Groundwater Discharge Points

The Department of Environmental Protection (DEP) Division of Watershed Management (DWM) Water Permitting Program (WPP) is responsible for regulating the discharge of pollutants to the ground waters of The Commonwealth (314 CMR 5.00). See http://www.mass.gov/dep/water/resources/groundwa.htm for details. The Ground Water Discharge Permits datalayer (formerly known as Groundwater Discharge Points) is a statewide point dataset containing approximate locations of permitted discharges to groundwater. The permitted discharges in this datalayer may have one or more of the following criteria: Sanitary sewage in excess of 10,000 gallons per day (gpd) Discharges of non-contact cooling water Discharges from coin operated laundromats Discharges from carwashes Discharges from treatment systems designed to remediate contaminated groundwater
