Comparison of Hydrologic Data from Monroe County, Michigan, 1991-2001
J.R. Nicholas, Stephen P. Blumer, Rose M. McGowan
2001, Open-File Report 2001-498
In the summer of 2001, there were renewed concerns about the effects of quarry dewatering on nearby domestic ground-water supplies in Monroe County, Michigan. Reports of domestic wells “going dry” are not uncommon historically in Monroe County. Such reports have been linked to droughts, nearby irrigation, quarrying, and other large...

Assessment of volatile organic compounds in surface water at Canal Creek, Aberdeen Proving Ground, Maryland, November 1999–September 2000
Daniel J. Phelan, Lisa D. Olsen, Michael P. Senus, Tracey A. Spencer
2001, Open-File Report 2001-292
The purpose of this report is to describe the occurrence and distribution of volatile organic compounds in surface-water samples collected by the U.S. Geological Survey in the Canal Creek area of Aberdeen Proving Ground, Maryland, from November 1999 through September 2000. The report describes the differences between years with below...
Potentiometric surface of the Magothy aquifer in southern Maryland, September 1999
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2001, Open-File Report 2001-207
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 1999. The map, based on water level measurements in 61 wells, shows that the potentiometric surface during the 24-year...
Use of InSAR to identify land-surface displacements caused by aquifer-system compaction in the Paso Robles area, San Luis Obispo County, California, March to August 1997
David W. Valentine, Jill N. Densmore, Devin L. Galloway, Falk Amelung
2001, Open-File Report 2000-447
The population in San Luis Obispo County has grown steadily during the 1990s, and some land use has been converted from dry farming to grazing to irrigated vineyards and urban areas. Because insufficient surface-water supplies are available to meet the growing demand, ground-water pumpage has increased and the resulting water-level...
Potentiometric surface of the Magothy aquifer in southern Maryland, September 1999
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2001, Open-File Report 2001-206
This report presents a map showing the change in the potentiometric surface of the Lower Patapsco aquifer in the Lower Patapsco Formation of Cretaceous age in Southern Maryland for September 1990 and September 1999. The map, based on water?level measurements in 52 wells, shows that the change of the potentiometric...
Lead-rich sediments, Coeur d'Alene River Valley, Idaho: area, volume, tonnage, and lead content
