Which agency is responsible for ensuring clean air and water?

The agency responsible for ensuring clean air and water is the Environmental Protection Agency (EPA). The EPA was established to protect human health and the environment by enforcing regulations based on laws passed by Congress. It plays a crucial role in regulating pollutants and establishing standards for air and water quality, ensuring that these vital resources remain safe and accessible to the public.

The agency implements policies aimed at reducing environmental risks stemming from toxic substances, waste disposal, and other environmental hazards. Additionally, the EPA conducts research and provides education on environmental issues, further emphasizing its commitment to maintaining a healthy environment.

In contrast, the other options do not have the primary mandate of regulating air and water quality. The Department of Labor focuses on occupational safety and workforce regulations, while the Food and Drug Administration oversees food safety and pharmaceutical regulation. The Centers for Disease Control and Prevention is primarily concerned with public health and disease control rather than environmental standards related to air and water.
