Which federal organization is responsible for enforcing regulations on air and water pollution?

The Environmental Protection Agency (EPA) is responsible for enforcing regulations related to air and water pollution. This federal agency plays a crucial role in protecting human health and the environment by setting and enforcing standards that limit pollutants in the air and water. The EPA conducts research, monitors environmental quality, and administers various environmental laws aimed at preserving natural resources and ensuring clean air and water for the public.

In contrast, the other organizations listed have different mandates. The Federal Trade Commission focuses on consumer protection and preventing anticompetitive business practices. The Occupational Safety and Health Administration is concerned with ensuring workplace safety and health standards. The Department of Health and Human Services deals primarily with public health and social services, not directly with environmental pollution regulations. These distinctions clarify why the Environmental Protection Agency is the appropriate choice in this context.
