technology based law
Clean Water Act
(1948): Federal Water Pollution Control Act in affect
(1972): Amendments made to Federal Water Pollution Control Act
(1977): Became formally known as Clean Water Act
The Clean Water Act regulates discharges of pollutants into water in the United States and sets quality standards for contaminants in surface waters.
CWA made it unlawful to discharge pollutants into navigable waterways unless a permit is obtained.
Because the Industrial plants were the main cause of the waste in the water, the law was directed mainly towards them. The government granted billions of dollars to industries to improve their water filtration systems.
