The Lead and Copper Rule was promugulated by the U.S. EPA in 1991 to limit the concentration of lead and copper in public drinking water at the consumer's tap. The Lead and Copper rule places the responibilty to minimize corrosion of lead and copper service lines in the hands of the drinking water provider. As a result, a water treatment ulility must test the lead and copper concentration at a point of use location, and add corrosion inhibiting chemicals to the water to ensure complience.

The maximum contaminant level goal under the Lead and Copper Rule is 0 mg/L for Lead, and 1.3 mg/L of Copper.
