Potentiometric surface of the intermediate aquifer system, west-central Florida, May 1987
B. R. Lewelling
1988, Open-File Report 87-705
The intermediate aquifer system within the Southwest Florida Water Management District underlies a 5,000 sq mi area of De Soto, Sarasota, Hardee, Manatee, and parts of Charlotte, Hillsborough, Highlands, and Polk Counties. The intermediate aquifer system occurs between the overlying surficial aquifer system and the underlying Floridan aquifer system, and...
Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, spring 1988
R.K. Gabrysch, C.E. Ranzau Jr., L.S. Coplin
1988, Open-File Report 88-334
Two maps show water levels in wells in the Houston, Texas, area in the Chicot aquifer and the Evangeline aquifer, spring 1988. Both the Chicot and the Evangeline aquifers are composed of several sand layers with different potentiometric surfaces. These maps, however, show approximations of single potentiometric surfaces that represent...
Geohydrology and 1985 water withdrawals of the aquifer systems in southwest Florida, with emphasis on the intermediate aquifer system
A. D. Duerr, B. R. Lewelling, J.T. Trommer
1988, Water-Resources Investigations Report 87-4259
In southwest Florida, principal hydrogeologic units include the surficial aquifer system, the intermediate aquifer system, and the Floridan aquifer system. The Floridan aquifer system consists of the Upper and Lower Floridan aquifers separated by a middle confining unit. The intermediate aquifer system includes all water-bearing units and confining units between...
Determination of evaporation and seepage losses, Upper Lake Mary near Flagstaff, Arizona
J.W. Blee
1988, Water-Resources Investigations Report 87-4250
Two mass-transfer equations were developed to compute evaporation as a part of the evaporation were seepage-loss study for the Upper Lake Mary Reservoir near Flagstaff, Arizona, which has a capacity of 15,620 acre-feet and a surface area of 876 acres. The mass-transfer equations do not require an independent measure of...
International strategic minerals inventory summary report; titanium
R.R. Towner, J.M. Gray, L.M. Porter
1988, Circular 930-G
Ilmenite and rutile are currently the most important titanium-bearing minerals, although anatase may be important in the future. Both ilmenite and rutile occur in hard-rock and placer deposits, but at present all rutile production and about half of the ilmenite production are from placer deposits. Anatase occurs in laterite deposits...
Well construction, lithology, and geophysical logs for boreholes in Bear Creek Valley near Oak Ridge, Tennessee
Z. C. Bailey, D. W. Hanchar
1988, Water-Resources Investigations Report 88-4068
Twenty-four wells were constructed at nine sites at Bear Creek Valley to provide geologic and hydrologic information. Lithologic samples and suits of geophysical logs were obtained from the deepest boreholes at six of the sites. Two of these boreholes at the base of Chestnut Ridge were completed in the Maynardville...
Ground-water resources and simulation of flow in aquifers containing freshwater and seawater, Island County, Washington
D. B. Sapik, Gilbert C. Bortleson, B. W. Drost, M. A. Jones, E. A. Prych
1988, Water-Resources Investigations Report 87-4182
Aquifers in Island County, Washington, that are intruded by seawater from Puget Sound contain chloride concentrations that exceed 100 mg/L. Chloride concentrations exceeded 100 mg/L in 24 % of the wells that were drilled below sea level and sampled in August 1981, but most of the chloride concentrations did not...
