Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This GIS map service provides the locations of Transient Non-Community (TNC) drinking water systems across Maryland. The TNCs are defined by the Environmental Protection Agency (EPA) as drinking water systems that are not a community water system across an area, but contained on the property where they are located, primarily for a specific building/facility. The TNC regularly serve 25 or more people each day, but not the same people every day. This type of system can be found at gas stations, churches, restaurants, campgrounds, and other like facilities where people do not remain for long periods of time.</SPAN></P><P><SPAN>Note - The spatial locations of the TNC water systems were derived from the street address for that site and do not represent the actual location of the water system's infrastructure. </SPAN></P><P><SPAN>The data fields within this GIS data layer are as follows:</SPAN></P><P><SPAN>Public Water system Identification (PWSID):</SPAN></P><P STYLE="text-indent:20;"><SPAN>The PWSID is a unique number used to identify water systems within a specific state.</SPAN></P><P><SPAN>System Name:</SPAN></P><P STYLE="text-indent:20;"><SPAN>This is the name of the water system.</SPAN></P><P><SPAN>Water Source Description:</SPAN></P><P STYLE="text-indent:20;"><SPAN>This column identifies the primary source of the water used by the water system:</SPAN></P><UL><LI><P><SPAN>GW: Groundwater.</SPAN></P></LI><LI><P><SPAN>GWP: Groundwater purchased.</SPAN></P></LI><LI><P><SPAN>SW: Surface water.</SPAN></P></LI><LI><P><SPAN>SWP: Surface water purchased.</SPAN></P></LI><LI><P><SPAN>GU: Groundwater under influence of surface water.</SPAN></P></LI><LI><P><SPAN>GUP: Purchased groundwater under influence of surface water source.</SPAN></P></LI></UL><P><SPAN>County:</SPAN></P><P STYLE="text-indent:20;"><SPAN>Name of the county in which the water system is located.</SPAN></P><P><SPAN>Data Source:</SPAN></P><P STYLE="text-indent:20;"><SPAN>This field lists the origin of the displayed water system locations and data:</SPAN></P><UL><LI><P><SPAN>MDE: Internal files.</SPAN></P></LI><LI><P><SPAN>Water System: File provided by system.</SPAN></P></LI><LI><P><SPAN>County GIS: County provided GIS layers.</SPAN></P></LI><LI><P><SPAN>County W&amp;S: Water &amp; Sewer Plan Maps.</SPAN></P></LI><LI><P><SPAN>SDWIS: Information from State database.</SPAN></P></LI></UL></DIV></DIV></DIV>
