Abstract:
A Well Head Protection Area (WHPA) is both an area modeled around an unconfined Public Community Water Supply (PCWS) well in New Jersey that delineates the horizontal extent of groundwater captured by a well pumping at a specific rate over two-, five-, and twelve-year periods of time for unconfined wells and a fifty foot radius delineated around each confined PCWS well (This corresponds to the water purveyor controlled wellhead area as defined in the Safe Drinking Water Regulations (see NJAC 7:10-11.7(b)1)). WHPA delineations are created in compliance 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. The WHPAs were previously defined using line and polygon coordinate files and the Arc/INFO Generate command. Individual WHPAs were then combined into county and statewide coverages with the Arc/INFO Union command. The WHPAs are currently created using the same coordinate files using a Python-based feature creation script producing an ArcGIS geodatabase feature. The individual features are then combined using ArcGIS merge command. Previous WHPA coverages were updated to features also and combined into a statewide WHPA feature. The WHPA feature is distributed as either an ArcGIS shapefile or a layerpack file. The 2011 and earlier WHPA delineation methods are described in "Guideline for Delineation of Well Head Protection Areas in New Jersey" available as a download at <http://www.state.nj.us/dep/njgs/whpaguide.pdf>. Due to security consideration, the PCWS well features are not available for direct download but may be requested from the NJDEP.
Purpose:
WHPA delineations are created in compliance to the Safe Drinking Water Act Amendments of 1986 and 1996.
Supplemental_Information:
Note: OBJECTID, shape, shape_length, shape_area are default system variables. TIER is the item that is used for labeling the tiers of the WHPA delineations. TIER 1 is 2 year time of travel, Tier 2 is 5 year time of travel, Tier 3 is 12 year time of travel. WELLID is a unique identifier or each WHPA. Alias if the item used to match each WHPA to the PCWS point feature database. Pre 2009, the ID was the permit #. From 2010 on, the WELLID is a sequential number starting with the year they were created. Note: The data was mapped at a scale of 1:24,000.

Attribute_Accuracy_Report:
Each polygon (tier) was visually checked on screen to quality control the tier values.
Logical_Consistency_Report:
The geodatabase feature was generated based on point coordinates (well locations) of pcws wells which were located using Global Positioning System (GPS) and tested against known benchmarks. The GPS locations are accurate to within plus or minus 40 feet in any direction. The methodology of how the tiers were generated is documented in the "Guidelines for Delineation of Well Head Protection Areas in New Jersey" available as a download at: <http://www.state.nj.us/dep/njgs/whpaguide.pdf>

Process_Description:
The WHPA delineations were; until 2011; exclusively created using the methods outlined in "Guidelines for Delineation of Well Head Protection Areas in New Jersey" available as a download at <http://www.state.nj.us/dep/njgs/whpaguide.pdf>. Coordinate files delineating each WHPA boundary were generated using a custom MS-DOS program on-file at the offices of the N.J. Geological Survey. The resultant coordinate files are formatted as comma delineated ASCII-text and contain line coordinate pairs for each of the groundwater time of travel tiers. Up until 2011, coverages were generated with the Arc/INFO Generate command having both arc (line) and polygon attributes for the three Time of Travel (TOT) tiers. County and statewide WHPA coverages were created using the Arc/INFO Union command. The coverages were then converted to shapefiles. After 2015, the existing individual WHPA coverages were converted to ArcGIS geodatabase features into county feature classed. These features were combined into county-based and then a statwide WHPA feature using the ArcGIS Merge command. New WHPA geodatabase features are generated using an Arc/GIS Python-based, feature-creation script. Each new WHPA is merged into the existing statewide feature. WHPA delineations are considered to have an accuracy of plus or minus 40 feet in any direction from the mapped location. WHPA delineations for wells completed in the glacial sand and gravel aquifer were clipped to a custom hydrologic boundary. Sand and gravel aquifers occur where deposits are more than 50 feet thick. The hydrologic boundary is generated as a 2000 foot buffer around the polygon representing the contact of the sand and gravel aquifer for those areas where the aquifer is less than 50 feet thick. This distance was selected based on an average distance between the 50 and 100 foot thickness contours of the sand and gravel aquifer. The average inter contour distance was doubled to provide a conservative estimate of the thickness variation. Therefore, any portion of the WHPA delineation that lies beyond this extent is clipped. For the confined wells a fifty foot buffer was used to delineate the well head protection area. Note: Since 2009, the permit number naming system has changed in the Bureau of Water Allocation winthin the New Jersey Department of Environmental Protection. Because of this, a new alias number is given as the WELLID for each individual well head protection area delineated and is not directly related to the permit number for the well. A web page with the information for new wells can be found at the following link: <http://www.nj.gov/dep/njgs/geodata/whpafilelist.htm>. After 2015 a new ALIAS field allows each WHP to be joined to its associated PCWS well. Due to security consideration, the PCWS well features are not available for direct download but must be requested from the NJDEP.
