Water-quality study of Tulpehocken Creek, Berks County, Pennsylvania, prior to impoundment of Blue Marsh Lake
James L. Barker
1977, Water-Resources Investigations Report 77-55
Blue Marsh Lake is planned as a multipurpose impoundment to be constructed on Tulpehocken Creek near Bernville, Berks County, Pennsylvania. Prior to construction, samples of water, bed material, and soil were collected throughout the impoundment site to determine concentrations of nutrients, insecticides, trace metals, suspended sediment, and bacteria. Analyses of water...
Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, September 1976
Paul D. Ryder, L. R. Mills
1977, Open-File Report 77-551
The water table in the surficial aquifer and the potentiometric surface of the Florida aquifer in a 1200 square-mile area in west-central Florida are mapped semiannually by the U. S. Geological Survey. Maps are prepared on the basis of water levels measured in wells each May to coincide with seasonal...
Shelled benthic fauna of the eastern Chukchi Sea
Dennis M. Mann
1977, Open-File Report 77-672
The purposes of this study were to identify the benthic shelled infauna and epifauna of the eastern Chukchi Sea, compile species lists and distribution maps, determine recurrent groups of species (communities), and examine the environmental parameters that may control the distribution of the faunal groups. The study was partly supported...
Ground-water appraisal of the Pineland Sands area, central Minnesota
J. O. Helgesen
1977, Water-Resources Investigations Report 77-102
The Pineland Sands area consists of 770 square miles of surficial glacial outwash, which is undergoing increasing ground-water development for irrigation. The aquifer material is commonly very fine sand to fine gravel, and grain size generally increases from south to north. Thickness, transmissivity, and theoretical well yields are highest in...
Water resources data for California; water year 1975; Volume 2: Pacific Slope basins from Arroyo Grande to Oregon State line except Central Valley
Water Resources Division, U.S. Geological Survey
1977, Water Data Report CA-75-2
Water-resources data for the 1975 water year for California consist of records of streamflow and contents of reservoirs at gaging stations, partial-record stations, and miscellaneous sites; records of water quality including the physical, chemical, and biological characteristics of surface and ground water; and records of water levels in selected observation...
Geology and ground water in Door County, Wisconsin, with emphasis on contamination potential in the Silurian dolomite
Marvin G. Sherrill
1977, Open-File Report 77-61
Door County, a recreational and fruit-growing area bordering Lake Michigan in northeastern Wisconsin, has had a long history of ground-water contamination from surface and near-surface sources. Contamination is most severe in late summer when fruit-canning operations and the influx of tourists create additional wastes. Silurian dolomite is the upper bedrock...
