What were the main aims of the Clean Water Act of 1972?

• A. Removed federal controls on water pollution
• B. Regulated discharges of pollutants into navigable waters; aimed to restore and maintain water quality
• C. Only regulated drinking water standards
• D. Abolished the authority to regulate discharge permits

Answer: (B)

The main idea behind the Clean Water Act is to protect and improve the quality of the nation’s waterways by controlling pollution at its source and setting standards for water quality. It accomplishes this by creating a national permit system that requires anyone discharging pollutants into navigable waters to meet specific limits, ensuring that what goes into rivers, lakes, and coastal areas is regulated. At the same time, it establishes broad goals to restore waters that are impaired and to maintain high water quality going forward, guiding cleanup efforts and investments in wastewater treatment. This combination—regulating discharges and aiming to restore and maintain water quality—captures the Act’s purpose really well. It also helps explain why other options don’t fit: the Act expanded federal control rather than removed it, it addresses more than drinking water standards, and it did not abolish permit authority—in fact, it created and strengthened it.
