The Safe Water Act of 1974, 1984, and 1996 • Alejandro Lopez-High • Per. 5
SDWA • The Safe Drinking Water Act (SDWA) is the main federal law that ensures the quality of Americans' drinking water. Originally passed by Congress in 1974 to protect public health by regulating the nation's public drinking water supply, the act created two major initiatives. • The first allowed the United States Environmental Protection Agency (USEPA) to set enforceable standards for health-related drinking water contaminants for all public water supplies. • The second gave the USEPA responsibility for developing a broad ground water protection program known as the Underground Injection Control (UIC) program (Bedient et. al., 1994).
Amendments • The Hazardous and Solid Waste Amendments of 1984 prohibited land deposition of hazardous waste, including injection into wells. • A major set of amendments was added to the SDWA in 1986 due to congressional concerns that the USEPA was not developing MCLs at an acceptable rate. One of the most important requirements of the amendments is that USEPA must develop 25 new MCLs every three years. The amendments also required the USEPA to specify criteria under which filtration would be mandatory for water supplies with surface water sources.
