The Catskill Watershed Corporation - CWC Stormwater Program
A significant source of water quality impairment is stormwater runoff from impervious surfaces such as paved streets, parking lots and building rooftops during rainfall and snowmelt periods. This runoff carries pollutants such as oil, antifreeze, pesticides, fertilizer, heavy metals and pathogens that can contaminate streams, rivers, lakes and reservoirs.
