Every time it rains, water runs off the land as stormwater. As it flows over rooftops, lawns, driveways and streets, stormwater picks up pollutants and debris.
EPA’s National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States.
Everyone should report spills, clogged catch basins or retention ponds, illegal dumping, and illicit connections or discharges into the streets or storm drain system.
Use our online Pollution Reporting Form or contact us to make a report on any of the following: waste hot spots, spills, clogged catch basins, illegal dumping, and illicit connections or discharges into the streets or storm drain system.
