Planning report for the Gulf Coast Regional Aquifer-System Analysis in the Gulf of Mexico coastal plain, United States
Hayes F. Grubb
1984, Water-Resources Investigations Report 84-4219
Large quantities of water for municipal, industrial and agriculture use are supplied from the aquifers in Tertiary and younger sediments over an area of about 225,000 square miles in the Coastal Plain of Alabama, Arkansas, Florida, Illinois, Kentucky, Louisiana, Mississippi, Missouri, Tennessee, and Texas. Three regional aquifer systems, the Mississippi...
The Georges Bank monitoring program 1983: Analysis of trace metals in bottom sediments
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, P. J. Aruscavage, A. F. Dorrzapf, R. G. Johnson, C.M. Parmenter, M. J. Pickering, D. C. Brewster, F. W. Brown
1984, Circular 915
From July 1981, when drilling began on Georges Bank, to May 1982, the concentration of barium, a major element in drilling mud, has increased by a factor of 3.5 in bulk sediments 200 m from the drill site in block 410 and by a factor of 2.3 at the drill...
Estimates of dissolved and suspended substance yield of stream basins in Michigan
T. R. Cummings
1984, Water-Resources Investigations Report 83-4288
Water-quality data collected at 20 stations in Michigan were used to develop regression equations relating loads of dissolved and suspended substances to discharge. These equations and mean daily discharge were used to estimate long-term loads, which then were converted to estimates of drainage basin yields. These yields were compared to...
Reconnaissance of the shallow-unconfined aquifer in Salt Lake Valley, Utah
R. L. Seiler, K.M. Waddell
1984, Water-Resources Investigations Report 83-4272
The shallow-unconfined aquifer in Salt Lake (Jordan) Valley, Utah, seldom is used for domestic or industrial purposes because it yields water slowly and is readily contaminated. The water in the aquifer, however, can flood basements and is a potential source of contamination to other water supplies. In about one-half of...
Cost-effectiveness of the stream-gaging program in New Jersey
R.D. Schopp, R.L. Ulery
1984, Water-Resources Investigations Report 84-4108
The results of a study of the cost-effectiveness of the stream-gaging program in New Jersey are documented. This study is part of a 5-year nationwide analysis undertaken by the U.S. Geological Survey to define and document the most cost-effective means of furnishing streamflow information. This report identifies the principal uses...
Earth and water resources and hazards in Central America
Charles G. Cunningham, R.W. Fary, Marianne Guffanti, Della Laura, M. P. Lee, C.D. Masters, R. L. Miller, Ferdinand Quinones-Marquez, R.W. Peebles, J.A. Reinemund, D. P. Russ
1984, Circular 925
Long-range economic development in Central America will depend in large part on production of indigenous mineral, energy, and water resources and on mitigation of the disastrous effects of geologic and hydrologic hazards such as landslides, earthquakes, volcanic eruptions, and floods. The region has six world-class metal mines at present as...
