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.
Clean Water. Strong Communities.
Water is the foundation for healthy communities and strong economies.

Call if you see things like illegal dumping, spills and overflows, visibly contaminated streams, or connections or discharges into the streets or storm drains.
