Effect of urban stormwater runoff on ground water beneath recharge basins on Long Island, New York
H. F. Ku, D. L. Simmons
1986, Water-Resources Investigations Report 85-4088
Urban stormwater runoff was monitored during 1980-82 to investigate the source, type, quantity, and fate of contaminants routed to the more than 3,000 recharge basins on Long Island and to determine whether this runoff might be a significant source of contamination to the groundwater reservoir. Forty-six storms were monitored at...
Metallogenic map of volcanogenic massive-sulfide occurrences in New Mexico
J. M. Robertson, M.S. Fulp, M.D. Daggett
1986, Miscellaneous Field Studies Map 1853-A
New Mexico volcanogenic massive-sulfide occurrences, which typically contain pyrite and pyrrhotite accompanied by variable amounts of base-metal sulfides and precious metals, are found within mainly subaqueous, compositionally bimodal metavolcanic successions of Early to Middle Proterozoic age that are exposed primarily in the north-central part of the state. Host rocks include...
Machine-readable files developed for the High Plains Regional Aquifer-System analysis in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
C.F. Ferrigno
1986, Water-Resources Investigations Report 86-4063
Machine-readable files were developed for the High Plains Regional Aquifer-System Analysis project are stored on two magnetic tapes available from the U.S. Geological Survey. The first tape contains computer programs that were used to prepare, store, retrieve, organize, and preserve the areal interpretive data collected by the project staff. The...
Water Resources Research Grant Program project descriptions, fiscal year 1986
Branch of Research Grants and Contracts
1986, Open-File Report 86-548
Information is presented on the 43 projects funded by the United States Geological Survey 's Water Resources Grant Program in fiscal year 1986. The report gives the grant number; project title; performing organization; principal investigator(s); dates; and a project description which includes (1) identification of the water related problems and...
Hydrogeology and simulation of water flow in strata above the Bearpaw Shale and equivalents of eastern Montana and northeastern Wyoming
W. R. Hotchkiss, J. F. Levings
1986, Water-Resources Investigations Report 85-4281
The Powder River, Bull Mountains, and Williston basins of Montana and Wyoming were investigated to understand the geohydrology and subsurface water flow. Rocks were separated into: Fox Hills-lower Hell Creek aquifer (layer 1), upper Hell Creek confining layer (layer 2), Tullock aquifer (layer 3), Lebo confining layer (layer 4), and...
Quality of stormwater runoff in the Blue River basin, Missouri and Kansas, July-October 1981 and April-July 1982
D. W. Blevins
1986, Water-Resources Investigations Report 84-4226
Stormwater-runoff sampling was done at three mainstem stations on the Blue River, Missouri, and three stations on urban tributaries. Concentrations of lead, iron, manganese, zinc, and ammonia nitrogen consistently exceeded Missouri water-quality standards. Many constituents were significantly correlated with large concentrations of suspended sediment from the agricultural areas in the...
Water resources of Weston County, Wyoming
M.E. Lowry, W. J. Head, J.G. Rankl, J.F. Busby
1986, Water-Resources Investigations Report 84-4079
Surface water is scarce in Weston County, Wyoming. Groundwater has been developed from rocks ranging in age from Mississippian to Holocene. Adequate supplies for domestic or stock use can be developed from wells generally less than 1,000 ft deep, except in the area underlain by a thick sequence of predominantly...
Evaluation of sampling methods used to estimate irrigation pumpage in Chase, Dundy, and Perkins counties, Nebraska
F.J. Heimes, R. R. Luckey, D.M. Stephens
1986, Water-Resources Investigations Report 86-4092
Combining estimates of applied irrigation water, determined for selected sample sites, with information on irrigated acreage provides one alternative for developing areal estimates of groundwater pumpage for irrigation. The reliability of this approach was evaluated by comparing estimated pumpage with metered pumpage for two years for a three-county area in...
Water resources of Hughes County, South Dakota
L.J. Hamilton
1986, Water-Resources Investigations Report 84-4195
Three major glacial-drift aquifers consisting of outwash sand and gravel underlie Hughes County, 784 sq mi of plains incised by the outwash-filled valley of the Missouri River in central South Dakota. Glacial-drift aquifers are recharged by more than 9,000 acre-feet of water annually and store about 1 million acre-feet of...
Data on snow chemistry of the Cascade-Sierra Nevada Mountains
L.B. Laird, Howard E. Taylor, R.E. Lombard
1986, Open-File Report 86-61
Snow chemistry data were measured for solutes found in snow core samples collected from the Cascade-Sierra Nevada Mountains from late February to mid-March 1983. The data are part of a study to assess geographic variations in atmospheric deposition in Washington, Oregon, and California. The constituents and properties include pH and...
Reconnaissance of the ground-water, surface-water system in the Zekiah Swamp Run basin, Charles and Prince Georges Counties, Maryland
H. T. Hopkins, G. T. Fisher, L. J. McGreevy
1986, Water-Resources Investigations Report 86-4097
The water table in the alluvium of the Zekiah Swamp Run valley in southern Maryland is above stream level during most of the year and the alluvial aquifer contributes water to the stream. During the summer, however, high evapotranspiration sometimes lowers the water table below the stream level. Water then...
Water resources of Lake and Moody counties, South Dakota
D. S. Hansen
1986, Water-Resources Investigations Report 84-4209
The primary sources of surface water in Lake and Moody Counties are the Big Sioux River and its intermittent tributaries, and Lakes Herman, Madison, and Brant. Seasonal variations in streamflow and lake levels are directly related to seasonal variations in precipitation. Dissolved-solids concentration in water from streams and lakes increases...
Hydrologic conditions in the Klatt Bog area, Anchorage, Alaska
R. L. Glass
1986, Water-Resources Investigations Report 85-4330
Klatt Bog is a 2.3 sq mi wetland in Anchorage, Alaska which provides habitat for many wildlife species but also offers potential sites for residential, commercial, and agricultural developments. Precipitation, the main source of water for the area, averages 15 in/yr; during the 1983 study period, precipitation was 12.16 inches....
The SALT NORM : a quantitative chemical-mineralogical characterization of natural waters
Marc W. Bodine Jr., Blair F. Jones
1986, Water-Resources Investigations Report 86-4086
The new computer program SNORM calculates the salt norm from the chemical composition of a natural water. The salt norm is the quantitative ideal equilibrium assemblage that would crystallize if the water evaporated to dryness at 25 C and 1 bar pressure under atmospheric partial pressure of CO2. SNORM proportions...
