Water resources of the White Earth Indian Reservation, northwestern Minnesota
J. F. Ruhl
1989, Water-Resources Investigations Report 89-4074
Water resources in the White Earth Indian Reservation meet the present (1988) needs for potable supply and other household uses and provide valuable ecological, recreational, and aesthetic benefits. Total annual water use in the Reservation is about 460 million gallons per year. Domestic supply from privately owned wells and municipal...
Water quality and supply on Cortina Rancheria, Colusa County, California
E.B. Yates
1989, Water-Resources Investigations Report 89-4004
Cortina Rancheria covers an area of 1 sq mi in Colusa County, California, near the western edge of the Sacramento Valley. Local sources of water for residents of the rancheria are of poor quality or limited availability. Domestic needs are presently met by water from a hand-dug well and from...
Bedrock geology of the Bristol quadrangle, Hartford, Litchfield, and New Haven Counties, Connecticut
Howard E. Simpson
1989, Bulletin 1573
Metamorphosed strata of sedimentary origin underlie the upland surface of western Connecticut, and nonmetamorphosed sedimentary strata underlie the adjacent lowland surface of central Connecticut. The metamorphic rocks consist chiefly of micaceous schists and gneisses, with minor amounts of pegmatite, amphibolite, and metaquartzite. These rocks represent three formations. They are, in...
Depositional environments of the Upper Triassic Chinle Formation in the eastern San Juan Basin and vicinity, New Mexico. Trace fossils and mollusks from the upper member of the Wanakah Formation, Chama Basin, New Mexico; evidence for a lacustrine origin. Stratigraphy, facies, and paleotectonic history of Mississippian rocks in the San Juan Basin of northwestern New Mexico and adjacent areas
Russell F. Dubiel, Jennie L. Ridgley, Augustus K. Armstrong, Lee D. Holcomb
1989, Bulletin 1808-B-D

Geologic map of the Latir Volcanic Field and adjacent areas, northern New Mexico
P. W. Lipman, J. C. Reed Jr.
1989, IMAP 1907
This map was first published as a printed edition in 1989. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files. This map encompasses all or parts of ten 7.5 minute quadrangles in the Taos...
Sources and concentrations of dissolved solids and selenium in the San Joaquin River and its tributaries, California, October 1985 to March 1987
D.G. Clifton, R. J. Gilliom
1989, Water-Resources Investigations Report 88-4217
Sources and concentrations of dissolved solids and selenium in the San Joaquin River and its tributaries, California, were assessed by a mass-balance approach to determine the effects of tile-drain water and irrigation-return flows on the river. The study included low-flow periods from October 1985 to mid-February 1986 and mid-May 1986...
Geohydrology of the Foothill ground-water basin near Santa Barbara, California
J. R. Freckleton
1989, Water-Resources Investigations Report 89-4017
Geohydrologic data presented in this report indicate that the East Subbasin of the Goleta groundwater basin and Storage Unit II of the Santa Barbara groundwater basin should be considered as a separate groundwater basin, which is referred to as the Foothill groundwater basin in this report. The 4.5 sq-mi Foothill...
Aquifers in Cretaceous rocks of the central Coastal Plain of North Carolina
M. D. Winner Jr., W.L. Lyke
1989, Water-Resources Investigations Report 87-4178
Aquifers in rocks of Cretaceous age are the major source of groundwater for public supplies in the central Coastal Plain. These aquifers consist of sand, gravel, and limestone beds of the Peedee, Black Creek, and the upper and lower Cape Fear aquifers, each separated by a confining unit composed of...
Preliminary hydrogeologic evaluation of the Cincinnati Arch region for underground high-level radioactive waste disposal, Indiana, Kentucky, and Ohio
O. B. Lloyd, R. W. Davis
1989, Water-Resources Investigations Report 88-4098
Preliminary interpretation of available hydrogeologic data suggests that some areas underlying eastern Indiana, north-central Kentucky, and western Ohio might be worthy of further study regarding the disposal of high-level radioactive waste in Precambrian crystalline rocks buried beneath Paleozoic sedimentary rocks in the area. The data indicate that (1) largest areas...
Potential hazards from future volcanic eruptions in California
C. Dan Miller
1989, Bulletin 1847
More than 500 volcanic vents have been identified in the State of California. At least 76 of these vents have erupted, some repeatedly, during the last 10,000 years. Past volcanic activity has ranged in scale and type from small rhyolitic and basaltic eruptions through large catastrophic rhyolitic eruptions. Sooner or...
Preliminary analysis of the shallow ground-water system in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana
Lee R. Watson, R. J. Shedlock, K. J. Banaszak, L. D. Arihood, P. K. Doss
1989, Open-File Report 88-492
The shallow groundwater system in the vicinity of the Grand Calumet River-Indiana Harbor Canal, Indiana was analyzed from June 1985 to May 1986. This analysis was done to obtain detailed information about the physical characteristics of the Calumet aquifer and the shallow groundwater flow system. 36 shallow wells were installed...
Tectonically controlled fan delta and submarine fan sedimentation of late Miocene age, southern Temblor Range, California
Robert T. Ryder, Alan Thomson
1989, Professional Paper 1442
The Santa Margarita Formation in the southern Temblor Range, composed of conglomerate and subordinate sandstone, evolved as a large complex of fan deltas and submarine fans in late Miocene time. An 80 to 90-m.y.-old granitic basement of the Salinian block and an accompanying 23.5-m.y.-old volcanic field now located in the...
