Drinking Water
National Summary
Drinking water in the United States is regulated under the Safe Drinking Water Act (SDWA), which is designed to protect drinking water quality and covers both surface and groundwaters that have the potential to be used as drinking water sources. The U.S. Environmental Protection Agency (EPA) has the authority to establish and update specific standards for drinking water quality and is supported by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA).
