Groundwater

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...

The water quality of New Jersey's water bodies is monitored by the USGS New Jersey Water Science Center to characterize waters, identify trends over time, identify emerging problems, determine whether pollution control programs are working, help direct pollution control efforts to where they are most needed, and respond to emergencies such as floods and spills.

The accurate, long-term monitoring networks of New Jersey Water Science Center provide valuable data in real-time and historical perspective to compare that data to. The longer a monitoring location is in operation, the more valuable it becomes, since more statistical comparisons can be performed. Our field technicians continuously make field measurements and maintain these networks.

The Model Maintenance program, in cooperation with the N.J. Department of Environmental Protection (NJDEP), archives, maintains, updates, and shares groundwater-flow models that have been developed by the New Jersey Water Science Center (NJWSC). The program was started in 1995 to maintain existing groundwater flow models, use standardized procedures to archive the models, update models with recent...

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.

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...

The primary source of self-supplied domestic water use is from private wells which are often unmonitored. As a result, estimates of the quantities of water withdrawn are based off of relatively small amounts of data. To gain a better understanding of this type of water use, a project was initiated in cooperation with the New Jersey Department of Environmental Protection to meter private domestic...

Groundwater is the sole source of water supply for many people in New Jersey. Large-scale groundwater pumpage, installation of sanitary- and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and aquifer storage. To properly manage this resource, a consistent dataset of hydrologic data available for water managers and scientist...

The NJWSC conducts research and investigations related to topics such as groundwater and surface-water quality related to anthropogenic and agricultural activities, hydraulic and hydrologic modeling, tracking the movement of groundwater contamination, groundwater resource assessments and modeling, ecological assessments and response to urbanization, and estimating water-use for human and...

Water Resources Data reports were published annually for many decades for use by engineers, scientists, managers, educators, and the general public. These static archival products supplemented direct access to current and historical water data provided by the National Water Information System web interface (NWISWeb), the authoritative source for USGS water data.
