Development of a model to predict the adsorption of lead from solution on a natural streambed sediment
David Wayne Brown, John David Hem
1984, Water Supply Paper 2187
Adsorption of solutes by solid mineral surfaces commonly influences the dissolved ionic composition of natural waters. A model based on electrical double-layer theory has been developed which appears to be capable of characterizing the surface chemical behavior of a natural fine-grained sediment containing mostly quartz and feldspar. This variable surface...
Water resources data, Alabama water year 1983
H.C. Rollins, F.C. Sedberry, E.G. Ming, J.W. Tucker
1984, Water Data Report AL-83-1
Water resources data for the 1983 water year consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records for water discharge at 84 gaging stations; stage only at 23...
Hydrogeologic setting east of a low-level radioactive-waste disposal site near Sheffield, Illinois
J.B. Foster, George Garklavs, G.W. Mackey
1984, Water-Resources Investigations Report 84-4183
Core samples from 45 test wells and 4 borings were used to describe the glacial geology of the area east of the low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois. Previous work has shown that shallow ground water beneath the disposal site flows east through a pebbly-sand unit of...
Sediment Transport in the Lower Yampa River, Northwestern Colorado
John G. Elliott, James E. Kircher, Paul Von Guerard
1984, Water-Resources Investigations Report 84-4141
Discharge measurements and sediment samples were taken at streamflow-gaging station 09260050 Yampa River at Deerlodge Park in 1982 and 1983 to determine the annual sediment supply to the Yampa Canyon in Dinosaur National Monument. Forty-three years of discharge records at two tributary sites were combined to determine the historic discharge...
Preliminary study of the aquifers of the lower Mesilla Valley in Texas and New Mexico by model simulation
J. S. Gates, D. E. White, E. R. Leggat
1984, Water-Resources Investigations Report 84-4317
The aquifers in the lower Mesilla Valley of Texas and New Mexico provide water for irrigation, industrial use, and municipal supply. At present (1984), the shallow aquifer is used principally for irrigation. The medium-depth aquifer (the top of which is about 160 to 260 feet below land surface) and deep...
Quality of water, Quillayute River basin, Washington
M. O. Fretwell
1984, Water-Resources Investigations Report 83-4162
Groundwater in Quillayute River basin is generally of the calcium bicarbonate type, although water from some wells is affected by seawater intrusion and is predominantly of the sodium chloride type. The water is generally of excellent quality for most uses. River-water quality was generally excellent, as evaluated against Washington State...
Quality of ground water in agricultural areas of the San Luis Valley, south-central Colorado
Patrick Edelmann, David R. Buckles
1984, Water-Resources Investigations Report 83-4281
The quality of ground water in the principal agricultural areas of the San Luis Valley, south-central Colorado was evaluated using chemical analyses of water collected from 57 wells completed in the unconfined aquifer and from 25 wells completed in the confined aquifer. Ground water in both aquifers generally contains dissolved-solids...
Effects of irrigating with wastewater on ground-water quality at Fort Carson Military Reservation golf course near Colorado Springs, Colorado
Patrick Edelmann
1984, Water-Resources Investigations Report 83-4268
Fort Carson Military Reservation has used treatment wastewater for irrigation of the Fort Carson golf course since 1971. The effect of applied wastewater on groundwater quality at Fort Carson golf course was evaluated using water levels and water-quality data from 20 observation wells. The water-quality constituents analyzed included dissolved solids,...
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...
Evaluation of a hydrograph-shifting method for estimating suspended-sediment loads in Illinois streams
L.R. Frost, L.J. Mansue
1984, Water-Resources Investigations Report 84-4037
A hydrograph-shifting method for estimating monthly and annual suspended-sediment loads was applied to suspended-sediment records for 12 streams in Illinois. Transport equations for each station were developed and synthetic sediment-discharge hydrographs were then generated by using these transport equations and records of daily streamflow. Hydrographs were shifted to measured values...
