Potentiometric surface map of the Magothy aquifer in southern Maryland, September, 2003 Potentiometric surface map of the Magothy aquifer in southern Maryland, September, 2003
This report presents a map showing the potentiometric surface of the Magothy aquifer in the Magothy Formation of Upper Cretaceous age in Southern Maryland during September 2002. The map is based on water-level measurements in 79 wells. The highest measured water level was 83 feet above sea level near the northern boundary and outcrop area of the aquifer in the north-central part of Anne...

Potentiometric surface of the Aquia Aquifer in southern Maryland, September 2003 Potentiometric surface of the Aquia Aquifer in southern Maryland, September 2003
This report presents a map showing the potentiometric surface of the Aquia aquifer in the Aquia Formation of Paleocene age in Southern Maryland during September 2003. The map is based on water-level measurements in 91 wells. The highest measured water level was 40 feet above sea level near the northern boundary and outcrop area of the aquifer in the central part of Anne Arundel County...

The difference between the potentiometric surfaces of the Magothy aquifer, September 1975 and September 2003 in southern Maryland The difference between the potentiometric surfaces of the Magothy aquifer, September 1975 and September 2003 in southern Maryland
This report presents a map showing the change in the potentiometric surface of the Magothy aquifer in the Magothy Formation of Cretaceous age in Southern Maryland for September 1975 and September 2003. The map, based on water level measurements in 51 wells, shows that during the 28-year period, the potentiometric surface had no change at the outcrop area, which is in the northernmost...

The difference between the potentiometric surfaces of the Aquia Aquifer, September 1982 and September 2003 in southern Maryland The difference between the potentiometric surfaces of the Aquia Aquifer, September 1982 and September 2003 in southern Maryland
This report presents a map showing the change in the potentiometric surface of the Aquia aquifer in the Aquia Formation of Paleocene age in Southern Maryland for September 1982 and September 2003. The map, based on water level measurements in 56 wells, shows that the potentiometric surface during the 21-year period declined from zero in the northernmost part of the study area, which is...

Ground-water vulnerability to nitrate contamination at multiple thresholds in the mid-Atlantic region using spatial probability models Ground-water vulnerability to nitrate contamination at multiple thresholds in the mid-Atlantic region using spatial probability models
The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency?s Regional Vulnerability Assessment Program, has developed a set of statistical tools to support regional-scale, ground-water quality and vulnerability assessments. The Regional Vulnerability Assessment Program?s goals are to develop and demonstrate approaches to comprehensive, regional-scale...

A surficial hydrogeologic framework for the Mid-Atlantic Coastal Plain A surficial hydrogeologic framework for the Mid-Atlantic Coastal Plain
A surficial hydrogeologic framework was developed for the Mid-Atlantic Coastal Plain, from New Jersey through North Carolina. The framework includes seven distinct hydrogeologic subregions within which the primary natural physical factors affecting the flow and chemistry of shallow ground water and small streams are relatively consistent. Within most subregions, the transport of...

Analytical results from ground-water sampling using a direct-push technique at the Dover National Test Site, Dover Air Force Base, Delaware, June-July 2001 Analytical results from ground-water sampling using a direct-push technique at the Dover National Test Site, Dover Air Force Base, Delaware, June-July 2001
A joint study by the Dover National Test Site and the U.S. Geological Survey was conducted from June 27 through July 18, 2001 to determine the spatial distribution of the gasoline oxygenate additive methyl tert-butyl ether and selected water-quality constituents in the surficial aquifer underlying the Dover National Test Site at Dover Air Force Base, Delaware. The study was conducted to...

A hydrogeologic model of stratiform copper mineralization in the Midcontinent Rift System, Northern Michigan, USA A hydrogeologic model of stratiform copper mineralization in the Midcontinent Rift System, Northern Michigan, USA
This paper presents a suite of two-dimensional mathematical models of basin-scale groundwater flow and heat transfer for the middle Proterozoic Midcontinent Rift System. The models were used to assess the hydrodynamic driving mechanisms responsible for main-stage stratiform copper mineralization of the basal Nonesuch Formation during the post-volcanic/pre-compressional phase of basin...
