The Maryland Department of Transportation State Highway Administration (MDOT SHA) uses source control best management practices (BMPs) to remove trash, sediments and other debris on roadway surfaces that contain pollutants before they are washed into adjacent waterways.
Mechanically sweeping the roadway removes trash, leaves, dirt, sand and other debris from curbs, gutters, and bridge parapets. The material is then properly removed to approved landfills. Street sweeping provides two benefits: first, it prevents buildup along roadways, allowing water to flow freely from highways into the drainage system. Second, it removes pollutants from passing vehicles or pollutants washed onto the roadway before they can reach local waterways.
