Biography
I am currently managing the USGS work on the National Ground Water Monitoring Network (NGWMN). The NGWMN is a compilation of selected wells from existing Federal and State monitoring efforts to create a network to allow assessment of long-term water-level and water-quality trends at a National scale. The Network was created by the Subcommittee on Ground Water (SOGW) of the Federal Advisory Committee on Water Information (ACWI). My work involves coordinating with the SOGW and managing the USGS work on the NGWMN. Information on the NGWMN is available at: http://cida.usgs.gov/ngwmn/
Previously I served as the New Jersey Water Center Groundwater Specialist and worked on groundwater projects of my own. As Groundwater specialist, I worked with groundwater projects to provide technical guidance, worked on the New Jersey Water-level monitoring network, and oversaw work on the Center groundwater databases. My project work involved groundwater modeling in support of water supply issues. Most of my work has been in the Coastal Plain aquifer system of New Jersey.
Specific areas of interest are; groundwater modeling, groundwater databases, GIS, Water use data, water availability assesment, and groundwater monitoring networks.
Science and Products
Aquifers: Map of the Principal Aquifers of the United States
The areal and vertical location of the major aquifers is fundamental to the determination of groundwater availability for the Nation. The map, which is derived from the Ground Water Atlas of the United States, indicates the areal extent of the uppermost principal aquifers on a national scale.
National Ground-Water Monitoring Network (NGWMN) Data Portal
The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The Portal contains current and historical data including water levels, water quality, lithology, and well construction.
Simulated effects of alternative withdrawal strategies on groundwater flow in the unconfined Kirkwood-Cohansey aquifer system, the Rio Grande water-bearing zone, and the Atlantic City 800-foot sand in the Great Egg Harbor and Mullica River Basins, New Jersey
Groundwater is essential for water supply and plays a critical role in maintaining the environmental health of freshwater and estuarine ecosystems in the Atlantic Coastal basins of New Jersey. The unconfined Kirkwood-Cohansey aquifer system and the confined Atlantic City 800-foot sand are major sources of groundwater in the area, and each faces...

Future Water-Supply Scenarios, Cape May County, New Jersey, 2003-2050
Stewards of the water supply in New Jersey are interested in developing a plan to supply potable and non-potable water to residents and businesses of Cape May County until at least 2050. The ideal plan would meet projected demands and minimize adverse effects on currently used sources of potable, non-potable, and ecological water supplies. This...

Summary of the Ground-Water-Level Hydrologic Conditions in New Jersey 2006
Ground water is one of the Nation's most important natural resources. It provides about 40 percent of our Nation's public water supply. Currently, nearly one-half of New Jersey's drinking-water is supplied by over 300,000 wells that serve more than 4.3 million people (John P. Nawyn, U.S. Geological Survey, written commun., 2007). New Jersey's...

Simulation of proposed increases in ground-water withdrawals on the Atlantic City 800-foot sand, New Jersey coastal plain
The confined Atlantic City 800-foot sand and the unconfined Kirkwood-Cohansey aquifer system (surficial aquifer) are major sources of water for southeastern New Jersey. Because of recent concerns about streamflow depletion resulting from ground-water withdrawals and the potential ecological effects on stream habitat in the area, the focus on...
Pope, Daryll A. 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...
Pope, Daryll A.; Watt, Martha K. 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...

Real-time ground-water-level monitoring in New Jersey, 2002
This network was created to provide data to indicate water-level trends in shallow ground-water systems within the State of New Jersey and to make the data available in the shortest time possible. The wells in this network are located throughout New Jersey (fig. 1) and were chosen because they are completed in shallow aquifers (table 1). The...

Real-time ground-water-level monitoring in New Jersey
A network of seven observation wells that transmit ground-water-level data on a real-time basis through satellite telemetry is operating (started May 2001) in New Jersey through a cooperative effort of the U.S. Geological Survey (USGS) and the New Jersey Department of Environmental Protection (NJDEP). The water-level data from these observation...

Simulation of ground-water flow and movement of the freshwater-saltwater interface in the New Jersey coastal plain
The confined aquifers of the New Jersey Coastal Plain are sands that range in thickness from 50 to 600 feet and are separated by confining units. The confining units are composed of silts and clays that range in thickness from 500 to 1,000 feet. The aquifers are recharged by precipitation on their outcrop areas. This water then flows laterally...

Occurrence of the gasoline additive MTBE in shallow ground water in urban and agricultural areas
Methyl tert-butyl ether (MTBE) is a volatile organic compound (VOC) derived from natural gas that is added to gasoline either seasonally or year round in many parts of the United States to increase the octane level and to reduce carbon monoxide and ozone levels in the air. In 1993, production of MTBE ranked second among all organic chemicals...

Hydrogeology, simulation of regional ground-water flow, and saltwater intrusion, Potomac-Raritan-Magothy Aquifer System, Northern Coastal Plain of New Jersey
The Potomac-Raritan-Magothy aquifer system in Middlesex and Monmouth Counties in the northern Coastal Plain of New Jersey consists primarily of unconsolidated Cretaceous sediments, which are divided into the upper and middle aquifers and confining units. These units, which strike northeastsouthwest along the Fall Line, dip and thicken to the...
