Groundwater Surface Water Interactions

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...

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.

Concentrations of arsenic in four segments (reaches) of the Wallkill River and one segment of the Papakating Creek (a major tributary to the Wallkill River) have been found to exceed the New Jersey surface-water-quality standard of 0.0170 micrograms per liter. As a result, the U.S. Geological Survey (USGS) New Jersey Water Science Center, in cooperation with the New Jersey Department of...

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.

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. In order to properly manage this resource, there needs to be a consistent dataset of hydrologic data available for...

The Sandy Hook Unit, Gateway National Recreation Area (hereafter Sandy Hook) in New Jersey is a 10-kilometer-long spit visited by thousands of people each year who take advantage of the historical and natural resources and recreational opportunities.

The 2017 Work Plan for the National Resources Protection Program (NRPP) project on Fire Island, Sandy Hook, and Assateague includes a description of the issues and implications; description of the methods; and summary of the 2017 tasks, including site selection, well and instrumentation installation, and monitoring groundwater levels, temperature, and specific conductance.
