Which law started in 1972 and regulates water pollution in the United States?

• A. Water Quality Act
• B. Clean Water Act
• C. Clean Drinking Water Act
• D. Primary Sewage Treatment

Answer: (B)

The main idea here is how the U.S. sets nationwide rules to prevent and control water pollution. In 1972, Congress passed the Clean Water Act, a landmark law that created a comprehensive framework for regulating discharges into waters of the United States. It introduced the permit system known as the National Pollutant Discharge Elimination System (NPDES), so that any discharge from a point source into rivers, lakes, or coastal waters must meet approved limits. It also pushed for upgrading wastewater treatment and establishing consistent water quality standards across states, with the goal of restoring and maintaining the chemical, physical, and biological integrity of surface waters. Other choices don’t fit because the Water Quality Act was enacted earlier (in the 1960s) and did not establish the modern permit-based approach. The term Clean Drinking Water Act isn’t the actual law; drinking water standards are covered by the Safe Drinking Water Act (1974), which focuses on drinking water supplies rather than pollution in all surface waters. Primary sewage treatment describes a treatment process rather than a law.
