History

Historical Context

The Clean Water Act of 1972 aimed to eliminate water pollution in the U.S. by mandating upgrades to sewage systems, with Congress authorizing $24.6 billion for improvements. Despite these efforts, over 1 trillion gallons of untreated sewage are still released annually, as highlighted by recent discharges into the Potomac River.
