The maximum reported level of HAA5 (five regulated haloacetic acids) was 1.27 µg/L. The maximum reported level of Manganese was 9.4 µg/L. The maximum reported level of quinoline was 0.029 µg/L. Some (1 of 10 or 10%) of the latest water samples showed levels of quinoline that were at or above unsafe concentration levels. There were 3 contamintants found in the Golden State Water Company - South Arcadia 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.
