Evaluation of the Mission, Santee, and Tijuana hydrologic subareas for reclaimed-water use, San Diego County, California
J. A. Izbicki
1985, Water-Resources Investigations Report 85-4032
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of treated municipal wastewater (reclaimed water). Groundwater quality has been impacted by agricultural water use, changes in natural recharge patterns, seawater intrusion, and groundwater movement from surrounding marine sediments. Groundwater...
Documentation of a numerical code for the simulation of variable density ground-water flow in three dimensions
L.K. Kuiper
1985, Water-Resources Investigations Report 84-4302
A numerical code is documented for the simulation of variable density time dependent groundwater flow in three dimensions. The groundwater density, although variable with distance, is assumed to be constant in time. The Integrated Finite Difference grid elements in the code follow the geologic strata in the modeled area. If...

Hydrogeology of the southwestern part of the Town of Hempstead, Nassau County, New York
R.K. Krulikas
1985, Water-Resources Investigations Report 85-4288
The groundwater resources of the southwestern part of the Town of Hempstead in Nassau County, NY were investigated in 1984. The area studied encompasses 85 sq mi, or 68% of the town 's 125-sq mi area. The groundwater reservoir underlying the area consists of unconsolidated gravel, sand, silt, and clay...
Hydrology, water quality, and ground-water-development alternatives in the Chipuxet ground-water reservoir, Rhode Island
H.E. Johnston, D.C. Dickerman
1985, Water-Resources Investigations Report 84-4254
A glacial sand and gravel aquifer in the Chipuxet River basin of Rhode Island forms a ground-water reservoir that could yield as much as 8.6 million gallons per day to wells; however, some streams would go dry for extended periods of time. The State Water Resources Board has tested five...

Habitat Suitability Index Models: Eastern brown pelican
Terrence M. Hingtgen, Rosemarie Mulholland, Alexander V. Zale
1985, FWS/OBS 82/10.90
A review and synthesis of existing information were used to develop a habitat model for the eastern brown pelican (Pelecanus occidentalis carolinensis). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1.0 (optimal habitat) for coastal areas within the eastern brown pelican's breeding...

Ground-water resources and potential hydrologic effects of surface coal mining in the northern Powder River basin, southeastern Montana
Steven E. Slagle, Barney D. Lewis, Roger W. Lee
1985, Water Supply Paper 2239
The shallow ground-water system in the northern Powder River Basin consists of Upper Cretaceous to Holocene aquifers overlying the Bearpaw Shale--namely, the Fox Hills Sandstone; Hell Creek, Fort Union, and Wasatch Formations; terrace deposits; and alluvium. Ground-water flow above the Bearpaw Shale can be divided into two general flow patterns....
Geology and geochronology of granitoid and metamorphic rocks of late Archean age in northwestern Wisconsin
P.K. Sims, Z. E. Peterman, R. E. Zartman, F. C. Benedict
1985, Professional Paper 1292-C
Granitoid rocks of the Puritan Quartz Monzonite and associated biotite gneiss and amphibolite in northwestern Wisconsin compose the southwestern part of the Puritan batholith of Late Archean age. They differ from rocks in the Michigan segment of the batholith in having been deformed by brittle-ductile deformation and partly recrystallized during...
Comparison of two methods for estimating ground-water recharge in 1978-80, Santa Maria Valley, California
Paul Lipinski
1985, Water-Resources Investigations Report 85-4129
Infiltration from the Santa Maria River and the lower part of the Sisquoc River constitutes most of the groundwater recharge to the aquifer system of Santa Maria Valley, California. The annual recharge volumes commonly are much greater or smaller than the long-term average annual recharge. A comparison of two methods...
Preliminary assessment of ground-water resources of Lauderdale County, Tennessee
W. S. Parks, J. K. Carmichael, D. D. Graham
1985, Water-Resources Investigations Report 84-4104
The ground-water resource in Lauderdale County is in a rudimentary stage of development. The principal shallow aquifers are the Mississippi alluvial deposits of Quaternary age and the Cockfield Formation, Memphis Sand, and Fort Pillow Sand of Tertiary age. Water levels fluctuate seasonally. High water levels generally occur in the winter,...

Mineral potential of felsic plutonic rocks in the north-central Arabian Shield, Kingdom of Saudi Arabia
W. J. Moore
1985, Open-File Report 85-6
Fourteen plutons of Late Proterozoie age potentially favorable for rare-element mineralization have been identified in a geochemical and petrographic assessment of felsic plutonic rocks in the north-central Arabian Shield (lat 23°00'-25°00' N., long 40°00'-45°00' E.). The plutons are highly fractionated, leucocratic granitoids assigned to a major magmatic pulse that spanned...

1985, Water-Resources Investigations Report 85-4056
The city of Battle Creek has 30 wells in the Verona well field capable of yielding 300 to 1,000 gallons per minute each. During summer, total withdrawals are as little as 6,000 gallons per minute. In early 1984, only 9 to 12 of the wells were being used; the remaining...
