Cotto Laurel (PR) Water Quality

Cotto Laurel is a large public water system in EPA region 2 that provides tap water for the 00733 zip codes. It has 14 facilities where the water supply was tested for 78 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 66.62 µg/L. Some (1 of 24 or 4%) 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 0.624 µg/L. There were 2 contamintants found in the Cotto Laurel 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.
