Description:
Abstract:
This layer is a derivative work of the New Jersey Geological Survey's Well Head Protection layer. The state-wide layer has been modified by the Highlands Council to include only those areas within its borders. In addition, where Well Head Protection Areas overlap the Highlands Council has defaulted to the tier with the shortest travel time.
A Well Head Protection Area (WHPA) is an area calculated around a 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. The confined wells have a fifty foot radius delineated around each well serving as the well head protection area to be controlled by the water purveyor in accordance with Safe Drinking Water Regulations (see NJAC 7:10-11.7(b)1).  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. The area of capture is defined using line boundaries and polygon areas generated with the ARC/INFO Geographic Information System (GIS). A NJWHPA GIS coverage was produced by using the ARC/INFO UNION command on all individual delineations. The statewide NJWHPA file is prepared for distribution as an ESRI shapefile with metadata and ArcView Legend file, njwhpa.avl. 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> An ESRI point shapefile of associated PCWS wells is available as N.J. Geological Survey Digital Geodata Series DGS97-1 (<http://www.state.nj.us/dep/njgs/geodata/dgs97-1.htm>).
Purpose:
WHPA delineation was conducted in response to the Safe Drinking Water Act Amendments of 1986 and 1996.
Supplemental_Information:
This layer is a derivative work of the New Jersey Geological Survey's Well Head Protection layer. The state-wide layer has been modified by the Highlands Council to include only those areas within its borders. In addition, where Well Head Protection Areas overlap the Highlands Council has defaulted to the tier with the shortest travel time.
Note: Area, Perimeter, njwhpa# and njwhpa-ID are default system variables. TIER is the item that is used for labeling the tiers of the WHPA delineations. TRAVELTIME is the item used to label the time it takes water to reach the well.
Note: The data was mapped at a scale of 1:24,000.
Note: This metadata references the UNIONED public community water supply well head protection areas shapefile for the entire state. The individual coverages descriptive information is contained in a .txt file contained in each county download.
For a complete list of all the individual delineations for the public community water supply well head protection areas see the list link on the downloads page.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Each polygon (tier) was visually checked on screen to quality control the tier values.
Logical_Consistency_Report:
The shapefile 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>
Completeness_Report:
The original NJWHPA coverage from which this shapefile was processed contained some "0" tier records as a remnant of the UNION process. In making this shapefile these 0 tiers were removed for data viewing purposes.

Process_Description:
This layer is a derivative work of the New Jersey Geological Survey's Well Head Protection layer. The state-wide layer has been modified by the Highlands Council to include only those areas within its borders. In addition, where Well Head Protection Areas overlap the Highlands Council has defaulted to the tier with the shortest travel time.
The WHPA delineations were 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 MS-DOS coordinate files are formatted as ARC/INFO coverages and contain line attributes specifying each time of travel tier for groundwater to the well. Each coverage was built as both a line and a polygon coverage having both arc and polygon attributes for the three Time of Travel (TOT) tiers. The coverage was then converted to a shapefile. PCWS wells were located using a Global Positioning System (GPS). An Arcview point shapefile of associated PCWS wells is available as N.J. Geological Survey Digital Geodata Series DGS97-1 (<http://www.state.nj.us/dep/njgs/geodata/dgs97-1.htm>).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 welll 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>.
