Ground-water levels in the alluvial aquifer in eastern Arkansas, 1986
Maria Plafcan
1987, Open-File Report 87-545
This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service, and local Conservation Districts, contains groundwater level measurements of 512 wells tapping the Mississippi River Valley alluvial aquifer of eastern Arkansas. The measurements were made by district...

Hydrologic data from the integrated lake-watershed acidification study in the west-central Adirondack Mountains, New York : October 1977 through January 1982
N.E. Peters, Peter S. Murdoch, F.N. Dalton
1987, Open-File Report 85-80
Hydrologic data were collected from three forested headwater lake watersheds in Herkimer and Hamilton Counties from October 1977 through early January 1982 as part of the Integrated Lake-Watersheds Acidification Study (ILWAS). ILWAS was established in 1977 to determine why these lakes differ in pH when all receive equal amounts of...
Water movement in the unsaturated zone at a low-level radioactive-waste burial site near Barnwell, South Carolina
K.F. Dennehy, P.B. McMahon
1987, Open-File Report 87-46
Four unsaturated zone monitoring sites and a meteorologic station were installed at the low level radioactive waste burial site near Barnwell, South Carolina, to investigate the geohydrologic and climatologic factors affecting water movement in the unsaturated zone. The study site is located in the Atlantic Coastal Plain. The unsaturated zone...
Hydrogeologic data from a study of the freshwater zone/salinewater zone interface in the Edwards Aquifer, San Antonio region, Texas
Dianne Pavlicek, Ted A. Small, Paul L. Rettman
1987, Open-File Report 87-389
The highly productive freshwater zone of the Edwards aquifer in the San Antonio region (fig. 1) is the sole-source water supply for more than 1 million people. A transitional interface exists between the freshwater zone and the downdip, salinewater zone. A 1,000 mg/L (milligrams per liter) dissolved solids-concentration contour defines...
Chemical analyses of water samples from the Picher mining area, northeast Oklahoma and southeast Kansas
David L. Parkhurst
1987, Open-File Report 87-453
Chemical analyses are presented for 169 water samples from Tar Creek drainage and the Picher lead-zinc mining area of northeast Oklahoma and southeast Kansas. Water samples were taken from November 1983 through February 1986 from the abandoned mines, from points of mine-water discharge, and from surface-water locations upstream and downstream...
