Geohydrology and water quality of Cenozoic and Mesozoic units in southeast Missouri
Thomas O. Mesko
1990, Hydrologic Atlas 719
The U.S. Geological Survey is conducting a regional water-resources investigation of the Gulf Coast Regional Aquifer System, which includes the Mississippi embayment aquifer system in the southeast lowlands of Missouri (Grubb, 1986). The regional study will describe and evaluate the significant aquifer systems of Tertiary and younger age in parts...
Ground Water Atlas of the United States: Segment 6, Alabama, Florida, Georgia, South Carolina
James A. Miller
1990, Hydrologic Atlas 730-G
The four States-Alabama, Florida, Georgia, and South Carolina-that comprise Segment 6 of this Atlas are located adjacent to the Atlantic Ocean or the Gulf of Mexico, or both. These States are drained by numerous rivers and streams, the largest being the Tombigbee, Alabama, Chattahoochee, Suwannee, St. Johns, Altamaha, and Savannah...
Effects of acidic precipitation on the water quality of streams in the Laurel Hill area, Somerset County, Pennsylvania, 1983-86
J. L. Barker, E. C. Witt III
1990, Water-Resources Investigations Report 89-4113
Five headwater streams in the Laurel Hill area in southwestern Pennsylvania were investigated from September 1983 through February 1986 to determine possible effects of acidic precipitation on water quality. Precipitation in the Laurel Hill area is among the most acidic in the Nation, with a mean volume-weighted pH of 4.06....
Geohydrologic characteristics and simulated response to pumping stresses in the Sparta aquifer in East-Central Arkansas
Daniel J. Fitzpatrick, John M. Kilpatrick, Harry McWreath
1990, Water-Resources Investigations Report 88-4201
A finite difference digital model of the Sparta aquifer system in Arkansas was developed to aid in assessing the geohydrologic characteristics of the aquifer as well as the impact of withdrawals on water-level declines in the aquifer. The model consists of two layers. The Cockfield aquifer, represented by layer 1,...
Flow characteristics of streams that drain the Fort Apache and San Carlos Indian reservations, east-central Arizona, 1930-86
Stanley Baldys, J.A. Bayles
1990, Water-Resources Investigations Report 90-4053
Streamflow characteristics of the Salt River and Gila River basins in the Fort Apache and San Carlos Indian Reservations, were studied in response to pending adjudication of water resources in those basins. Statistical summaries were compiled for 28 streamflow-gaging stations in and near the reservation. Mean annual streamflow for 1930-86...
Hydrology, aquatic macrophytes, and water quality of Black Earth Creek and its tributaries, Dane County, Wisconsin, 1985-86
S. J. Field, D.J. Graczyk
1990, Water-Resources Investigations Report 89-4089
An intensive data-collection program for the Black Earth Creek basin in southern Wisconsin was conducted from October 1984 through September 1986 to assess the hydrology, aquatic macrophytes, and water quality in Black Earth Creek by the U.S. Geological Survey, in cooperation with the Wisconsin Department of Natural Resources. Three sites...
Water type and concentration of dissolved solids, chloride, and sulfate in water from the St. Francois aquifer in Missouri, Arkansas, Kansas, and Oklahoma
Jeffrey L. Imes, Jerri V. Davis
1990, Hydrologic Atlas 711-J
The St. Francois aquifer, the lowermost of three regional aquifers that form part of the Ozark Plateaus aquifer system, is composed of water-bearing sandstone and dolostone of Late Cambrian age. The aquifer was studied as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA, Jorgensen and Signor, 1981), a study...
