Water in carbonate rocks of the Madison Group in southeastern Montana: A preliminary evaluation
W. Roger Miller
1976, Water Supply Paper 2043
The Madison Group of Mississippian age comprises, from oldest to youngest, the Lodgepole and Mission Canyon Limestones and the Charles Formation. The Madison crops out in the Bighorn and Pryor Mountains and in the mountains west of the study area. These rocks consist of cyclically deposited normal-marine carbonates and restricted-marine...

Hydrology and environmental aspects of Erie Canal (1817-99)
Walter Basil Langbein
1976, Water Supply Paper 2038
As the first major water project in the United States, the old Erie Canal provides an example of the hydrological and environmental consequences of water development. The available record shows that the project aroused environmental fears that the canal might be impaired by the adverse hydrologic effects of land development...

Analytical precision of one-sixth order semiquantitative spectrographic analysis
J. M. Motooka, D. J. Grimes
1976, Circular 738
Over 2,700 separate analyses were made on 22 different geologic samples selected to cover wide concentration ranges for the 30 elements studied. The precision for low, medium, and high concentrations of each element determined is represented by superimposed frequency diagrams and displays the frequency of reported values occurring within one-sixth...
Status of ground-water modeling in the U.S. Geological Survey
Charles A. Appel, J.D. Bredehoeft
1976, Circular 737
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of ground-water problems. Types of problems for which models have been, or are being, developed include: (1) ground-water flow in saturated or partially unsaturated materials, (2) land subsidence resulting from ground-water...

Phosphorite and other apatite-bearing sedimentary rocks in the Precambrian of northern Michigan
William F. Cannon, J. S. Klasner
1976, Circular 746
Phosphatic pebbles are widespread in basal units of the Marquette Range Supergroup (Precambrian X) in the central part of the Upper Peninsula of Michigan. At one locality, a conglomeratic bed about 15 m thick averages about 15 percent P2O5, and many thinner beds are of comparable grade. This occurrence is...
Guidelines for sample collecting and analytical methods used in the U.S. Geological Survey for determining chemical composition of coal
Vernon Emanuel Swanson, Claude Huffman
1976, Circular 735
This report is intended to meet the many requests for information on current U.S. Geological Survey procedures in handling coal samples. In general, the exact type and number of samples of coal and associated rock to be collected are left to the best judgment of the geologist. Samples should be of...
Geologic appraisal of the petroleum potential of offshore southern California; the borderland compared to onshore coastal basins
James Carlton Taylor
1976, Circular 730
Offshore southern California is part of a much larger Pacific continental margin, and the two areas have a similar geologic history at least as far back as middle Tertiary time. Assessment of the petroleum potential of the offshore Southern California borderland is accomplished by examining the adjacent highly explored productive...
Hydrologic evaluation of salinity control and reclamation projects in the Indus Plain, Pakistan--A summary
Maurice John Mundorff, P.H. Carrigan Jr., T.D. Steele, A. D. Randall
1976, Water Supply Paper 1608-Q
This report summarizes the observations and findings of a team of four specialists from the U.S. Geological Survey assigned to Pakistan under the auspices of the U.S. Agency for International Development during May to August 1972 for a hydrologic evaluation of Salinity Control and Reclamation Projects in the Indus Plain...
Artificial recharge through a well in fissured carbonate rock, west St. Paul, Minnesota
Harold O. Reeder, Warren W. Wood, G. G. Ehrlich, Ren Jen Sun
1976, Water Supply Paper 2004
The Prairie du Chien Group was injected with 2,754,000 gallons (368,200 cubic feet), or 10,430 cubic metres, of municipally treated water at about 100 gallons per minute (13.4 cubic feet per minute), or 6.3 litres per second, for 20 days. The injection-pipe system was designed to utilize pipe friction rather...
Land and natural resource information and some potential environmental effects of surface mining of coal in the Gillette area, Wyoming
William Richard Keefer, R. F. Hadley
1976, Circular 743
Campbell County, along the east margin of the Powder River Basin in northeastern Wyoming, contains more coal than any other county in the United States. The principal deposit is the Wyodak-Anderson coal bed. The bed is 50-100 feet (15-30 meters) thick over large areas, lies less than 200 feet (60...

For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
