Which federal agency plays a key role in regulating the water utility industry?

The Environmental Protection Agency, or EPA, is the federal agency primarily responsible for regulating the water utility industry. Its mission includes safeguarding the nation's waters by enforcing regulations established under various laws, including the Clean Water Act and the Safe Drinking Water Act. The EPA's role involves setting standards for water quality, ensuring that drinking water is safe for consumption, and managing the protection and restoration of water bodies.

The agency conducts research and provides guidelines to state and local governments, helping them to implement effective water management practices. It also oversees the National Pollutant Discharge Elimination System (NPDES), which regulates discharges of pollutants into water sources. By setting these regulations and standards, the EPA plays a critical role in ensuring the safety and quality of water provided by utilities across the country, thereby protecting public health and the environment.

Other agencies, such as the FDA, CDC, and USDA, have significant roles in health, food safety, and agricultural practices but do not specifically focus on the regulation of water utilities like the EPA does.
