A three-dimensional groundwater flow model was developed to simulate the effects of withdrawals on the groundwater-flow systems of five aquifers in and around Ocean County, New Jersey—the unconfined Kirkwood-Cohansey aquifer system and Vincentown aquifer, and three confined aquifers--the Rio Grande water-bearing zone, the Atlantic City 800-foot sand, and the Piney Point aquifer. A transient model was used to simulate conditions that represent no groundwater withdrawals, 2000–2003 groundwater withdrawals, and maximum-allocation groundwater withdrawals. Particle-tracking analysis, using results from two steady-state simulations, determine flow paths and travel times to near-shore wells screened in the unconfined Kirkwood-Cohansey...
Digital flood-inundation maps for an approximately 295-mile length of the New Jersey coastline and tidewaters through 10-coastal counties stretching from Cumberland County through Bergen County; including Cumberland, Cape May, Atlantic, Ocean, Monmouth, Middlesex, Union, Essex, Hudson, and Bergen counties were created by the U.S Geological Survey (USGS) in cooperation with the New Jersey Department of Environmental Protection (NJDEP) and New Jersey Office of Emergency Management (NJOEM). The flood-inundation maps depict extent and depth estimates of coastal flooding corresponding to selected tidal elevations recorded by 25 real-time USGS tide gages located throughout the length of the study area coastline. The flood-inundation...

A three-dimensional groundwater flow model using MODFLOW 6 (version 6.2.2) was developed and calibrated for unconsolidated Coastal Plain aquifers underlying the Joint Base McGuire-Dix-Lakehurst (JBMDL) and vicinity, New Jersey, to evaluate groundwater flow pathways of per- and polyfluoroalkyl substances (PFAS) contamination associated with use of aqueous film forming foam (AFFF). The model was developed and calibrated by the U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force Civil Engineer Center (AFCEC) based on the previously developed hydrogeologic framework (https://doi.org/10.3133/ofr20191134). Steady-state flow in the unconsolidated aquifers was simulated using the MODFLOW 6 which accounts...
A third revision of the New Jersey Coastal Plain (NJCP) groundwater flow model, using MODFLOW-2005 (version 1.12.00), was completed to maintain the model’s usefulness for water-resource managment and development. The regional groundwater-flow model was initially developed for the U.S. Geological Survey (USGS) Regional Aquifer System Analysis (RASA) program. Periodic revision of the model is required as the result of changing hydrologic stresses, different and more complex water management needs, and increased knowledge of hydrologic conditions. The RASA model was initially constructed in the 1980’s as a quasi-3D model with 10 aquifers. The 9 intervening confining units were simulated using vertical leakage parameters...
A groundwater-flow model that was previously developed by the U. S. Geological Survey of Ocean County, N.J. (https://doi.org/10.3133/sir20165035) was used in an analysis of groundwater flow in the Kirkwood-Cohansey aquifer system and deeper confined aquifers that underlie the Barnegat Bay-Little Egg Harbor (BB-LEH) watershed and estuary. The analysis used a MODFLOW2005 simulation, in conjunction with the particle-tracking computer program MODPATH (Pollock, 1994), to delineate particle flow paths, the discharge location of each particle, and estimate the travel time along flow paths to the BB LEH estuary and streams within the BB-LEH watershed. This study conducted by the USGS, in cooperation with the Barnegat Bay...
This dataset contains 10 raw common-offset ground-penetrating radar (GPR) profiles collected at 7 locations in the Edwin B. Forsythe National Wildlife Refuge, Atlantic County and Ocean County, New Jersey, in October and November 2014 and January 2015. A MALA® 80 megahertz (MHz) HDR shielded antenna was used for 3 profiles named DinnerPointAve, GameFarmRd-1, and GameFarmRd-2. A MALA® 100 MHz shielded antenna was used for 7 profiles named ReedyCreek-1, ReedyCreek-2, ScottsLandingRd, SouthWildlifeDr, StaffordAve-eastwest, StaffordAve-westeast, and WescottAve. Pre- and post-processing methods such as filters, topographic corrections, wave velocity determinations, and depth conversions have not been applied to these...
A three-dimensional groundwater-flow model (MODFLOW-2000 ) of the Kirkwood-Cohansey aquifer system, Rio Grande water-bearing zone, and Atlantic City 800-foot sand in the Great Egg Harbor and Mullica River Basins, N.J. was developed to simulate the effects of withdrawals on streamflow and groundwater supply. Increasing groundwater withdrawals from the unconfined Kirkwood Cohansey aquifer system is a major concern because of the potential for streamflow depletion and the resulting ecological effects on aquatic habitats, wetlands, and vernal ponds. In the confined Atlantic City 800-foot sand aquifer water levels have been steadily declining and most of the groundwater withdrawn from the Atlantic City 800-foot sand...
