Lead in MP drinking water

36 community water systems tested

5.6%
of tested systems exceeded the lead action level
(2/36)

Lead is a neurotoxin with no known safe level. It usually enters water from old service lines and household plumbing rather than the source, so results vary system to system. The EPA acts when the 90th-percentile sample exceeds 0.015 mg/L.
