Gregory S Cherry
Gregory Cherry is a Hydrologist with the South Atlantic Water Science Center in Norcross, Ga., with more than 30 years experience in groundwater related issues.
Greg grew up on the west coast in the Bay Area and became hooked on geology after the eruption of Mount St. Helens in May, 1980. A sailboat adventure with family in the U.S. Virgin Islands sparked interest in island hydrology and craving life in the tropics. After graduating with a BS in geology in 1986, an early assignment with Bechtel Corporation on a Superfund site in Vega Alta, Puerto Rico, eventually led him to begin his career with the U.S. Geological Survey in the Caribbean District (before offices were called Water Science Centers). Thus a twelve-year tenure began in Puerto Rico that led to a search for fresh groundwater resources in the outlying islands. During that period, Greg served as the chief of the St. Croix Field Office in the U.S. Virgin Islands, which focused on numerous monitoring projects. Fresh groundwater resources on the main island of Puerto Rico are critically important and led to groundwater modeling opportunities along the North Coast Province near the municipios of Manatí and Vega Baja. In 2002, Greg moved to Atlanta, Georgia, to gain an understanding of groundwater-flow patterns near the Savannah River Site and track potential contamination. I always feel fortunate that the majority of my work has remained focused on issues relating to groundwater and groundwater management.
Currently serving as Project Chief for the Brunswick/Glynn County Cooperative Water Program, which monitors saltwater contamination in the Upper Floridan aquifer (UFA). This ongoing work combines groundwater modeling with annual water-quality sampling to assess saltwater movement near the City of Brunswick. Utilized regional groundwater-flow model of coastal Georgia and parts of South Carolina and Florida to determine changes in the UFA caused by increased pumping at U.S. Army Fort Stewart and Hunter Army Airfield, and for the cities of Pooler, Rincon, and Berwick located in Chatham County, Georgia. Part of a team of agencies led by South Carolina Department of Natural Resources using groundwater-modeling techniques to forecast future groundwater availability in the Edisto River basin.

Simulation and Particle-Tracking Analysis of Selected Ground-Water Pumping Scenarios at Vogtle Electric Generation Plant, Burke County, Georgia
The source of ground water to production wells at Vogtle Electric Generation Plant (VEGP), a nuclear power plant in Burke County, Georgia, was simulated under existing (2002) and potential future pumping conditions using an existing U.S. Geological Survey (USGS) MODFLOW ground-water flow model of a 4,455-square-mile area in the Coastal Plain of Georgia and South Carolina.

ClarkeU.S. Geological Survey Georgia Water Science Center and City of Brunswick–Glynn County Cooperative Water Program— Summary of activities, July 2005 through June 2006
Since 1959, the U.S. Geological Survey has conducted a cooperative water resources program (CWP) with the City of Brunswick and Glynn County in the Brunswick, Georgia, area. Since the late 1950s, the salinity of ground water in the Upper Floridan aquifer near downtown Brunswick, Georgia, has been increasing, and its occurrence has been detected across an area of increasing size.

Ground-water flow under 2002 hydrologic conditions was evaluated in an eight-county area in Georgia and South Carolina near the Savannah River Site (SRS), by updating boundary conditions and pumping rates in an existing U.S. Geological Survey (USGS) ground-water model.

A regional MODFLOW ground-water flow model of parts of coastal Georgia, Florida, and South Carolina was used to evaluate the effects of current and hypothetical groundwater withdrawal, and the relative effects of pumping in specific areas on ground-water flow in the Upper Floridan aquifer near Fort Stewart and Hunter Army Airfield (HAAF), coastal Georgia.
