Stephen J Cauller
His current investigation involves measurement and mapping of the potentiometric surface in 10 confined aquifers of the NJ Coastal Plain, with results being tailored for delivery via a web-map interface. Stephen is also the GIS Specialist in the NJ Water Science Center where he assists coworkers with the use of geographical information systems software.
Employment as a hydrologist with the USGS has afforded him the opportunity to work on a variety of hydrologic studies, including a Toxic Substances investigation on Long Island, NY that related shallow groundwater quality to land use. He spent several years working on the database design and application development team of the Nation Water Information System (NWIS). Over the past 20 years, he has directed numerous groundwater studies in the coastal plain of New Jersey. His work has involved groundwater levels and mapping, chloride concentrations in groundwater, hydrogeologic framework analysis, water quality summaries, multiple aquifer 3D groundwater flow model development and particle tracking, and the advective transport of nitrogen in groundwater. Recent work includes flood innundation studies in West Virginia and Maine and stream network derivation studies employing various methodologies including StreamStats, ArcHydro Tools and a tophat method using lidar-derived DEMS.

Groundwater Resources of the New Jersey Coastal Plain
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...Water Levels in the Ten Major Confined Aquifers of the New Jersey Coastal Plain
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...New Jersey Groundwater Network
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...Surficial Aquifer Studies
The series of surficial aquifer studies were completed to evaluate the unconfined aquifer system of the NJ Coastal Plain for use as a potential source of water. As the demand for water in the State increases and the restrictions continue on the use of water from certain confined aquifers, withdrawals on the unconfined aquifer system are expected to increase. Detailed study of the unconfined... - Data
