The Clean Water Act established the structure for regulating pollutants in U.S. waterways and regulating quality standards for surface waters. The basis of the Clean Water Act was enacted in 1948; however, growing public awareness and concern for controlling water pollution led to sweeping amendments in 1972.

  •   Established the basic structure for regulating pollutant discharges.
  •   Gave EPA the authority to implement pollution control programs.
  •   Maintained existing requirements to set water quality standards for all contaminants in surface waters.
  •   Made it unlawful to discharge any pollutant from a point source into navigable waters, unless a permit was obtained under its provisions.
  •   Funded the construction of sewage treatment plants under the construction grants program.
  •   Recognized the need for planning to address the critical problems posed by nonpoint source pollution.

As such an important piece of legislation, the CWA provides citizens the right to waterways that are clean, biologically intact, and safe for use, and includes an array of protections and programs to reach that goal. For more information, please visit the California Water Boards or the Environmental Protection Agency (EPA) website.
