Which organization is responsible for regulating drinking water quality in the U.S.?

The Environmental Protection Agency (EPA) is indeed the organization responsible for regulating drinking water quality in the U.S. The EPA enforces the Safe Drinking Water Act, which sets standards for drinking water quality and oversees states, localities, and water suppliers to ensure compliance. The agency's role includes monitoring contaminant levels, establishing water quality criteria, and ensuring public water systems meet regulatory requirements to protect public health.

Other organizations listed have distinct roles but do not directly regulate drinking water quality. For example, the FDA oversees food safety and bottled water but does not manage municipal drinking water systems. The CDC focuses on public health and disease prevention but does not have regulatory authority over drinking water. Meanwhile, OSHA primarily deals with workplace safety and health standards rather than water quality. Thus, the EPA's regulatory framework is crucial for maintaining safe and clean drinking water across the nation.
