Over the past 25 years, the United States has made tremendous advances to clean up our nation's waterways by controlling pollution from industrial and sewage treatment plants. However, little has been done to address the effects of storm water runoff pollution. Storm water runoff pollution is a leading cause of water quality problems. Nonpoint Source Pollution (NPS) is the primary reason many of our waters are still considered unfit for swimming and fishing. NPS pollution is caused by the everyday impacts of individuals interacting with the land. Each of us can contribute to this problem without even realizing it. Storm water runoff pollution, unlike pollution from industry and sewage treatment plants, can come from a number of sources. This type of pollution is caused by rainfall and snowmelt moving across and through the ground picking up pollutants along the way and depositing them into lakes, rivers, wetlands, and our underground source of drinking water. Fortunately, there are many ways in which we can all help to lower the amount of pollutants reaching our waterways and ground water.
