Geospatial data representing wells open to, and 2018 potentiometric-surface contours of, the confined aquifers of the New Jersey Coastal Plain

This dataset contains the well-location information and water-level measurements for 930 wells from 10 confined aquifers of the New Jersey Coastal Plain. Well-location and water-level data is publicly available from the U.S. Geological Survey (USGS) Water Data for the Nation database (USGS, 2025). Water-level measurements from 3 wells in Pennsylvania and reported water-level measurements from 18 wells in Delaware (Delaware Geological Survey [variously dated]) also are included. All measurements were collected from mid-October 2018 to early April 2019 and used to construct potentiometric-surface maps for the confined Cohansey aquifer, Rio Grande water-bearing zone, Atlantic City 800-foot sand, Piney Point aquifer, Vincentown aquifer, Wenonah-Mount Laurel aquifer, Englishtown aquifer system, and upper, middle, and lower aquifers of the Potomac-Raritan-Magothy (PRM) aquifer system. This dataset also contains shapefiles of the potentiometric surface contours for the 10 confined aquifers. The potentiometric-surface contours show altitudes at which water levels would have risen in tightly-cased wells and represent conditions in October 2018 through early April 2019.
