Advanced Capabilities and Modeling

The USGS New Jersey Water Science Center provides hydrologic technical assistance to the U.S. Air Force Civil Engineer Center at Joint Base McGuire-Dix-Lakehurst (JBMDL) in New Jersey, regarding contamination issues associated with perfluoroalkyl substances (PFAS), such as perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), in groundwater and surface water.

Frequently, water withdrawals for public supply are made from the freshwater reaches of rivers and streams across new Jersey. Overall, there is a lack of scientific information describing the movement of saltwater upstream into the tributaries discharging into Delaware Bay. This project is beginning to collect water quality data along three selected tributaries in New Jersey to Delaware Bay in an...

On October 29, 2012, Hurricane Sandy made landfall in New Jersey after several days of impacting the Atlantic coastline. Ten years later the impacted communities have recovered and rebuilt, and the New Jersey Water Science Center has expanded its scientific understanding of storm impacts on our state.

As part of the USGS Next Generation Water Observing System the NJWSC is evaluating the use of passive samplers, or Solid Phase Adsorption Toxin Tracking (SPATT) samplers, to examine the temporal variability of dissolved cyanotoxin occurrence. These innovative, low-cost, time-integrated passive samplers offer several advantages over current water-column cyanotoxin monitoring techniques. However...

The purpose of the Program is to develop a sound understanding of the potential for development of potable groundwater supply in selected African countries and build local capacity to plan and conduct the hydrologic investigations and monitoring necessary to help ensure that groundwater resources are developed and managed efficiently and sustainably.

The US Geological Survey collaborated with Northern Arizona University and New Mexico State University in a project funded by the United States Agency for International Development-Kenya and East Africa Mission to investigate the use of satellite image data, along with hydrological and geological data sets, to research and develop maps of potential of groundwater resources in the Athi and Tana...

The US Geological Survey collaborated with Northern Arizona University and New Mexico State University in a project funded by the United States Agency for International Development-Kenya and East Africa Mission to investigate the use of satellite image data, along with hydrological and geological data sets, to research and develop maps of the potential of groundwater resources in southern Turkana...

As part of the Urban Water Federal Partnership, the USGS NJWSC and the Delaware River Basin Commission are currently assessing the use of innovative, near real-time bacteria monitoring technology to provide rapid results on bacteria concentrations to water regulators. Traditional methods of collecting and quantifying fecal indicator bacteria (FIB) is labor intensive, expensive, and may be...

The Current Period Streamflow Statistics project is computing low flow statistics for both a historic (1950-1979) and more recent (1990-2019) 30-year period. The computed statistics will provide information about streamflow changes over time and an evaluation of more recent streamflow conditions. The project will also present land-use changes, precipitation patterns, and water use in the...

The temperature, water quality, and channel connectivity along headwater stream networks often show highly dynamic spatiotemporal patterns that are tied to localized hydrogeologic and landcover controls. Groundwater exchanges exert a spatially discontinuous influence on streams that reflect, in part, the preferential nature of groundwater discharge as controlled by recharge, topography, and...

An online geonarrative consisting of an interactive discussion and maps of the groundwater resources of 10 confined aquifers beneath Central and Southern New Jersey, provides a view of the geology, hydrology and water use in this area. A regional-scale groundwater-level survey of the New Jersey Coastal Plain by the U.S. Geological Survey (USGS) is highlighted. These assessments, performed every 5...

StreamStats is a web application (Web Tool) for water-resources planning and engineering purposes. The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, generate basin characteristics and estimate flow statistics for the selected sites. Users also can select the locations of USGS data-collection stations, shown as triangles on the StreamStats map...
