The Lead and Copper Rule

The Lead and Copper Rule is a regulation in the United States designed to protect drinking water from harmful levels of lead and copper. Established by the Environmental Protection Agency (EPA), it sets limits on the amounts of these metals allowed in public water systems. If lead or copper levels exceed these limits, water systems must take action to reduce them, such as adjusting water chemistry or replacing old pipes. The rule aims to minimize health risks, especially for children and pregnant women, who are particularly vulnerable to the negative effects of these contaminants.
