What legislation regulates drinking water quality standards?

The Safe Drinking Water Act is the legislation that specifically regulates drinking water quality standards in the United States. Enacted in 1974, this act aims to protect public health by ensuring that municipal water systems provide safe drinking water. The law allows the Environmental Protection Agency (EPA) to set national standards for drinking water, which includes limits on contaminants and requirements for water treatment processes.

This legislation is crucial because it establishes the framework for water quality monitoring and the implementation of safety standards that all public water systems must meet. It focuses on the protection of drinking water sources and mandates actions to assist states and water systems in achieving those standards, thus safeguarding public health and ensuring access to safe drinking water.

While the other legislation mentioned focuses on various aspects of water quality and environmental health, none of them are specifically concerned with the quality standards for drinking water as outlined in the Safe Drinking Water Act.
