The EPA additionally regulates wastewater, but under the requirements of the Clean Water Act (CWA). Storm water and discharges into surface water are also regulated under the CWA. The SDWA sets maximum contaminant levels (MCLs) and treatment techniques (TTs) that drinking water must meet to be considered safe for consumption. The list includes microorganisms, disinfectants and disinfection by-products, inorganic chemicals, organic chemicals, and radionuclides. Safe Drinking Water Act (SDWA) The Safe Drinking Water Act (SDWA) is the main federal law that ensures the quality of Americans’ drinking water. Under SDWA, EPA sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards. SDWA was originally passed by Congress in 1974 to protect public health by regulating the nation’s public drinking water supply. The law was amended in 1986 and 1996 and requires many actions to protect drinking water and its sources: rivers, lakes, reservoirs, springs, and ground water wells. (SDWA does not regulate private wells which serve fewer than 25 individuals.) National Primary Drinking Water Regulations National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water. Clean Air Act Results For more than forty years, the Clean Air Act has cut pollution as the U.S. economy has grown. Experience with the Clean Air Act since 1970 has shown that protecting public health and building the economy can go hand in hand. Clean Air Act programs have lowered levels of six common pollutants — particles, ozone, lead, carbon monoxide, nitrogen dioxide and sulfur dioxide — as well as numerous toxic pollutants.
