Parker WSD (CO) Water Quality

Parker WSD is a large public water system in EPA region 8 that provides tap water for the 80108, 80124, 80138 zip codes. It has 43 facilities where the water supply was tested for 78 chemical contaminants that impact tap water quality and human health.

The maximum reported level of 1-butanol was 2.89 µg/L. The maximum reported level of alpha-hexachlorocyclohexane was 0.022 µg/L. Some (1 of 18 or 6%) of the latest water samples showed levels of alpha-hexachlorocyclohexane that were at or above unsafe concentration levels. The maximum reported level of HAA5 (five regulated haloacetic acids) was 8.94 µg/L. The maximum reported level of Manganese was 76.3 µg/L. There were 4 contamintants found in the Parker WSD 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.
