Congress Amends the Water Pollution Control Act.

The U.S. Congress passed the amended Water Pollution Control Act on June 27, 1956, three days before the 1948 version of the act was due to expire, and President Dwight D. Eisenhower signed it into law on July 9, 1956. It was thought that the act would enable the nation to produce the huge quantities of clean, fresh water needed by the ever-increasing national population and its giant industrial complex.
