Which regulatory agency oversees public drinking water systems in the United States?

The Environmental Protection Agency (EPA) is the regulatory agency responsible for overseeing public drinking water systems in the United States. The agency administers and enforces the Safe Drinking Water Act, which sets health standards for drinking water quality. This legislation empowers the EPA to regulate the nation's public water systems to ensure that the drinking water is safe for consumption and free from harmful contaminants.

The EPA's role includes establishing maximum contaminant levels, monitoring water quality, and providing guidance and resources to water systems across the country. Their oversight is crucial for protecting public health and ensuring that communities have access to safe and reliable drinking water.

In contrast, the Food and Drug Administration (FDA) primarily regulates food products and bottled water but does not oversee public drinking water systems. The Centers for Disease Control and Prevention (CDC) focuses on public health and disease control, providing information on waterborne illnesses and promoting safe water practices rather than regulating water systems. The Occupational Safety and Health Administration (OSHA) deals with workplace safety and health regulations, which does not include the oversight of public drinking water systems.
