Safe Drinking Water Act and Regulations (EPA)

You are here

Congress enacted the Safe Drinking Water Act (SDWA) in 1974 and amended and reauthorized it in 1986 and 1996. It is the main federal law that ensures the quality of Americans' drinking water. The SDWA authorizes the U.S. Environmental Protection Agency (EPA) to set national standards for drinking water to protect against health effects from exposure to naturally-occurring and man-made contaminants.

For more information, including copies of the SDWA and EPA's implementing regulations, see EPA's Safe Drinking Water Act home page.
