Lead and Copper in Drinking Water

Lead and copper are metals commonly used in household plumbing. The lead and copper rule has forced community and non-transient, non-community water systems to conduct tests to determine if lead and copper are present in high levels at the consumer's tap. The Lead and Copper Rule defines the acceptable limits (action levels) for lead and copper in drinking water. The action level for copper is 1.3 milligrams per liter (mg/L). The action level for lead is 0.015 mg/L.
