This past October marked the 35th anniversary of the U.S. Environmental Protection Agency’s (EPA) Clean Water Act. This legislation certainly changed the landscape for national water quality issues by establishing a basic structure for regulating discharges of pollutants into U.S. waters and giving the EPA authority to implement pollution control programs. The act also continued requirements to set water quality standards for all contaminants in surface waters.
