Federal Water Pollution Control Act (Clean Water Act)

The Clean Water Act (CWA) employs a variety of regulatory and non-regulatory tools to reduce direct pollutant discharges into the nation's waterways, finance wastewater treatment facilities, and manage polluted runoff. It also gives EPA the authority to implement pollution control programs and to set wastewater standards for industry and limitations on contaminants in surface waters. The broader goal of the Act is to help restore and maintain the chemical, biological, and physical integrity of the nation's waters. The watershed based strategies in the Act have evolved to give equal emphasis to protecting healthy waters and restoring impaired ones. They also encourage the involvement of stakeholder groups in strategies for maintaining water quality and security.
