Diagram of how stormwater runs off a city into the storm drainStormwater runoff is one of the leading causes of water pollution in the Chesapeake Bay and around the country. When rain falls on roads, streets, rooftops and sidewalks, it carries harmful pollutants such as fertilizer, pet waste, chemical contaminants and litter into the storm drain. Many residents don’t realize that the stormwater system is not treated. It carries the water, along with all of the pollutants it has picked up, directly to the nearest waterway.
