Analyzing thematic maps and mapping for accuracy
G.H. Rosenfield
1982, Open-File Report 82-239
Two problems which exist while attempting to test the accuracy of thematic maps and mapping are: (1) evaluating the accuracy of thematic content, and (2) evaluating the effects of the variables on thematic mapping. Statistical analysis techniques are applicable to both these problems and include techniques for sampling the data...
Reconnaissance of ground-water quality, eastern Snake River basin, Idaho
D. J. Parliman
1982, Water-Resources Investigations Report 82-4004
Water-quality, geologic, and hydrologic data were collected for 165 wells in the eastern Snake River basin, Idaho. Water-quality characteristics analyzed include specific conductance, pH, water temperature, major dissolved cations and anions, and coliform bacteria. Ground water from aquifers in all rock units is generally composed of calcium, magnesium, and bicarbonate...
Specification for procurement of water-level sensing instrumentation, specification number HIF-I-1
D.H. Rapp
1982, Open-File Report 82-89
This specification is to communicate to instrument manufacturers the U.S. Geological Survey 's requirements. It covers systems for sensing the elevation of the water surface on open channels, rivers, lakes, reservoirs, storm-sewer pipes, and observation wells at Survey data-collection sites. The signal output (mechanical or electrical) must meet the signal...
Aliphatic Hydrocarbons in Surface Sediments of Willapa Bay and Grays Harbor, Washington
J. B. Rapp, K.A. Kvenvolden, H.E. Clifton
1982, Open-File Report 82-609
Willapa Bay and Grays Harbor are two adjacent estuaries along the coast of Washington state. Willapa Bay is a recreational area minimally affected by industry; Grays Harbor, on the other hand, is moderately industrialized. Aliphatic hydrocarbons in surface sediments from these two estuaries reflect the differences in human activities. For...
Results of hydrologic tests and water-chemistry analyses, wells H-5A, H-5B, and H-5C, at the proposed Waste Isolation Pilot Plant site, southeastern New Mexico
Kevin F. Dennehy, Jerry W. Mercer
1982, Water-Resources Investigations Report 82-19
Data were collected during hydrologic testing at wells H-5A, H-5B, and H-5C in the northeastern part of the proposed Waste Isolation Pilot Plant site in southeastern New Mexico. The three water-bearing zones tested, the Magenta and Culebra Dolomite Members of the Rustler Formation and the Rustler Formation-Salado Formation contact, yield...
An oilspill risk analysis for the Mid-Atlantic (proposed sale 76) outer continental shelf lease area
W.B. Samuels, Dorothy Hopkins
1982, Open-File Report 82-27
An oilspill risk analysis was conducted for the mid-Atlantic (proposed sale 76) Outer Continental Shelf (OCS) lease area. The analysis considered: the probability of spill occurrences based on historical trends; likely movement of oil slicks based on a climatological model; and locations of environmental resources which could be vulnerable to...
Potential impacts of a proposed reservoir on hydrologic and water-quality conditions in Little Rush Creek watershed, Fairfield County, Ohio
Janet Hren, R.L. Jones
1982, Open-File Report 82-109
Water-quality and discharge measurements were made at three sites on Indian Run and one site on Little Rush Creek between February and December, 1979. Indian Run was observed above and below the U.S. Soil Conservation Service Reservoir, VI-D. Little Rush Creek was observed 1.1 miles downstream from the proposed U.S....
Dissolved-solids concentrations of ground water in the Sacramento Valley, California
Ronald P. Fogelman
1982, Hydrologic Atlas 645
The general quality of the ground water in the Sacramento Valley , Calif., in terms of dissolved-solids concentration is considered good for irrigation, domestic, and most other uses. This map shows the distribution of dissolved-solids concentrations and is based on about 1,330 chemical analyses collected from about 900 wells between...
