Name: Non-Transient Non-Community Water Systems

Display Field: PWSID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This GIS map service provides the locations of Non-Transient Non-Community (NTNC) drinking water systems across Maryland. The NTNCs are defined by the Environmental Protection Agency (EPA) as drinking water systems that are not a community drinking water system across an area, but contained within the property where they are located, primarily for a specific building/facility. A NTNC regularly serves at least 25 of the same people over six months of a year. This type of system can be found at schools, daycare centers, manufacturers, hospitals or nursing homes, office buildings, and other facilities.Note - The spatial locations of the NTNC water systems were derived from the street address for that site and do not represent the actual location of the water system's infrastructure. The data fields found within this GIS layer are as follows:Public Water system Identification (PWSID):The PWSID is a unique number used to identify water systems within a specific state.System Name:This is the name of the water system.Water Source Description:This column identifies the primary source of the water used by the water system:GW: Groundwater.GWP: Groundwater purchased.SW: Surface water.SWP: Surface water purchased.GU: Groundwater under influence of surface water.GUP: Purchased groundwater under influence of surface water source.County:Name of the county in which the water system is located.Data Source:This field lists the origin of the displayed water system locations and data:MDE: Internal files.Water System: File provided by system.County GIS: County provided GIS layers.County W&S: Water & Sewer Plan Maps.SDWIS: Information from State database.
