Sensitivity of ground water to contamination in Lawrence County, South Dakota
Larry D. Putnam
2000, Water-Resources Investigations Report 2000-4103
Ground-water supplies in Lawrence County, South Dakota, can be contaminated by agricultural, urban, suburban, commercial, and industrial land uses. To address this issue, the U.S. Geological Survey in cooperation with Lawrence County and the City of Spearfish mapped the sensitivity of ground water to contamination in Lawrence County. Sensitivity of ground...
Geologic map and database of the Salem East and Turner 7.5 minute quadrangles, Marion County, Oregon: A digital database
Terry L. Tolan, Marvin H. Beeson, Christopher B. DuRoss
2000, Open-File Report 2000-351
The Salem East and Turner 7.5-minute quadrangles are situated in the center of the Willamette Valley near the western margin of the Columbia River Basalt Group (CRBG) distribution. The terrain within the area is of low to moderate relief, ranging from about 150 to almost 1,100-ft elevation. Mill Creek flows...
Interim report on the scientific investigations in the Animas River watershed, Colorado to facilitate remediation decisions by the U.S. Bureau of Land Management and the U.S. Forest Service, March 29, 2000 meeting, Denver, Colo.
Water Resources Division, U.S. Geological Survey
2000, Open-File Report 2000-245
INTRODUCTION The joint U.S. Department of the Interior and U.S. Department of Agriculture Abandoned Mine Lands Initiative (AMLI) was developed as a collaborative effort between the Federal land management agencies (FLMA, that is the U.S. Bureau of Land Management and the U.S. Forest Service) and the U.S. Geological Survey (USGS) in 1996. The stated...
Physical characteristics of stream subbasins in the Long Prairie River basin, central Minnesota
Christopher A. Sanocki, Brian C. Fischer
2000, Open-File Report 2000-232
Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Long Prairie River Basin, located in central Minnesota, are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin covered only by lakes,...
Use of borehole geophysical logs for improved site characterization at Naval Weapons Industrial Reserve Plant, Dallas, Texas
Roberto Anaya, Christopher L. Braun, Eve L. Kuniansky
2000, Water-Resources Investigations Report 2000-4150
A shallow alluvial aquifer at the Naval Weapons Industrial Reserve Plant near Dallas, Texas, has been contaminated by organic solvents used in the fabrication and assembly of aircraft and aircraft parts. Natural gamma-ray and electromagnetic-induction log data collected during 1997 from 162 wells were integrated with existing lithologic and cone-penetrometer...
Evaluation of a Method of Estimating Low-Flow Frequencies from Base-Flow Measurements at Indiana Streams
John Thomas Wilson
2000, Water-Resources Investigations Report 2000–4063
A mathematical technique of estimating low-flow frequencies from base-flow measurements was evaluated by using data for streams in Indiana. Low-flow frequencies at low-flow partial-record stations were estimated by relating base-flow measurements to concurrent daily flows at nearby streamflow-gaging stations (index stations) for which low-flow- frequency curves had been developed. A...
Ground-water resources of Tinian, Commonwealth of the Northern Mariana Islands
Stephen B. Gingerich, Daniel S. Yeatts
2000, Water-Resources Investigations Report 2000-4068
Tinian, which lies in the western Pacific Ocean at latitude 15°N and longitude 145°W (fig. 1), is the second largest island (39.2 mi2) in the Commonwealth of the Northern Mariana Islands (CNMI). Fresh ground water is obtained from shallow wells that tap the surface of a freshwater lends found in...
Delineation of groundwater recharge areas, western Cape Cod, Massachusetts
John P. Masterson, Donald A. Walter
2000, Water-Resources Investigations Report 2000-4000
The unconfined sand-and-gravel aquifer in western Cape Cod, Massachusetts, which is the sole source of water supply for the communities in the area, is recharged primarily from precipitation. The rate of recharge from precipitation is estimated to be about 26 inches per year (in/yr), or about 60 percent of the...
Physical characteristics of stream subbasins in the Sauk River basin, central Minnesota
Christopher A. Sanocki, Brian C. Fischer
2000, Open-File Report 2000-233
Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Sauk River Basin, located in central Minnesota, are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin covered only by lakes, the...
Contaminants and drinking-water sources in 2001; recent findings of the U. S. Geological Survey
G. G. Patterson, M. J. Focazio
2000, Open-File Report 2000-510
As the Nation's principal earth-science agency, the U.S. Geological Survey (USGS) studies numerous issues related to contamination of drinking-water sources. The work includes monitoring to determine the spatial and temporal distribution of contaminants; research to determine sources, transport, transformations, and fate of contaminants, and assessments of vulnerability. Much of the...
Computer-model analysis of ground-water flow and simulated effects of contaminant remediation at Naval Weapons Industrial Reserve Plant, Dallas, Texas
Rene A. Barker, Christopher L. Braun
2000, Water-Resources Investigations Report 2000-4197
In June 1993, the Department of the Navy, Southern Division Naval Facilities Engineering Command (SOUTHDIV), began a Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) of the Naval Weapons Industrial Reserve Plant (NWIRP) in north-central Texas. The RFI has found trichloroethene, dichloroethene, vinyl chloride, as well as chromium, lead,...
Characterization and simulation of ground-water flow in the Kansas River Valley at Fort Riley, Kansas, 1990-98
Nathan C. Myers
2000, Water-Resources Investigations Report 2000-4096
Hydrologic data and a ground-water flow model were used to characterize ground-water flow in the Kansas River alluvial aquifer at Fort Riley in northeast Kansas. The ground-water flow model was developed as a tool to project ground-water flow and potential contaminant-transport paths in the alluvial aquifer on the basis of...
