Fluoride, Nitrate, and Dissolved-Solids Concentrations in Ground Waters of Washington
W. E. Lum II, Gary L. Turney
1984, Open-File Report 82-508
This study provides basic data on ground-water quality throughout the State. It is intended for uses in planning and management by agencies and individuals who have responsibility for or interest in, public health and welfare. It also provides a basis for directing future studies of ground-water quality toward areas where...
Performance of ice meter and weight assemblies
V.R. Schneider, J.C. Futrell
1984, Water-Resources Investigations Report 84-4035
The performance of three ice meters and weight assemblies used by the U.S. Geological Survey and Environment Canada were compared in a towing tank. Each meter was rated individually on a rod suspension and then rerated on a cable suspension, with the appropriate weight assembly. Vertical and veer cable angles...
Appraisal of data for ground-water quality in Nebraska
R. A. Engberg
1984, Water Supply Paper 2245
This report summarizes existing data for groundwater quality in Nebraska and indicates their adequacy as a data base. Analyses have been made of water from nearly 10,000 wells by 8 agencies. Those analyses that meet reliability criteria have been aggregated by geologic source of water into four principal aquifer groupings--Holocene-Pleistocene...
Hydrogeologic setting and the potentiometric surfaces of regional aquifers in the Hollandale Embayment, southeastern Minnesota, 1970-80
G. N. Delin, D. G. Woodward
1984, Water Supply Paper 2219
Sedimentary Paleozoic rocks in the Hollandale embayment in southeastern Minnesota are as thick as 2,000 ft. This sedimentary sequence, together with the Proterozoic Hinckley Sandstone and the Quaternary drift, is divided into six regional aquifers: undifferentiated drift, Upper Carbonate, St. Peter, Prairie du Chien-Jordan, Ironton-Galesville, and Mount Simon-Hinckley. Potentiometric-surface maps for...
Geology and hydrothermal alteration at the Madh adh Dhahab epithermal precious-metal deposit, Kingdom of Saudi Arabia
J. L. Doebrich, J.P. LeAnderson
1984, Open-File Report 84-640
Mahd adh Dhahab is a late Precambrian epithermal gold-silver-base metal deposit located in the west-central part of the Arabian Shield. North-trending quartz veins containing base and precious metals cut an east-striking, north-dipping homoclinal sequence of volcanic, volcaniclastic, and epiclastic rocks of intermediate to felsic composition. Ore was localized where the...
Preliminary assessment of climatic change during Late Wisconsin time, southern Great Basin and vicinity, Arizona, California, and Nevada
W. G. Spaulding, S.W. Robinson, Frederick L. Paillet
1984, Water-Resources Investigations Report 84-4328
Nine plant macrofossil assemblages from the Eleana Range-2 packrat (Neotoma sp.) midden span 6,500 radiocarbon years and record local vegetational changes in the southern Great Basin of Nevada during the last one-half of the Late Wisconsin glacial age. Climatic reconstructions were developed to account for these changes. During the late...
