What agency governs drinking water regulations in the United States?

The agency that governs drinking water regulations in the United States is the United States Environmental Protection Agency (USEPA). The USEPA is responsible for ensuring that the nation's drinking water supply meets established safety standards as outlined in the Safe Drinking Water Act. This act empowers the agency to set national health-based standards for drinking water to protect against both natural and man-made contaminants.

The USEPA conducts research and provides guidance to states and local water systems regarding water quality, treatment processes, and pollution prevention strategies. Their role includes monitoring compliance with regulations and offering support for infrastructure improvements in public water systems. This is critical for maintaining public health and ensuring safe drinking water access.

In contrast, other agencies like the CDC focus primarily on public health issues and disease prevention, OSHA is concerned with workplace safety, and the FDA regulates food and drugs, but does not have the primary responsibility for drinking water regulations. Each of these agencies plays significant roles in public health and safety, but when it comes specifically to drinking water, the USEPA is the central governing body.
