The maximum reported level of HAA5 (five regulated haloacetic acids) was 2.6 µg/L. The maximum reported level of Manganese was 1590 µg/L. Some (1 of 22 or 5%) 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 Grandview 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.
