Map showing how the potentiometric surface of the Magothy Aquifer of September 1979 differed from the potentiometric surface of September 1977 in southern Maryland
Frederick K. Mack, J. C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-632
This map is based on the differences between two sets of water-level measurements made in 63 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1979, a relatively wet year. The map shows that the potentiometric surface in 1979, in...

Data pertaining to wells in and near Burial Ground 4 (radioactive waste) at Oak Ridge National Laboratory, Tennessee is presented for the period 1975-1979. An inventory of wells, measurements of water levels, well hydrographs, and a map showing the location of the wells, are included. (USGS)...
Water quality of Alimagnet, Farquar, and Long Lakes in Apple Valley, Minnesota
M.R. Have, G. A. Payne, M. A. Ayers
1981, Water-Resources Investigations Report 81-40
Alimagnet, Farquar, and Long Lakes, in Apple Valley, Minnesota, were sampled from 1973-79 to determine their physical and chemical characteristics. A storm-sewer inlet to Alimagnet Lake was also sampled during two storms in 1978. The 1976-77 drought caused a more noticeable effect on the quality of the lakes than any...

Bedded Precambrian iron deposits of the Tobacco Root Mountains, southwestern Montana
H. L. James
1981, Professional Paper 1187
Bedded deposits of iron-formation are minor components of the thoroughly metamorphosed and deformed Precambrian rocks that make up the core of the Tobacco Root Mountains. The rocks are Archean in age; they predate a major Precambrian orogeny that affected all of southwestern Montana about 2,750 m.y. ago. The principal bed...
