Safe Drinking Water Act (SDWA): A Summary of the Act and Its Major Requirements [March 1, 2017] [open pdf - 931KB]
"This report summarizes the Safe Drinking Water Act (SDWA) and its major programs and regulatory requirements. […] The SDWA, Title XIV of the Public Health Service Act, is the key federal law for protecting public water supplies from harmful contaminants. First enacted in 1974 and substantially amended and reauthorized in 1986 and 1996, the act is administered through programs that establish standards and treatment requirements for public water supplies, promote compliance capacity of public water systems, provide technical assistance to small water systems, control the underground injection of fluids, finance infrastructure projects, and protect sources of drinking water. The 1974 law established the current federal-state arrangement in which states may be delegated primary implementation and enforcement authority (primacy) for the drinking water program and the underground injection control (UIC) program. The state-administered Public Water Supply Supervision (PWSS) Program remains the basic program for regulating the nation's public water systems, and 49 states have assumed this authority. In the Safe Drinking Water Act Amendments of 1996, Congress reauthorized appropriations for most SDWA programs through FY2003. As with other EPA-administered statutes having expired funding authority, Congress has continued to appropriate funds for the ongoing SDWA programs. In addition to reviewing key programs and requirements of the SDWA, this report includes statistics on the number and types of regulated public water systems and lists all major amendments with the year of enactment and public law number."
