Data

Hydrologic data collection, processing, analysis, dissemination, and archiving are major parts of the New Jersey Water Science Center program. Streamflow data, for example, are used for flood and water-supply forecasts, planning and design, river regulation, streamflow statistics, and research investigations. Much of the data are available on a near-real-time basis by satellite telemetry.

Stream cross-section, benthic macroinvertebrate and fish taxa counts and abundance, and water chemistry data for the Clarksburg study area in Montgomery County, Maryland, 1992 - 2020

Montgomery County, Maryland Department of Environmental Protection has collected datasets to assess the health of streams since the early 1990s. Datasets include geomorphic stream cross-sectional surveys, fish and benthic macroinvertebrate counts and taxa abundance, and water chemistry data collected at the time of benthic and fish sampling (dissolved oxygen, pH, specific conductance, air temperat

Quality assessed and modified Discharge Monitoring Report (DMR) facility and outfall locations, 2007 - 2019

Each year the U.S. Environmental Protection Agency (EPA) reports permit, location, and discharge information for facilities across the United States and its territories through the Discharge Monitoring Report (DMR). Because these data are cataloged through a variety of systems, including self-reporting, there are discrepancies that may lead to incorrect spatial interpretation of content in the dat

SEAWAT, MODFLOW-2000, and SHARP models used to simulate potential water-allocation changes, Cape May County, New Jersey

Three existing groundwater flow models, using MODFLOW-2000, SEAWAT, and SHARP model codes, were used by the U.S. Geological Survey (USGS) to determine the effects of increased withdrawals, and shifts of withdrawals between 2 aquifers, on the limited water resources in the Cape May County, New Jersey. Saltwater intrusion and declining water levels have been a water-supply problem in Cape May County

Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2020

Estimates of various low-flow statistics were computed at 32 ungaged stream locations throughout New Jersey during the 2020 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 at partial-

MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey

The U. S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, developed a numerical groundwater flow model, using MODFLOW2000, to simulate groundwater flow in the Pohatcong Valley including the area within the Pohatcong Valley Ground Water Contamination Site. In 1978, the chlorinated solvents trichloroethene (TCE) and tetrachloroethene (PCE) were detected in the Pohatc

SEAWAT, MODFLOW-2000, and SHARP models used to simulate future water-supply scenarios, Cape May County, New Jersey

Three groundwater flow models, using MODFLOW-2000, SEAWAT, and SHARP model codes, were used to evaluate plans to supply potable and non-potable water to residents and businesses of Cape May County, New Jersey until at least 2050. The ideal plan would meet projected demands and minimize adverse effects on currently used sources of potable, non-potable, and ecological water supplies. The U.S. Geolog

MODFLOW-2005 model used to simulate water-table response to climate-change-driven sea-level rise and changes in recharge, Gateway National Recreation Area, Sandy Hook Unit, New Jersey

A MODFLOW-2005 model, using the SWI2 package, was developed for the Sandy Hook Unit, Gateway National Recreation Area (hereafter Sandy Hook) in New Jersey to evaluate the response of groundwater resources to expected sea-level rise (SLR) and changes in groundwater recharge associated with global climate change. The National Park Service (NPS), among other agencies, is mandated to evaluate the effe

High-water marks in New Jersey following Hurricane Ida and associated floods, September 2021

The data contained within include high-water marks collected at 50 sites throughout the regions of New Jersey affected by significant flooding from Hurricane Ida during September of 2021. Each site contains between one to six associated high-water marks that were documented, photographed, and surveyed to datum. The datum represented by the elevations of the high-water marks is the North American V

Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed, 1950-2050

Reactive nitrogen is transported from the atmosphere to the landscape as wet and dry deposition that contributes to annual nitrogen loads to the Chesapeake Bay. Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed during 1950 to 2050 are presented, and are based on field measurements, model simulations, statistical relations, and surrogate constituents used for es

Public supply, self-supplied domestic, irrigation, and thermoelectric water-use data from 5-year compilation datasets from 1985 to 2015 used to assess data variability and uncertainty

The U.S. Geological Survey (USGS) National Water Use Program is responsible for compiling and disseminating the Nation's water-use data. Working in cooperation with local, State, and Federal agencies, the USGS has published an estimate of water use in the United States every 5 years, beginning in 1950. These 5-year compilations contain water-use estimates that are aggregated to the county level in

Current use pesticides in larval amphibian tissues, amphibian pathogen and wetland sediment screening data from three northeastern National Wildlife Refuges, 2013-2014

The data include concentrations of current use pesticides in tissues of larval wood frog (Lithobates sylvaticus) and spotted salamander (Ambystoma maculatum) and the presence of ranavirus in wood frogs and spotted salamanders from three northeastern National Wildlife Refuges sampled in 2013 and 2014. The data also include estrogenicity, protein phosphatase 2A inhibition and a suite of 15 major and

Concentrations of chlorinated volatile organic compounds and per- and polyfluoroalkyl substances in groundwater and surface water, former Naval Air Warfare Center, West Trenton, New Jersey

This dataset contains a compilation of concentrations of chlorinated volatile organic compounds (VOCs) and per- and polyfluoroalkyl substances (PFAS) in groundwater and surface water sampled at the former Naval Air Warfare Center, West Trenton, New Jersey. Measured VOCs include trichloroethene (TCE), cis- 1,2-dichloroethene (cisDCE), and vinyl chloride (VC). Semi-volatile organic compound 1,4-diox
