Lead and Copper
Informational Links Regarding Their Effects on Drinking Water and You
The purpose of the Lead and Copper Rule (LCR) is to protect public health by minimizing lead and copper levels in drinking water, primarily by reducing corrosivity. Lead and copper enter drinking water mainly from corrosion of lead and copper containing plumbing materials. The rule establishes an action level (AL) of 0.015 milligrams per liter (mg/L) for lead and 1.3 mg/L for copper based on 90th percentile level of tap water samples. An action level exceedance is not a violation but triggers other requirements to minimize exposure to lead and copper in drinking water, that include water quality parameter monitoring, corrosion control treatment, source water monitoring/treatment, public education, and lead service line replacement. All community water supplies and nontransient noncommunity water supplies are subject to the LCR requirements.
