City of Zachary Water (LA) Water Quality

City of Zachary Water is a large public water system in EPA region 6 that provides tap water for the 70791 zip codes. It has 11 facilities where the water supply was tested for 68 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 3.94 µg/L. The maximum reported level of Manganese was 23.3 µg/L. The maximum reported level of quinoline was 0.0864 µg/L. Some (4 of 10 or 40%) of the latest water samples showed levels of quinoline that were at or above unsafe concentration levels. There were 3 contamintants found in the City of Zachary Water 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.
