 15679, 15693, 15697, 15698 zip codes. It has 4 facilities where the water supply was tested for 85 chemical contaminants that impact tap water quality and human health.

The maximum reported level of 1-butanol was 14 µg/L. The maximum reported level of HAA5 (five regulated haloacetic acids) was 78.8 µg/L. Some (3 of 31 or 10%) 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 67.6 µg/L. There were 3 contamintants found in the MAWC - Yough Plant 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.
