Determination of selected anions in water by ion chromatography
Marvin J. Fishman, Grace Pyen
1979, Water-Resources Investigations Report 79-101
Ion chromatography is a rapid, sensitive, precise, and accurate method for the determination of major anions in rain water and surface waters. Simultaneous analyses of a single sample for bromide, chloride, fluoride, nitrate, nitrite, orthophosphate, and sulfate require approximately 20 minutes to obtain a chromatogram.Minimum detection limits range from 0.01...

M. E. Cooley, W. J. Head
1979, Water-Resources Investigations Report 79-6
The alluvial aquifer along the Greybull River in Wyoming, consists principally of the Greybull terrace doposits and flood-plain alluvium but also includes Burlington terrace deposits east of Burlington, the McKinnie terrace, and the younger, generally undissected alluvial-fan deposits. Well-log data and 18 surface-resistivity measurements at four localities indicate that the...
Documentation of a finite-element two-layer model for simulation of ground-water flow
Michael J. Mallory
1979, Water-Resources Investigations Report 79-18
This report documents a finite-element model for simulation of ground-water flow in a two-aquifer system where the two aquifers are coupled by a leakage term that represents flow through a confining layer separating the two aquifers. The model was developed by Timothy J. Durbin (U.S. Geological Survey) for use in...
Saltwater-barrier line in Florida: Concepts, considerations, and site examples
Jerry L. Hughes
1979, Water-Resources Investigations Report 79-75
Construction of canals and enlargement of streams in Florida has been mostly to alleviate impact of floods and to drain wetlands for development. Land drainage and heavy pumpage from coastal water-table aquifers has degraded potable ground and surface water with saltwater. Control of saltwater intrusion is possible through implementation of...

Jerry A. Leenheer, Edward W. D. Huffman Jr.
1979, Water-Resources Investigations Report 79-4
A standard procedure for analytical-scale dissolved organic carbon fractionation is presented, whereby dissolved organic carbon in water is first fractionated by a nonionic macroreticular resin into acid, base, and neutral hydrophobic organic solute fractions, and next fractionated by ion-exchange resins into acid, base, and neutral hydrophilic solute fractions. The hydrophobic...

1979, Water-Resources Investigations Report 79-46
Hydrology-related problems associated with North Carolina's major estuaries and sounds include contamination of some estuaries with municipal and industrial wastes and drainage from adjacent intensively-farmed areas, and nuisance-level algal blooms. In addition, there is excessive shoaling in some navigation channels, saltwater intrusion into usually fresh estuarine reaches, too-high or too-low...
Quantity and quality of urban runoff from three localities in the Denver Metropolitan area, Colorado
Sherman R. Ellis, William M. Alley
1979, Water-Resources Investigations Report 79-64
Considerable variation in constituent concentrations was shown in urban runoff data for 1975-77 from three metropolitan Denver drainage basins. Constituent concentrations, greatest during initial rainfall runoff, generally peaked midday of snowmelt runoff, corresponding with maximum melting and runoff. Instantaneous loads of constituents were largely a function of discharge. Days since...
