Aquatic life and other animals feeding from the rivers are destroyed or become seriously ill and eventually die. Recreational swimming, fishing, and boating opportunities become unpleasant or unsafe due to odor, taste and aesthetic problems. Maintenance costs increase because uncontrolled sediment causes erosion and flooding problems. Our drinking water supplies and, therefore, our health is affected by polluted storm water.
