Chemical interactions of aluminum with aqueous silica at 25 degrees Celsius
John David Hem, C. E. Roberson, Carol J. Lind, W.L. Polxer
1973, Water Supply Paper 1827-E
Solutions containing from 10 -5 to 10 -2 moles per liter of aluminum and dissolved silica in various ratios were aged at pH levels between 4 and 10 at 25?C. A colloidal amorphous product having the composition of halloysite was produced in most solutions. It had a consistent and reversible...
Water resources of the New Jersey part of the Ramapo River basin
John Vecchioli, E.G. Miller
1973, Water Supply Paper 1974
The Ramapo River, a major stream in the Passaic River basin, drains an area of 161 square miles, 70 percent of which is in Orange and Rockland Counties, N.Y., and 30 percent is in Bergen and Passaic Counties, N.J. This report describes the hydrology of the New Jersey part of...
Appraisal of ground water for irrigation in the Little Falls area, Morrison County, Minnesota
John O. Helgesen
1973, Water Supply Paper 2009-D
Anticipated irrigation on sandy soils has prompted evaluation of ground-water supply potential in the Little Falls area. Geologic conditions cause ground-water availability to vary widely in the area. The largest and most readily available groundwater source is the glacial outwash sand and gravel from which the soils were derived. Test augering...
Cost analysis of ground-water supplies in the North Atlantic region, 1970
Dagfin John Cederstrom
1973, Water Supply Paper 2034
The cost of municipal and industrial ground water (or, more specifically, large supplies of ground water) at the wellhead in the North Atlantic Region in 1970 generally ranged from 1.5 to 5 cents per thousand gallons. Water from crystalline rocks and shale is relatively expensive. Water from sandstone is less...
Use of finite-difference arrays of observation wells to estimate evapotranspiration from ground water in the Arkansas River Valley, Colorado
Edwin P. Weeks, M.L. Sorey
1973, Water Supply Paper 2029-C
A method to determine evapotranspiration from ground water was tested at four sites in the flood plain of the Arkansas River in Colorado. Approximate ground-water budgets were obtained by analyzing water-level data from observation wells installed in five-point arrays. The analyses were based on finite difference approximations of the differential...
Ground-water levels in the United States, 1967-71, north-central States
Water Resources Division, U.S. Geological Survey
1973, Water Supply Paper 2090
Publication of ground-water level data for the United States in watersupply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire Nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have...
Effects of coal mining on the water resources of the Tradewater River Basin, Kentucky
Hayes F. Grubb, Paul D. Ryder
1973, Water Supply Paper 1940
The effects of coal-mine drainage on the water resources of the Tradewater River basin, in the Western Coal Field region of Kentucky, were evaluated (1) by synthesis and interpretation of 16 years of daily conductance data. 465 chemical analyses covering an 18-year period, 28 years of daily discharge data, and...
