Passed in 1972, The Clean Water Act (CWA) is the cornerstone of surface water quality protection in the United States. While the Act does not address ground water or water quantity issues, it is aimed at reducing the direct pollution of waterways by financing wastewater treatment plants and by managing polluted runoff. The goal is to restore and maintain the chemical, physical, and biological integrity of the nation’s waters for “the protection and propagation of fish, shellfish, wildlife and recreation in and on the water.”
When the CWA was first enacted, regulation was directed at the chemical aspects of the “integrity” goal. Since then, more attention has been given to physical and biological integrity. Initially, “point source” facilities such as sewage plants and industrial developments were the focus, with little notice given to runoff from streets, construction sites, and other “wet-weather” sources. Since the 1980s, added regulations and various voluntary programs have been adopted to significantly reduce polluted runoff.
Additionally, CWA programs over the last decade have shifted to a watershed-based strategy. Now, equal emphasis is placed on protecting healthy waters and restoring impaired ones. A wide array of issues is addressed, and various stakeholders are included in development and implementation of strategies for improving state water quality.
In order for businesses to comply with regulatory authorities, runoff, or outfall sources must be monitored. Neilson Research Corporation can help you meet these requirements by providing sample containers, technique, and instructions for proper documentation.
