The text primarily uses a chronological organizational structure. It outlines the progression of events leading to the passage of the Clean Water Act of 1972, starting with the environmental issues in the 1960s and leading to the actions taken to address those issues. The emphasis on historical context and the sequence of events demonstrates a timeline of the water pollution crisis and the subsequent legislative response.
Congress passed the Clean Water Act of 1972 to address the serious environmental crisis of water pollution. In New York's Hudson River, levels of toxic bacteria were 170 times the level considered safe. Oil floating on the the Cuyahoga River near Cleveland, Ohio, burst into flames in 1969. Factories were dumping pollutants into waterways, untreated sewage flowed directly into rivers, and untold numbers of fish were dying. The Clean Water Act restricted discharges of pollution into the nation's waters and authorized the Environmental Protection Agency to enforce water quality regulations. It also provided money for sewage treatment plants. Although the work to clean up the nation's lakes and streams is ongoing, water quality today is much better than it was in the 1960s.
