Which agency is primarily responsible for establishing wastewater regulations in the United States?

The agency that is primarily responsible for establishing wastewater regulations in the United States is the Environmental Protection Agency (EPA). The EPA was created to protect human health and the environment by enforcing regulations based on laws passed by Congress. Specifically, the Clean Water Act is one of the key pieces of legislation that governs the discharge of pollutants into waters, and the EPA sets standards for wastewater treatment and quality.

The role of the EPA encompasses developing and enforcing regulations related to water quality, providing guidance for industry practices, and issuing permits for wastewater discharges. This ensures that wastewater is treated to remove contaminants before it is released back into the environment, thereby safeguarding ecosystems and public health.

Other agencies mentioned have different focuses; for example, the Environmental Defense Fund works on advocacy and policy, the Centers for Disease Control and Prevention primarily focuses on public health issues, and the United States Geological Survey conducts scientific research related to natural resources and hazards. While these organizations may contribute to environmental protection or public health, they do not have the same regulatory authority over wastewater as the EPA.
