Catherine R. McMasters, Darrell G. Herd, Constance K. Throckmorton, Linda E. Heusser
1987, Miscellaneous Field Studies Map 1461
In September 1977, four cores were recovered by shallow auger drilling from Hollister Valley, California, near the Calaveras fault. The wells were drilled to search for evidence that Hollister Valley may have been occupied by a large lake during the late Pleistocene or Holocene. This small valley, near Monterey Bay,...

Water-quality data-collection activities in Colorado and Ohio; Phase II, Evaluation of 1984 field and laboratory quality-assurance practices
Carolyn J. Oblinger Childress, Thomas H. Chaney, Donna Myers, J. Michael Norris, Janet Hren
1987, Open-File Report 87-33
Serious questions have been raised by Congress about the usefulness of water-quality data for addressing issues of regional and national scope and, especially, for characterizing the current quality of the Nation's streams and ground water. In response, the U.S. Geological Survey has undertaken a pilot study in Colorado and Ohio...
Drainage areas in the James River basin in eastern South Dakota
Rick D. Benson, M.E. Freese, Frank D. Amundson, V.J. Wipf
1987, Open-File Report 87-572
The James River of eastern South Dakota contains an important surface-water supply for the agricultural economy within the basin. Proposed water-resource development has prompted numerous hydrologic studies of the James River. To aid in planning for future development, the map delineates all named stream basins, and all unnamed basins larger...
U.S. Geological Survey program on toxic waste--ground-water contamination; proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987
Bernard J. Franks, editor(s)
1987, Open-File Report 87-109
Problems of ground-water contamination from leaking surface impoundments are common in surficial aquifers, and are a subject of increasing concern and attention. A potentially widespread contamination problem involves organic chemicals used in wood-preserving processes. Creosote is the most extensively used industrial preservative in the United States today, with more than...
Test plan for 32-bit microcomputers for the Water Resources Division; Chapter A, Test plan for acquisition of prototype 32-bit microcomputers

1987, Open-File Report 87-455
The Water Resources Division (WRD) of the U.S. Geological Survey is evaluating 32-bit microcomputers to determine how they can complement, and perhaps later replace, the existing network of minicomputers. The WRD is also designing a National Water Information System (NWIS) that will combine and integrate the existing National Water Data...
