The Clean Water Act of 1972

As the 20th century progressed, more and more metropolitan areas in the world found it necessary to install water treatment plants in order to provide clean, healthy water to their residents. It became a general principle in the developed world that every person had the right to clean, pure water. There was no universal standard or definition for clean, pure water. Many city officials, as they noted the disinfecting power of chlorine, believed that providing disinfected, yet untreated, water to city residents was their only responsibility.

Environmental concerns rose in the United States in the 1960s and 1970s that would greatly affect the definition of clean, pure water and the responsibility of the government to provide such water. In the early 1970s, environmental lobbyists in the United States began to see results in their fight for the environment. Multiple environmental acts passed through Congress in rapid succession, including the formation of Earth Day as a national holiday, the formation of the Environmental Protection Agency (EPA), the passage of the Clean Air Act, and, most important to the history of water filters, the passage of the Clean Water Act of 1972 (Outwater, 1996).

The Clean Water Act, like the discovery of the microscope and the disastrous effects of cholera and typhoid epidemics throughout the world, sparked renewed interest in water filtration. It became law that every city in the nation install a water treatment plant, and it became a national goal to have clean water, once more, by 1985 (Outwater, 1996).

Because industrial waste was viewed as the main culprit of contaminated water, industrial plants were the main targets of the law. Over the next few decades, the U.S. government expended billions of dollars in grants to industries to create environment-friendly waste management techniques. Cities were also given grant money to install water treatment plants. Eventually, the sludge in the rivers and water supplies of the nation began to disappear.
