Martha K Watt
Martha K. Watt is a hydrologist working with the New Jersey Water Science Center Integrated Hydrology Investigation Team and is currently funded by the WMA Integrated Modeling and Prediction Division, Model Support Branch, to assist groundwater modelers with navigation of the Open Data Policy and WMA archiving policy to release their model archives to the public.
From 2003-2016 she was the project chief of the NJWSC Model Maintenance Program which archives, maintains, updates, and shares groundwater flow models completed in the NJWSC. This ongoing program was started in 1995 and since that time 25 New Jersey models have been checked, validated, and archived. The models are posted to the NJWSC webpage where they are available to the public. Martha has and continues, to standardize the checking and archiving process and to support the groundwater projects within the NJWSC. Her work on a variety of groundwater modeling studies has provided the experience needed to assist groundwater modelers with the public release of their model archives.

Two 2-Dimensional models patterned after the Barends analytical solution for verifying the accuracy of the new Groundwater Energy (GWE) Transport model built for the MODFLOW 6 hydrologic simulator
This data release contains two MODFLOW 6 simulations. Each simulation contains one groundwater flow (GWF) model and one groundwater energy (heat) (GWE) transport model. The GWF and GWE models are constructed to match the setup of the Barends analytical solution for two-dimensional heat transport. This allows the accuracy of the new GWE model to be verified so existing and prospective...
MODFLOW-2005 model used to simulate the regional groundwater flow system in the updated New Jersey Coastal Plain model, 1980-2013
A third revision of the New Jersey Coastal Plain (NJCP) groundwater flow model, using MODFLOW-2005 (version 1.12.00), was completed to maintain the model’s usefulness for water-resource managment and development. The regional groundwater-flow model was initially developed for the U.S. Geological Survey (USGS) Regional Aquifer System Analysis (RASA) program. Periodic revision of the model...
Geochemical and mineralogic investigation of elevated arsenic and trace element concentrations in glauconitic soils and sediments of the New Jersey Inner Coastal Plain
The U.S. Geological Survey New Jersey Water Science Center (USGS NJWSC) in cooperation with the New Jersey Department of Environmental Protection (NJDEP) has assembled this data release in support of ongoing USGS and NJDEP evaluations related to the occurrence and distribution of elevated trace elements, particularly arsenic (As) and vanadium (V), in Inner Coastal Plain soils and...
MODFLOW-NWT model used to evaluate the groundwater availability of the Columbia Plateau Regional Aquifer System, Washington, Oregon, and Idaho
A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of the hydrologic system to implement effective water-resource management strategies. The U.S. Geological Survey (USGS) Groundwater Resources Program assessed the groundwater availability as part of...

Digital elevations and extents of regional hydrogeologic units in the Northern Atlantic Coastal Plain aquifer system from Long Island, New York, to North Carolina
Digital geospatial datasets of the extents and top elevations of the regional hydrogeologic units of the Northern Atlantic Coastal Plain aquifer system from Long Island, New York, to northeastern North Carolina were developed to provide an updated hydrogeologic framework to support analysis of groundwater resources. The 19 regional hydrogeologic units were delineated by elevation grids...

Recovery of Ground-Water Levels From 1988 to 2003 and Analysis of Potential Water-Supply Management Options in Critical Area 1, East-Central New Jersey
Water levels in four confined aquifers in the New Jersey Coastal Plain within Water Supply Critical Area 1 have recovered as a result of reductions in ground-water withdrawals initiated by the State in the late 1980s. The aquifers are the Wenonah-Mount Laurel, the Upper and Middle Potomac-Raritan-Magothy, and Englishtown aquifer system. Because of increased water demand due to increased...

Sources of water to wells in updip areas of the Wenonah-Mount Laurel aquifer, Gloucester and Camden Counties, New Jersey
Since 1996, when the New Jersey Department of Environmental Protection (NJDEP) restricted ground-water withdrawals from the Potomac-Raritan-Magothy aquifer system in the southern New Jersey Coastal Plain as a result of excessive drawdown, Coastal Plain communities have been interested in developing alternate sources of water supply for their residents. The use of ground water from areas...

Use of a ground-water flow model to delineate contributing areas to the Puchack Well Field, Pennsauken township and vicinity, Camden county, New Jersey
The New Jersey Department of Environmental Protection (NJDEP) Well Head Protection Program, developed in response to the 1986 Federal Safe Drinking Water Act Amendments, requires delineation of Well Head Protection Areas (WHPA's), commonly called contributing areas, for all public and non-community water-supply wells in New Jersey. Typically, WHPA's for public community water-supply...

Simulation of ground-water flow in the Potomac-Raritan-Magothy aquifer system, Pennsauken Township and vicinity, New Jersey
The Potomac-Raritan-Magothy aquifer system is one of the primary sources of potable water in the Coastal Plain of New Jersey, particularly in heavily developed areas along the Delaware River. In Pennsauken Township, Camden County, local drinking-water supplies from this aquifer system have been contaminated by hexavalent chromium at concentrations that exceed the New Jersey maximum...

A hydrologic primer for New Jersey watershed management
The U.S. Geological Survey (USGS) and the N.J. Department of Environmental Protection (NJDEP), and many other agencies and organizations are striving to educate the public about New Jersey’s water resources. In 1996, the NJDEP began implementing a “watershed management approach” to maintain the physical, chemical, and biological integrity of New Jersey’s waters. This approach...

Hydrology of the unconfined aquifer system, Mullica River basin, New Jersey, 1991-92
The Kirkwood-Cohansey aquifer system, an unconfined aquifer system, is a major source of water in the Mullica River Basin in southern New Jersey. A water-level map was constructed from water levels measured in 197 wells and at 156 stream sites in the basin. Water levels in six observation wells were evaluated for seasonal fluctuations. The horizontal hydraulic conductivity of the...
