What regulation is aimed at controlling lead and copper levels in drinking water?

The correct response is the Lead and Copper Rule, which is specifically designed to control lead and copper levels in drinking water supplies. This regulation was established under the Safe Drinking Water Act and is crucial for protecting public health by limiting the amount of these metals that can leach into drinking water from plumbing systems, particularly in older homes and buildings with lead pipes or solder.

The Lead and Copper Rule mandates regular monitoring of water quality and requires water systems to take action if lead or copper levels exceed designated thresholds. This includes public education initiatives and the replacement of lead service lines to reduce exposure risks.

While the Safe Drinking Water Act establishes the framework for regulating drinking water quality as a whole, the Lead and Copper Rule specifically addresses the hazards posed by lead and copper, making it the most direct regulation concerning these particular contaminants.
