Which US environmental law requires corrosion control for municipal drinking water?

The Safe Drinking Water Act is the US environmental law that primarily focuses on ensuring the quality of drinking water in the United States. This act requires the establishment of national standards to protect public health from contaminants in drinking water, including provisions for corrosion control.

Corrosion control is critical because if water systems are not properly managed, lead and copper can leach from pipes and fixtures into drinking water, posing severe health risks. The Safe Drinking Water Act not only sets these protections but also mandates that water suppliers take measures to mitigate such risks, which includes implementing corrosion control strategies to minimize leaching.

Other laws, while they may address environmental concerns, do not specifically focus on the quality and safety of municipal drinking water in the same capacity as the Safe Drinking Water Act. For example, the Clean Water Act is essential for regulating discharges into waterways, while the National Environmental Policy Act centers around environmental impact assessments. The Lead-Copper Rule, although directly related to lead and copper contamination, is actually a part of the regulatory framework established under the Safe Drinking Water Act rather than a separate law.
