Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of selected carbamate pesticides in water by high-performance liquid chromatography
S.L. Werner, S.M. Johnson
1994, Open-File Report 93-650
As part of its primary responsibility concerning water as a national resource, the U.S. Geological Survey collects and analyzes samples of ground water and surface water to determine water quality. This report describes the method used since June 1987 to determine selected total-recoverable carbamate pesticides present in water samples. High-...
Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1991-92
R. G. Garrett
1994, Open-File Report 94-27
Water-quality measurements were made at six sites in or near North Carolina?s Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations. In the Pamlico River...
Effects of agricultural land-management practices on water quality in northeastern Guilford County, North Carolina, 1985-90
D.A. Harned
1994, Open-File Report 94-60
The effects of different agricultural land-management practices on sediment, nutrients, and selected pesticides in surface water, and on nutrients and pesticides in ground water were studied in four small basins in the Piedmont of North Carolina. The basins included two adjacent basins in row-crop fields, a mixed land-use basin, and...
Water resources data, Missouri, water year 1994
H.L. Reed, T.J. Perkins, G.L. Gray Jr.
1994, Water Data Report MO-94-1
The U.S. Geological Survey, Water Resources Division, in cooperation with local, State, and Federal agencies and organizations, obtains a large quantity of data pertaining to the water resources of Missouri each water year (October 1 to September 30). These data, accumulated during the water years, constitute a valuable data base...
Effects of acid deposition on dissolution of carbonate stone during summer storms in the Adirondack Mountains, New York, 1987-89
Paul F. Schuster, Michael M. Reddy, S.I. Sherwood
1994, Water-Resources Investigations Report 93-4189
This study is part of a long-term research program designed to identify and quantify acid rain damage to carbonate stone. Acidic deposition accelerates the dissolution of carbonate-stone monuments and building materials. Sequential sampling of runoff from carbonate-stone (marble) and glass (reference) microcatchments in the Adirondack Mountains in New York State...
Lateral movement and stability of channel banks near four highway crossings in southwestern Mississippi
D. Phil Turnipseed
1994, Water-Resources Investigations Report 94-4035
Channel meandering in alluvial streams has caused localized channel instability that has resulted in bridge failure and loss of human life in Mississippi. The U.S. Geological Survey, in coopera- tion with the Mississippi Department of Transpor- tation, conducted a study to develop a better methodology for defining and estimating channel...
Synopsis of discussion session on physicochemical factors affecting toxicity
R.J. Erickson, T.D. Bills, J. R. Clark, D.J. Hansen, J. Knezovich
J.L. Hamelink, P.F. Landrum, H.L. Bergman, W.H. Benson, editor(s)
1994, Book chapter, Bioavailability physical, chemical and biological interactions
The paper documents the workshop discussion regarding the role of these factors in altering toxicity. For each factor, the nature, magnitude, and uncertainty of its empirical relation to the toxicity of various chemicals or chemical classes is discussed. Limitations in the empirical database regarding the variety of species and endpoints...

Ground-water levels and directions of flow near the Industrial Excess Landfill, Uniontown, Ohio, March 1994
Denise H. Dumouchelle, E. Scott Bair
1994, Water-Resources Investigations Report 94-4136
Industrial Excess Landfill (IEL), a U.S. Environmental Protection Agency Superfund site, is a closed landfill in northeastern Ohio. In March 1994, personnel from the U.S. Geological Survey, Ohio Environmental Protection Agency, and PRC Environmental Management, Inc., measured water levels in 149 wells in the area. Surface-water altitudes were measured at...
Ground water and the rural homeowner
Roger M. Waller
1994, Report
As the salesmen sang in the musical The Music Man, "You gotta know the territory." This saying is also true when planning to buy or build a house. Learn as much as possible about the land, the water supply, and the septic system of the house before buying or building....
