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.<\/SPAN><\/P>

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. <\/SPAN><\/P>
