Microorganisms in stormwater; a summary of recent investigations
Gail E. Mallard
1980, Open-File Report 80-1198
All storm runoff contains a variety of bacteria, including total coliform, fecal coliform, and fecal streptococci, which are derived from the land over which the water flows. Most total coliform are native soil organisms, whereas the fecal coliform and fecal streptococci originate from the feces of wild and domestic animals....
Potential for using the Upper Coachella Valley ground-water basin, California, for storage of artificially recharged water
Michael J. Mallory, Lindsay A. Swain, Stephen J. Tyley
1980, Open-File Report 80-599
This report presents a preliminary evaluation of the geohydrologic factors affecting storage of water by artificial recharge in the upper Coachella Valley, Calif. The ground-water basin of the upper Coachella Valley seems to be geologically suitable for large-scale artificial recharge. A minimum of 900 ,000 acre-feet of water could probably...
Selected chemical quality characteristics in streams of Kentucky, 1970-1975
J.F. Santos
1980, Water-Resources Investigations Report 79-21
Generalized maps of average dissolved solids, hardness and nitrate concentrations of water in streams throughout Kentucky were prepared from data collected at more than 100 sites from 1970 to 1975. Average dissolved solids concentrations seldom exceed 250 milligrams per liter. Hardness, mostly of calcium magnesium origin, generally ranges from 60...
Hydrogeology of the Seldovia area, Alaska
Gordon L. Nelson, Wesley R. Danskin
1980, Open-File Report 80-952
Surficial materials in the Seldovia area, Alaska, are mapped as glacial drift over sedimentary bedrock, glacial drift over igneous and metamorphic bedrock, valley-bottom, alluvium, alluvial fan deposits, beach and intertidal deposits, and peat. Unconsolidated materials are generally less than 10 feet thick except in well-drained glacial deposits along the Seldovia-Jakolof...
Oilspill analysis for the Cook Inlet and Shelikof Strait (proposed sale 60) Outer Continental Shelf lease area
Robert P. LaBelle, William B. Samuels, Kenneth J. Lanfear
1980, Open-File Report 80-863
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Cook Inlet and Shelikof Strait (Proposed Sale 60) Outer Continental Shelf (OCS) lease area. The probability of spill occurrences, likely movement of oil slicks, and locations of resources vulnerable to...
Graded storm sand layers offshore from the Yukon Delta, Alaska
C. Hans Nelson
1980, Open-File Report 80-712
The northern Bering Sea has a history of severe storm surges. The most recent, and perhaps the worst in historical times, occurred in November, 1974 (Fathauer, 1975). Evidence of storm surge events is exhibited in sea-floor stratigraphy as well as shoreline flooding and indicates that significant widespread changes in sea-floor...
Sediment yields of New Jersey streams
S. M. Hindall, D.W. Jungblut
1980, Open-File Report 80-432
Sediment data from 76 stream-gaging sites throughout New Jersey indicate that suspended sediment yields in New Jersey streams range from less than 10 tons per square mile per year to about 700 tons per square mile per year. Sixty to 100 percent of the material transported as suspended sediment is...
Bedrock topography of southwest Iowa
Lyle Sendlein, Jack L. Gilmore
1980, IMAP 1222
The bedrock in Iowa (Hershey, 1969) is generally overlain by unconsolidataed deposits consisting of glacial drift, alluvium, and loess. Loess deposits are most extensive in areas bordering the Missouri River flood plain, attaining a thickness of over 200ft in some places. The total thickness of the unconsolidated sediments ranges from...
Potentiometric map of the Lower Wilcox Aquifer in Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-597
The potentiometric map of the lower Wilcox aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area of the lower Wilcox aquifer...
Lemhi Pass drilling project, Montana
Mortimer Hay Staatz
1980, Open-File Report 80-312
The Lemhi Pass district has the largest thorium resources of any vein district in the United States (Staatz and others, 1979, p. 10). Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped...
