Surface Water Management
When rain falls on land and impervious areas such as paved streets, parking lots, and building rooftops, it can wash away sediments, oil, grease, chemicals, nutrients, metals, litter, and pathogens. Left unmanaged, these pollutants enter our lakes and streams via the surface-water storm drain system, significantly contributing to the degradation of these important resources. Another source of water pollution is the phosphorus from leaves and lawn clippings. These nutrients turn lakes and rivers green with algae.
