Upper Cenozoic deposits of the central Delmarva Peninsula, Maryland and Delaware
James Patrick Owens, Charles Storrow Denny
1979, Professional Paper 1067-A
The surface and shallow subsurface sediments of the lower Delmarva Peninsula include beds ranging in age from Miocene to Holocene. The oldest beds appear to be typical shelf deposits of the Chesapeake Group (Calvert-Choptank age). These marine units are overlain by deltaic deposits, which range from fluviatile facies in the...
The Parsonsburg Sand in the central Delmarva Peninsula, Maryland and Delaware
Charles Storrow Denny, J. P. Owens, L.A. Sirkin, Meyer Rubin
1979, Professional Paper 1067-B
The Parsonsburg Sand, a surface sand largely of Wisconsin age, caps terraces east of some of the major streams and mantles broad areas on the uplands of the central Delmarva Peninsula, Maryland and Delaware. The main body of the formation east and south of Salisbury, Md., ranges from 1.25 to...
Hydrologic data for the southwest subsurface-injection test site, St. Petersburg, Florida
John J. Hickey, R. M. Spechler
1979, Open-File Report 78-852
Three injection wells, A1, A2, and A3, and nine observation wells, B1 through B9, were constructed at the Southwest St. Petersburg site to determine the feasibility of injecting wastewater treatment plant effluent into permeable zones containing saline water. Two withdrawal tests and one injection test were performed. Both withdrawal tests...
Saline-seep development in the Hailstone Basin, northern Stillwater County, Montana
Barney D. Lewis, Stephen G. Custer, Marvin R. Miller
1979, Water-Resources Investigations Report 79-107
As a result of an increase in saline seep occurrence in Montana, a study was begun in 1974 to determine the hydrogeology of saline seeps in the Hailstone basin. The aquifer is composed of colluvium of Holocene age. The impermeable Cretaceous Niobrara Formation underlies the saturated zone basinwide. The ground-water...
Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...
Reconnaissance geology of the Wadi Shuqub Quadrangle, sheet 20/41 A, Kingdom of Saudi Arabia
Robert C. Greene, Louis Gonzalez
1979, Open-File Report 79-1353
The Wadi Shuqub quadrangle (sheet 20/41 A) lies in the high mountainous part of the Hijaz plateau in west-central Saudi Arabia. The quadrangle is underlain chiefly by Precambrian layered metasedimentary and metavolcanic rocks that are intruded by plutons ranging in composition from gabbroic to granitic. The metasedimentary rocks include quartzite,...
Interim data report on the geohydrology of the proposed waste isolation pilot plant site, southeast New Mexico
Jerry W. Mercer, R.B. Orr
1979, Water-Resources Investigations Report 79-98
Data collected at the proposed Waste Isolation Pilot Plant site in southeast New Mexico through September 1977 help define hydrologic conditions at the contact between the Permian Rustler and Salado Formations, and Culebra and Magenta Dolomite Members of the Rustler Formation. Preliminary calculations of transmissivity along the Rustler-Salado contact range...
Effects of seepage from fly-ash settling ponds and construction dewatering on ground-water levels in the Cowles unit, Indiana Dunes National Lakeshore, Indiana
William R. Meyer, Patrick Tucci
1979, Water-Resources Investigations Report 78-138
Part of the Indiana Dunes National Lakeshore shares a common boundary with the Northern Indiana Public Service Company (NIPSCO). This area is underlain by unconsolidated deposits approximately 180 feet thick. NIPSCO accumulates fly ash from the burning of coal in electric-power generating units in settling ponds. Seepage from the ponds...
