This report looks at ways which the 112th Congress can introduce legislation to safeguard water quality in the U.S., and reasons for doing so. Although progress has been made in achieving the goals established in the Clean Water Act (CWA) to restore and maintain the chemical, physical, and biological integrity of the nation's waters, long-standing problems persist, and new problems have emerged. Water quality problems are diverse, ranging from pollution runoff, to toxic substances discharged from factories and sewage treatment plants.
