Arapahoe County WWWA (CO) Water Quality

Arapahoe County WWWA is a large public water system in EPA region 8 that provides tap water for the 80015, 80016, 80112 zip codes. It has 21 facilities where the water supply was tested for 65 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 16.6 µg/L. The maximum reported level of Manganese was 764 µg/L. Some (4 of 18 or 22%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Arapahoe County WWWA 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.
