Portage (MI) Water Quality

Portage is a large public water system in EPA region 5 that provides tap water for the 49002, 49048 zip codes. It has 18 facilities where the water supply was tested for 75 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 3.49 µg/L. The maximum reported level of Manganese was 352.46 µg/L. Some (4 of 20 or 20%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Portage 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.
