In which year was the Clean Water Act enacted?

The Clean Water Act was enacted in 1972, and this legislation was significant in setting the foundation for regulating pollutant discharges into the waters of the United States. Its primary goals were to restore and maintain the integrity of the nation's waters by preventing point and nonpoint source pollution, ensuring that water quality standards were met, and protecting the aquatic ecosystems. The Act has led to substantial improvements in water quality across the country. The years before and after 1972 did not have this specific comprehensive federal effort aimed at water quality protection, which is why 1972 is the pivotal year related to the Clean Water Act.
