S. 2770, Federal Water Pollution Control Act Amendments of 1972

The Federal Water Pollution Control Act of 1972, introduced by Senator Edmund S. Muskie of Maine, reorganized and expanded earlier legislation regulating surface-water quality. It required federal permits for release of pollutants into the nation’s waters. Congress had to balance the financial costs to businesses and farmers with the health and environmental costs of pollution.

"The objective of this Act is to restore and maintain the natural chemical, physical, and biological integrity of the Nation’s waters."
