What is Lead?

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.

Water suppliers

Lead value per supplier, LCR compliance samples. EPA action level — 0.015 mg/L at the 90th percentile. Suppliers that exceeded the lead action level are highlighted and listed first. “Not detected” means the contaminant was measured but not found.
