Abstract: This GIS data-set represents the source water areas for each active public (community and non-community) surface water intake. The surface water source water areas for all wells considered under the direct influence of surface water (GWUDI) are also included. A surface water source water area represents the surface ground area where water will flow overland past the intake location. The source water areas were delineated from the intake location or a controlling structure, such as a dam or weir, to the headwaters of all tributaries upstream of the intake. For more information on the surface water source water areas refer to https://nj.gov/dep/watersupply/swap. The source water assessment process determined the susceptibility (Low, Medium, or High) of each intake to 8 contaminant groups (Disinfection Byproduct (DBP) Precursors, Inorganics, Nutrients, Pathogens, Pesticides, Radionuclides, Radon, and Volatile Organic Compounds (VOCs)) which can also be linked to for geographical display.
Purpose: The surface water source water areas, in this data-set represent the source water areas for each public community and non-community surface water intake active as of 200301. Surface water source water areas for groundwater under the direct influence of surface water are also included in this data-set. The treatment facilities for these intakes may have a groundwater component (wells) as well, however only the surface water contribution is mapped in this data-set. Surface water source water areas were created as part of the NJ Source Water Assessment Program. They represent the land surface area where water will travel overland past the intake structure. They were delineated from the intake or the intake's controlling structure (dam or weir) to the headwaters of all tributaries upstream of the intake. Intake's located on the Delaware River were delineated using the same process, however a 25 hour time of travel on the main stem of the Delaware was used to break the upstream boundary. Intakes located on the Delaware and Raritan canal included any identified tributaries and a 300 foot zone on each side of the canal for the length of the canal.

Attribute Accuracy Report: The attributes are complete and accurate as of January 2003.
Logical Consistency Report: none
Completeness Report: As of January 2003 all active drinking water intakes source water areas are mapped in this data-set.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: The surface water source water area delineations were generated based on point coordinates (intake locations) located using the Global Positioning System (GPS). These locations have an accuracy of plus or minus 10 meters. Any controlling structures were identified using the 1995 digital orthophotographs (1:12,000 scale). The USGS hydrologic unit code 14 (HUC 14) (1:24,000) polygon coverage was used as the base data-set to delineate the upstream source water area or watershed for each intake location.
Positional Accuracy:
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: No vertical scale was used in the data set.
