Progress report on Black Mesa monitoring program, 1984
G. W. Hill
1985, Open-File Report 85-483
The N aquifer is an important source of water in the 5,400 square-mile Black Mesa area on the Navajo and Hopi Indian Reservations. The project is designed to monitor long-term effects on the ground-water resources of the mesa as a result of withdrawals from the aquifer by a strip-mining operation....
Occurrence of ground water and potential for seawater intrusion, Island County, Washington
M. A. Jones
1985, Water-Resources Investigations Report 85-4046
The data from a study of groundwater availability and quality in Island County, Washington, are presented. Increased groundwater withdrawals associated with the population increase in Island County have caused concern about groundwater availability and potential seawater intrusion. The most widely used aquifer lies near sea level. Locally, available data indicate...
Hydrology of Lake Carroll, Hillsborough County, Florida
S.E. Henderson, R.D. Hayes, Y.E. Stoker
1985, Water-Resources Investigations Report 83-4261
Lakeshore property around Lake Carroll has undergone extensive residential development since 1960. This development increased the lake shoreline, altered surface water flow to and from the lake, and may have affected lake-stage characteristics. Some areas of the lake were dredged to provide fill material for lakefront property. Water-balance analyses for...
Impact on the Columbia River of an outburst of Spirit Lake
W. G. Sikonia
1985, Water-Resources Investigations Report 85-4054
A one-dimensional sediment-transport computer model was used to study the effects of an outburst of Spirit Lake on the Columbia River. According to the model, flood sediment discharge to the Columbia from the Cowlitz would form a blockage to a height of 44 feet above the current streambed of the...
Management of ground water and evolving hydrogeologic studies in New Jersey : a heavily urbanized and industrialized state in the northeastern United States
P. Patrick Leahy
1985, Water-Resources Investigations Report 85-4277
New Jersey is the most densely populated and one of the most industrialized states in the United States. An abundance of freshwater and proximity to major northeastern metropolitan centers has facilitated this development. Pumpage of freshwater from all aquifers in the State in 1980 was 730 million gallons per day...
Stratigraphy and characteristic mollusks of the Pamunkey Group (Lower Tertiary) and the Old Church Formation of the Chesapeake Group— Virginia coastal plain
Lauck W. Ward
1985, Professional Paper 1346
Along the Pamunkey River and its tributaries can be found a very complete, well-preserved, Tertiary stratigraphic record that reflects the sea-level changes as well as the local tectonic history of the central Virginia Coastal Plain. Using this record, I have described the lower Tertiary units and proposed a sequential model...
Cost effectiveness of the stream-gaging program in Pennsylvania
H.N. Flippo, T.E. Behrendt
1985, Water-Resources Investigations Report 85-4077
This report documents a cost-effectiveness study of the stream-gaging program in Pennsylvania. Data uses and funding were identified for 223 continuous-record stream gages operated in 1983; four are planned for discontinuance at the close of water-year 1985; two are suggested for conversion, at the beginning of the 1985 water year,...
Precision and bias of selected analytes reported by the National Atmospheric Deposition Program and National Trends Network, 1983; and January 1980 through September 1984
L.J. Schroder, A.W. Bricker, T. C. Willoughby
1985, Water-Resources Investigations Report 85-4275
Blind-audit samples with known analyte concentrations have been prepared by the U.S. Geological Survey and distributed to the National Atmospheric Deposition Program 's Central Analytical Laboratory. The difference between the National Atmospheric Deposition Program and National Trends Network reported analyte concentrations and known analyte concentrations have been calculated, and the...
Distribution and transport of trace substances in the Schuylkill River basin from Berne to Philadelphia, Pennsylvania
John K. Stamer, Thomas H. Yorke, Gary L. Pederson
1985, Water Supply Paper 2256-A
During the period from October 1978 to March 1981, the U.S. Geological Survey assessed the river quality of the Schuylkill River basin in Pennsylvania from the headwaters to the Fairmount Dam at Philadelphia (river mile 8.4). The assessment focused on the distribution and transport of trace metals and organic substances...
