Water Levels in the Ten Major Confined Aquifers of the New Jersey Coastal Plain
The Coastal Plain aquifers of New Jersey provide an important source of water for more than 3.5 million people. The USGS, in cooperation with the New Jersey Department of Environmental Protection, has been measuring water levels in the confined aquifers of the New Jersey Coastal Plain every five years beginning in 1978. Persistent, regionally extensive cones of depression are present in Ocean and...
Coastal Plain Aquifer Synoptic - Chloride Network
Chloride concentrations in groundwater are measured in select wells on a 5-year cycle, as an early warning indicator of saltwater intrusion, and for the definition of the 250 mg/L chloride concentration line within the principal aquifers of the New Jersey Coastal Plain.
Water Quality Analysis Simulation Program (WASP) eutrophication model for the Barnegat Bay-Little Egg Harbor Estuary, New Jersey, USA. Water Quality Analysis Simulation Program (WASP) eutrophication model for the Barnegat Bay-Little Egg Harbor Estuary, New Jersey, USA.
The U.S. Geological Survey (USGS) developed and calibrated a Water Quality Analysis Simulation Program (WASP) model (version 8.4) for the Barnegat Bay-Little Egg Harbor Estuary (hereafter referred to as 'the Estuary'), New Jersey. This model was externally coupled with a previously developed hydrodynamic model (Defne and Ganju, 2015 and 2018) to simulate dissolved oxygen, nutrient...
Geochemical and mineralogic investigation of elevated arsenic and trace element concentrations in glauconitic soils and sediments of the New Jersey Inner Coastal Plain Geochemical and mineralogic investigation of elevated arsenic and trace element concentrations in glauconitic soils and sediments of the New Jersey Inner Coastal Plain
The U.S. Geological Survey New Jersey Water Science Center (USGS NJWSC) in cooperation with the New Jersey Department of Environmental Protection (NJDEP) has assembled this data release in support of ongoing USGS and NJDEP evaluations related to the occurrence and distribution of elevated trace elements, particularly arsenic (As) and vanadium (V), in Inner Coastal Plain soils and...
WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey
A one-dimensional surface-water quality model of the central Salem River Basin, New Jersey was developed to examine the causes of eutrophication and predict the effects of reduced point and nonpoint source nutrient loads on water quality. The model was developed using the USEPA WASP code. The model simulates channel flow and the fate and transport of dissolved oxygen, oxygen demands...
Benthic pore water and sediment data Barnegat Bay, New Jersey, 2012-2013 Benthic pore water and sediment data Barnegat Bay, New Jersey, 2012-2013
This data set presents pore water nutrient concentrations and sediment oxygen demand (SOD) measurements made at 12 locations around the margin of Barnegat Bay and at 3 locations in central Barnegat Bay. The data were collected during 2012-2013 for the Barnegat Bay Nutrient Study in cooperation with the New Jersey Department of Environmental Protection. Table 1 presents the site data...

Use of multi-resolution, three-dimensional hydrodynamic and water-quality models to assess response to nutrient load reductions in Barnegat Bay-Little Egg Harbor estuary, New Jersey, USA Use of multi-resolution, three-dimensional hydrodynamic and water-quality models to assess response to nutrient load reductions in Barnegat Bay-Little Egg Harbor estuary, New Jersey, USA
A coupled three-dimensional hydrodynamic water-quality model has been applied to Barnegat Bay-Little Egg Harbor Estuary, a shallow, back-barrier lagoon located along the central New Jersey coastline. The study aims to enhance understanding of phytoplankton dynamics and nutrient cycling and to quantify estuarine response to potential nutrient load management strategies. The model was...

Predictive understanding of stream salinization in a developed watershed using machine learning Predictive understanding of stream salinization in a developed watershed using machine learning
Stream salinization is a global issue, yet few models can provide reliable salinity estimates for unmonitored locations at the time scales required for ecological exposure assessments. Machine learning approaches are presented that use spatially limited high-frequency monitoring and spatially distributed discrete samples to estimate the daily stream-specific conductance across a...

Simulation of flow and eutrophication in the central Salem River, New Jersey Simulation of flow and eutrophication in the central Salem River, New Jersey
The central Salem River in New Jersey is subject to periods of water-quality impairment, marked by elevated concentrations of phosphorus and chlorophyll-a, and low concentrations of and large diurnal swings in concentrations of dissolved oxygen. These seasonal eutrophic conditions are controlling factors for water quality in lower reaches, where the river is more lacustrine than in upper...

In situ benthic nutrient flux and sediment oxygen demand in Barnegat Bay, New Jersey In situ benthic nutrient flux and sediment oxygen demand in Barnegat Bay, New Jersey
The U.S. Geological Survey, in cooperation with the New Jersey Department of Environmental Protection, measured sediment oxygen demand (SOD) and benthic nutrient fluxes throughout Barnegat Bay, New Jersey. SOD was determined in situ using chambers equipped with optical dissolved oxygen sensors. The benthic nutrient fluxes of ammonia (NH3), nitrite + nitrate (plus ions; here, referred to...

Towards a comprehensive water quality modeling of Barnegat Bay: Development of ROMS to WASP Coupler Towards a comprehensive water quality modeling of Barnegat Bay: Development of ROMS to WASP Coupler
The Regional Ocean Modeling System (ROMS) has been coupled with the Water Quality Analysis Simulation Program (WASP) to be used in a comprehensive analysis of water quality in Barnegat Bay, New Jersey. The coupler can spatially aggregate hydrodynamic information in ROMS cells into larger WASP segments. It can also be used to resample ROMS output at a finer temporal scale to meet WASP...

Water-level conditions in the confined aquifers of the New Jersey Coastal Plain, 2008 Water-level conditions in the confined aquifers of the New Jersey Coastal Plain, 2008
Groundwater-level altitudes in 10 confined aquifers of the New Jersey Coastal Plain were measured and evaluated to provide an overview of regional groundwater conditions during fall 2008. Water levels were measured in more than 900 wells in New Jersey, eastern Pennsylvania, and northern Delaware and potentiometric surface maps prepared for the confined Cohansey aquifer of Cape May County...
