Slope and aspect classifications of Lake Tahoe Basin, California and Nevada
L. A. Peltz, K. D. Cartier, J. LaRue Smith
1994, Open-File Report 94-105
A geographic information system was used to develop maps of slope and aspect data for the Lake Tahoe basin of California and Nevada. The maps were pro- duced at 1:100,000 scale by using digital-elevation data derived from 1:24,000-scale maps. The maps show slope (steepness) and aspect (compass-direction) data for the...

Iodine-129 in the Snake River Plain aquifer at and near the Idaho National Engineering Laboratory, Idaho, 1990-91
L. J. Mann, T.M. Beasley
1994, Water-Resources Investigations Report 94-4053
From 1953 to 1990, an estimated 0.56 to 1.18 curies of iodine-129 were contained in wastewater generated by the Idaho Chemical Processing Plant (ICPP) at the Idaho National Engineering Laboratory. The waste- water was discharged directly to the Snake River Plain aquifer through a deep disposal well prior to February...
Geohydrology and water quality of stratified-drift aquifers in the lower Connecticut River basin, southwestern New Hampshire
