Central ASG (AS) Water Quality

Central ASG is a large public water system in EPA region 9 that provides tap water for the 96799 zip codes. It has 42 facilities where the water supply was tested for 65 chemical contaminants that impact tap water quality and human health.

The maximum reported level of Manganese was 480 µg/L. Some (1 of 61 or 2%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 1 contamintants found in the Central ASG 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.
