Abstract: NJ Highlands Region Well Head Protection Area.
Purpose:
Well Head Protection Area 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 NJ Highlands Council uses these areas to inform the planning process and Regional Master Plan implementation.
Supplemental_Information:
Well Head Protection Areas in New Jersey is a map area calculated around a 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 well and for the set of all 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. 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.state.nj.us/dep/njgs/whpaguide.pdf.
A Public Non-Community Water Supply Well is a public water supply well used by individuals other than year-round residents for at least sixty days of the year. A non-community water supply well can be either transient or nontransient. A nontransient non-community water supply well serves at least twenty-five of the same people over a period of six months during the year, such as schools, factories, and office buildings. A transient non-community water supply well is a well that serves year around for at least sixty days of the year, but does not serve the same individuals during that time period. Transient non-community water supply wells include rest stop areas, restaurants, and motels.
Note: This metadata references the Public Non-Community Water Supply Well Head Protection Areas (njncwhpa) coverage for the entire state.
Note: These coverages were mapped at a scale of 1:24,000.
Note: For a listing of Public Non-Community Water Supply delineations in New Jersey see the link on the downloads page.
The NJ Highlands Council clipped the State's Well Head Protction Area to the NJ Highlands Region.

Attribute_Accuracy_Report:
Each polygon (tier) was visually checked on printed maps to quality control the tier values.
Logical_Consistency_Report:
These coverages were generated based on point coordinates (well locations) of PNCWS wells which were located using the Global Positioning System (GPS) and tested against known benchmarks. The GPS locations have an accuracy of plus or minus 40 feet in any direction from the mapped location.

Process_Description:
The WHPA delineations for public non-community water supply wells were generated from a Microsoft Access database created with data from the NJDEP Bureau of Safe Drinking Water and the New Jersey Geological Survey. The database was constructed with all of the available well construction information, depths and pumping rates available for the wells. A statistical analysis was done for each county by NJGS to determine the median values for the depth and pumping rate. These values were assigned to those wells for which the depth and pumping rate were unknown. In addition, the porosity was determined by overlaying the Microsoft Access database of well points after being converted into an ESRI point shapefile onto a surficial geologic map. Those wells in rock aquifers were assigned a value of 0.02 for the porosity and those in unconsolidated aquifer were assigned a value of 0.25. The CFR's for 2, 5 and 12 years were then calculated using the equations:
((pumping rate * time) / (porosity * 3.1415 * depth))^0.5
(([Q]*192.5*730)/([porosity]*3.1415*[depth]))^0.5 2 year CFR
(([Q]*192.5*1825)/([porosity]*3.1415*[depth]))^0.5 5 year CFR
(([Q]*192.5*4380)/([porosity]*3.1415*[depth]))^0.5 12 year CFR
An ASCII text file was then created from this database. The text file consisted of the Bureau of Safe Drinking Water ID number, location, tier 1 cfr, tier 2 cfr and tier 3 cfr. This file was processed using a BASIC program (Noncom.exe) which created the file format needed for importing the data into ARC/INFO. In ARC/INFO the GENERATE command was used to create the delineations. The noncom.exe program was developed by NJGS for creating the PNCWS delineations.
Each WHPA coverage was built as both a line and a polyon coverage having both arc and polygon attributes for the three Time of Travel (TOT) tiers. The public non-community water supply well head protection areas state coverage (njcnwhpa) and the 20 county coverages were processed using the UNION command in ARC/INFO to create the state and county coverages from the individual coverages.
The available construction and pumping information used to create these WHPA delineations are available in the associated PNCWS point shapefile available by request from the State Geologist, N. J. Geological Survey, Box 427, Trenton, NJ 08625
The final State dataset was clipped on the Highlands Region.
