The maximum reported level of HAA5 (five regulated haloacetic acids) was 68.5 µg/L. Some (3 of 16 or 19%) of the latest water samples showed levels of HAA5 (five regulated haloacetic acids) that were at or above unsafe concentration levels. The maximum reported level of Manganese was 1120 µg/L. Some (1 of 4 or 25%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the City of Cayce water supply at levels that were above the minimum reporting level. 2 of the contaminants were above the reference level, which means they may pose a risk to human health.
