Who is responsible for enforcing the Lead and Copper Rule in drinking water systems?

1. Local water municipalities

2. State Water Resources Control Board

3. U.S. Environmental Protection Agency

4. Environmental Health Departments

The correct answer is: State Water Resources Control Board

The responsibility for enforcing the Lead and Copper Rule in drinking water systems falls to the State Water Resources Control Board. This regulation aims to reduce lead and copper levels in drinking water to protect public health. The State Water Boards are tasked with overseeing the implementation of the standards set forth by the U.S. Environmental Protection Agency at the state level. While local water municipalities play a role in monitoring and maintaining drinking water quality, they operate under the guidelines set by the state boards. The U.S. Environmental Protection Agency establishes national standards, but its enforcement at the local level is primarily executed through state agencies. The Environmental Health Departments are typically involved in public health aspects related to drinking water but do not have direct enforcement authority over the Lead and Copper Rule specifically. Thus, the State Water Resources Control Board serves as the key entity responsible for ensuring compliance with this important regulation, safeguarding public health by managing lead and copper levels in drinking water systems.
