North Liberty Water Supply (IA) Water Quality

North Liberty Water Supply is a large public water system in EPA region 7 that provides tap water for the 52317 zip codes. It has 5 facilities where the water supply was tested for 50 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 0.36 µg/L. The maximum reported level of Manganese was 15 µg/L. The maximum reported level of quinoline was 0.032 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 North Liberty Water Supply 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.
