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...

This data release presents cyanotoxin and multiparameter water-quality sonde data collected from July-October 2020, at eleven sites in the Salem River, New Jersey. Data-collection sites included seven flowing and four impounded reaches of the main stem Salem River. Solid Phase Adsorption Toxin Tracking (SPATT) samplers were deployed at 11 sampling locations during the study period and...

This data release contains the concentration and quality-assurance results for inorganic constituents, organic compounds (volatile organic compounds [VOC], per- and polyfluoroalkyl substances [PFAS], pesticides, and disinfection byproducts [DBP]) collected in tapwater from locations in Alabama and Mississippi. Tapwater samples (11 public supply and 1 private well) were collected on...

This data release provides concentration results for per- and polyfluoroalkyl substances (PFAS) collected by volunteer community members, in tapwater samples from 83 private residences, in select areas within the United States. Samples were collected July 1, 2023, through November 10, 2023. Samples were analyzed at the U.S. Geological Survey National Water Quality Laboratory (NWQL) in...

This U.S. Geological Survey (USGS) data release contains a geodatabase, shapefiles, and datasets that describe streamflow characteristics and trends in New Jersey surface water during water years 1903-2017. High-flow, low-flow, and durations statistics and trend results at 97 continuous-record gages are presented. Low-flow statistics at 719 partial-record gages with sufficient data for...

Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2023 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications...

Three withdrawal scenarios spanning from 2014 through 2040 were simulated using a previously published three-dimensional groundwater flow model of the New Jersey Coastal Plain (NJCP) (Gordon and Carleton, 2023). This model, run in MODFLOW-2005 (version 1.12.00), was recently updated by the U.S. Geological Survey (USGS) ensuring the models continued relevance for water-resource management...

This data release contains the concentration results for basic water-quality constituent class parameters (water temperature, pH, turbidity, and specific conductance), total nitrogen, total phosphorous, chloride, and trace elements in surface-water samples collected from two subsites within two vernal pools near Pleasant Grove, New Jersey in 2022-23. In the winter (December 2022 and...

This dataset reports total arsenic (AsTot) results analyzed using an in-field biosensor system, Field-Ready Electrochemical Detector for Arsenic (FRED-Arsenic), developed by FREDsense Technologies Corp., Calgary, Alberta, Canada. Samples were collected from two public-supply wells (NH-SGW 93 and NH-SGW 65) and one private well (NH-KFW 87). NH-SGW 93 and NH-KFW 87 both withdraw water from...

In support of a preliminary analysis performed by New York State Department of Environmental Conservation (NYSDEC) that found elevated nutrient levels along selected reaches of the Mohawk River, one-dimensional, unsteady, hydraulic and water-quality models using HEC-RAS and HEC-RAS Nutrient Simulation Module I (version 5.0.3) were developed by the U.S. Geological Survey (USGS) for the...

This data release provides the concentration results for per- and polyfluoroalkyl substances (PFAS) collected on French Island, in the town of Campbell, Wisconsin, sampled quarterly beginning in 2021. These samples were collected from groundwater wells (potable and non-potable taps) by the U.S. Geological Survey (USGS) Upper Midwest Environmental Science Center (UMESC). Three U.S...

Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2022 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications...
