Which agency is responsible for protecting our waterways from contamination?

The Environmental Protection Agency (EPA) is the agency responsible for protecting our waterways from contamination. It was established to oversee and enforce the country's environmental laws, focusing on protecting human health and the environment. The EPA implements regulations to control pollution in the nation’s rivers, streams, lakes, and other bodies of water, ensuring that they are safe for drinking and recreational activities. Among its various responsibilities, the agency administers the Clean Water Act, which aims to restore and maintain the integrity of the nation's waters.

The other agencies listed have distinct functions: OSHA (Occupational Safety and Health Administration) focuses on workplace safety and health; the FDA (Food and Drug Administration) regulates food safety and pharmaceuticals; and PHS (Public Health Service) provides health programs and services but does not specifically target waterway protection. Understanding the specific roles of these agencies clarifies why the EPA is the most relevant choice for this question about protecting waterways.
