What is the main purpose of the lead and copper rule (LCR)?

The main purpose of the Lead and Copper Rule (LCR) is to minimize lead and copper levels in drinking water. The LCR was established to protect public health by addressing the risks associated with these metals, which can leach into drinking water primarily from corroding pipes and plumbing fixtures. Exposure to lead, even at low levels, can lead to serious health effects, particularly in vulnerable populations such as children and pregnant women. Copper, while essential in small amounts, can also be harmful at elevated levels.

By setting action levels for lead and copper concentration, the LCR requires water systems to monitor and reduce these contaminants, ensuring that drinking water remains safe and that the public is informed about their water quality. This regulation plays a critical role in preventing potential health hazards associated with lead and copper exposure.
