Welcome to the Colorado Nonpoint Source Community Website

This site contains information about nonpoint source pollution in Colorado, about what the program and its partners are doing to reduce it and how you can also become a partner. We welcome your feedback.

Unlike pollution from industrial and sewage treatment plants, nonpoint source (NPS) pollution comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters. Nonpoint source pollution is the leading cause of water quality problems.
