Effects of artificial recharge on the Ogallala aquifer, Texas
Richmond Flint Brown, W.S. Keys
1985, Water Supply Paper 2251
Four recharge tests were conducted by injecting water from playa lakes through wells into the Ogallala Formation. Injection was by gravity flow and by pumping under pressure. At one site, 34-acre feet of water was injected by gravity and produced a significant increase in yield of the well. At a...
Geohydrology and model analysis of stream-aquifer system along the Arkansas River in Kearny and Finney Counties, southwestern Kansas
L. E. Dunlap, Richard J. Lindgren, C. G. Sauer
1985, Water Supply Paper 2253
A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions in an area comprising nearly 850,000 acres along the Arkansas River valley in Kearny and Finney Counties, southwestern Kansas. The Arkansas River meanders atop and interacts hydraulically with the...
Determination of diffusivities in the Rustler Formation from exploratory-shaft construction at the Waste Isolation Pilot Plant in southeastern New Mexico
Ken Stevens, Walt Beyeler
1985, Water-Resources Investigations Report 85-4020
The construction of an exploratory shaft 12 feet in diameter into the Salado Formation (repository horizon for transuranic waste material) at the Waste Isolation Pilot Plant site in southeastern New Mexico affected water-levels in water-bearing zones above the repository horizon. By reading the construction history of the exploratory shaft, an...
Distribution of polychlorinated biphenyls in the Housatonic River and adjacent aquifer, Massachusetts
Frederick B. Gay, Michael H. Frimpter
1985, Water Supply Paper 2266
Polychlorinated biphenyls (PCB's) are sorbed to the fine-grained stream-bottom sediments along the Housatonic River from Pittsfield, Massachusetts, southward to the Massachusetts-Connecticut boundary. The highest PCB concentrations, up to 140,000 micrograms per kilogram, were found in samples of bottom material from a reach of the river between Pittsfield and Woods Pond...
Description and preliminary testing of the CDSN Seismic Sensor Systems
Jon Peterson, Edwin E. Tilgner
1985, Open-File Report 85-288
The China Digital Seismograph Network (CDSN) is being designed and installed to provide the People's Republic of China with the facilities needed to create a national digital database for earthquake research. The CDSN, which is being developed jointly by the PRC State Seismological Bureau and the U.S. Geological Survey, will...
Quality of storm-water runoff, Mililani Town, Oahu, Hawaii, 1980-84
Cheryl M. Yamane, Marty G. Lum
1985, Water-Resources Investigations Report 85-4265
Storm water runoff and rainfall data were collected at two urban sites in Mililani Town, Oahu, Hawaii between September 1980 and August 1984. The data included results from analyses of 300 samples of storm water runoff. Turbidity, suspended solids, Kjeldahl nitrogen, and phosphorus concentrations exceeded the State of Hawaii Department...
Hydrologic data in small watersheds, coal-mining region, west-central Indiana, October 1980 to June 1983, and instrumentation and methods of collecting the data
D.E. Renn, R.F. Duwelius, C.R. Keeton, J.W. Tyler Jr.
1985, Open-File Report 85-402
Hydrologic data were collected in seven watersheds ranging in area from 0.11 to 4.87 square miles. Principal uses of land include farming in two of the watersheds, farming and forestry in one, farming and unreclaimed surface coal mines in one, reclaimed surface coal mines in two, and an unreclaimed surface...
