Stillwater Water Plant (OK) Water Quality

Stillwater Water Plant is a large public water system in EPA region 6 that provides tap water for the 74074 zip codes. It has 5 facilities where the water supply was tested for 78 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 45.858 µg/L. The maximum reported level of Manganese was 0.89 µg/L. The maximum reported level of quinoline was 0.05318 µg/L. Some (1 of 4 or 25%) of the latest water samples showed levels of quinoline that were at or above unsafe concentration levels. There were 3 contamintants found in the Stillwater Water 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.
