Test well BFT-2055 was drilled through the entire thickness of Coastal Plain sediments beneath central Hilton Head Island, South Carolina, and terminated in bedrock at a depth of 3833 feet. The well was drilled to evaluate the hydraulic properties of the Cretaceous formations beneath Hilton Head Island as a potential source of supplemental water to supplies currently withdrawn from the...

A methodology was developed to evaluate and map the contamination potential or aquifer sensitivity of the upper groundwater flow system of a portion of the General Separations Area (GSA) at the Department of Energy's Savannah River Site (SRS) in South Carolina. A Geographic Information System (GIS) was used to integrate diverse subsurface geologic data, soils data, and hydrology...

Shallow, anaerobic groundwater near a former manufactured-gas plant (MGP) in Charleston, South Carolina, USA, contains mono- and polycyclic aromatic hydrocarbons (MAHs and PAHs, respectively). Between 1994 and 1997, a combination of field, laboratory, and numerical-flow and transport-model investigations were made to assess natural attenuation processes affecting MAH and PAH...

Introduction High levels of fecal-indicator bacteria in rivers and streams can indicate the possible presence of pathogenic (disease-causing) microorganisms. Cholera, typhoid fever, bacterial dysentery, infectious hepatitis, and cryptosporidiosis are some of the well known waterborne diseases that spread through water contaminated and fecal matter. Eye, ear, nose, and throat infections...

Introduction This report summarizes the available pesticide data for surface waters in the Santee River Basin and coastal drainages (SANT) study area, as part of the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Data from the U.S. Environmental Protection Agency Storage and Retrieval database and data collected by the USGS in the SANT NAWQA study area...

Water-resources data for the 1997 water year for Georgia consists of discharge records for 123 gaging stations; stage for 23 gaging stations; stage and contents for 18 lakes and reservoirs; water quality for 202 continuing-record stations; and peak stage and discharge only for 77 crest-stage partial-record stations; and water levels of 24 observation wells. The data for the Gulf of...

This report is intended to summarize major findings that emerged between 1992 and 1995 from the water-quality assessment of the Georgia-Florida Coastal Plain Study Unit and to relate these findings to water-quality issues of regional and national concern. The information is primarily intended for those who are involved in water-resource management. Yet, the information contained here may...

Ground-water flow and stream-aquifer relations were simulated for seven aquifers in Coastal Plain sediments in the vicinity of the U.S. Department of Energy, Savannah River Site (SRS), in Georgia and South Carolina to evaluate the potential for ground water containing hazardous materials to migrate from the SRS into Georgia through aquifers underlying the Savannah River (trans-river flow...

Surface- and ground-water resources in the Savannah, Georgia, area were evaluated for potential water-supply development. Stream-discharge and water-quality data were analyzed for two major streams considered to be viable water-supply sources. A ground-water flow model was developed to be used in conjunction with other previously calibrated models to simulate the effects of additional...
