Safe Drinking Water Act (SDWA)
Safe Drinking Water Act
The Safe Drinking Water Act (SDWA) was originally passed by Congress in 1974 to protect public health by regulating the nation’s public drinking water supply. Read the SDWA Overview.
Protecting America’s drinking water is a top priority for EPA. EPA has established protective drinking water standards for more than 90 contaminants, including drinking water regulations issued since the 1996 amendments to the Safe Drinking Water Act that strengthen public health protection. Over 92 percent of the population supplied by community water systems receives drinking water that meets all health-based standards all of the time.
