DGS04-5 Well Head Protection Areas For Public Non-Community Water Supply Wells In New Jersey.



A Well Head Protection Area for a Public-Non Community Water Supply Well (WHPA) in New Jersey is a map area calculated around a Public Non-Community Water Supply Well (PNCWS) 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.  PNCWS coverages 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 delineations are conducted in response to the Safe Drinking Water Act Amendments of 1986 and 1996 as part of the Source Water Area Protection Program (SWAP). The delineations are the first step in defining the sources of water to a public supply well.  Within these areas, potential contamination will be assessed and appropriate monitoring will be undertaken as subsequent phases of the NJDEP SWAP.  WHPA delineation methods are described in "Guidelines for Delineation of Well Head Protection Areas in New Jersey" available as a download at ( ) .
