New Jersey Department of Environmental Protection, New Jersey Geological SurveyA Well Head Protection Area for a Public Non-Community Water Supply Well (PNCWS) in New Jersey is a map area calculated around a Public Non-Community Water Supply well that delineates the horizontal extent of ground water captured by a well pumping at a specific rate over a two-, five-, and twelve-year period. GIS coverages are produced for each PNCWS well and for the set of all PNCWS wells in each county and for the state. The individual, county and state coverages are prepared for distribution as uncompressed ARC/INFO export files. The export files are combined with parameter-reference files for each county in compressed 'zip' files for delivery over the Internet. Public Non-Community Water Supply Well Head Protection Area downloads therefore include line and polygon GIS coverages with associated database files, and parameter-reference files for data documentation. The documentation files are ASCII text files having the 'txt' extension. WHPA delineation methods are described in "Guidelines for Delineation of Well Head Protection Areas in New Jersey" available as a download at www.nj.gov/dep/njgs/whpaguide.pdf.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/ded763e86c494eb5997a9970b4d4bfea_26engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicWell Head Protection Areas for Public Non-Community Water Supply Wells in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
