![Mary Workman holds a jar of undrinkable water that comes from her well, and has filed a damage suit against the Hanna Coal Company, Steubenville (Jefferson county, Ohio), 1973. In 1974, Congress passes the Safe Drinking Water Act, allowing EPA to regulate the quality of public drinking water. SDWA is the primary regulatory framework for setting and enforcing national standards for drinking water quality. Today, the EPA has drinking water regulations for more than 90 contaminants, including microorganisms, disinfectants, disinfection byproducts, inorganic and organic chemicals, and radionuclides. Individual rules apply to different water systems based on type of system, source water type, installed treatment, population served, and other factors. 2014 marks the 40th anniversary of the law.
