Water Source Areas of New Jersey

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.
