Potentiometric surface of the Aquia Aquifer in southern Maryland during September 1988
Frederick K. Mack, David C. Andreasen, Stephen E. Curtin, Judith C. Wheeler
1990, Water-Resources Investigations Report 90-4037
A map showing the potentiometric surface of the Aquia aquifer in the Paleocene Aquia Formation in southern Maryland during the fall of 1988 was constructed on the basis of water level measurements made at 84 observation wells. The potentiometric surface was above sea level near the northwestern boundary and outcrop...
The difference between the potentiometric surfaces of the Magothy Aquifer of September 1986 and September 1988 in southern Maryland
Frederick K. Mack, David C. Andreasen, Stephen E. Curtin, Judith C. Wheeler
1990, Water-Resources Investigations Report 90-4038
A map was prepared that shows the net change in the potentiometric surface of the Magothy aquifer (in the Cretaceous Magothy Formation) in southern Maryland from the fall of 1986 to the fall of 1988. The map, based on water level measurements from 79 observation wells, shows that during the...

Potentiometric surface of the Magothy Aquifer in southern Maryland during September 1988
Frederick K. Mack, David C. Andreasen, Stephen E. Curtin, Judith C. Wheeler
1990, Water-Resources Investigations Report 90-4040
A map showing the potentiometric surface of the Magothy aquifer in southern Maryland during the fall of 1988 was prepared from water-level measurements in 83 observation wells. The potentiometric surface was highest near the northwest boundary and outcrop area of the aquifer in topographically high locations of Anne Arundel and...
Mineral Resources of the Wabayuma Peak Wilderness Study Area, Mohave County, Arizona
Clay M. Conway, Jerry R. Hassemer, Daniel H. Knepper, James A. Pitkin, Robert C. Jachens, Mark L. Chatman
1990, Bulletin 1737-E
The Wabayuma Peak Wilderness Study Area (AZ-020-037/043), for which a mineral survey was requested by the U.S. Bureau of land Management, encompasses 40,118 acres in northwestern Arizona. Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources...
