Trace-element distribution around a South Texas roll-type uranium deposit
Charles S. Spirakis
1979, Open-File Report 79-1375
The distribution of trace elements around a south Texas roll-type uranium deposit was examined using semiquantitative emission spectroscopic analytical data complemented by some quantitative data. The results suggest that of the 50 elements analyzed, only beryllium and possibly vanadium are enriched in the altered rock on the updip side of...
Preliminary report on the geology and geophysics of drill hole UE25a-1, Yucca Mountain, Nevada Test Site
Richard W. Spengler, D. C. Muller, R.B. Livermore
1979, Open-File Report 79-1244
A subsurface geologic study in connection with the Nevada Nuclear Waste Storage Investigations has furnished detailed stratigraphic and structural information about tuffs underlying northeastern Yucca Mountain on the Nevada Test Site. Drill hole UE25a-1 penetrated thick sequences of nonwelded to densely welded ash-flow and bedded tuffs of Tertiary age. Stratigraphic...
Evaluation of a digital model for estuarine water quality simulation in waste allocation studies
G.E. Seaburn, Marshall E. Jennings, Michael L. Merritt
1979, Water-Resources Investigations Report 78-54
Hydrologic and water-quality data were collected on 4 estuaries in Pasco, Citrus, and Pinellas Counties, Florida, to evaluate modeling results. Current and predicted waste loading of the four estuaries was simulated by use of a two-dimensional steady-state, intertidal-condition model. Concentrations of DO, carbonaceous and nitrogenous BOD, and chloride were simulated...
Revision of the documentation for a model for calculating effects of liquid waste disposal in deep saline aquifers
Inc. INTERA Environmental Consultants
1979, Water-Resources Investigations Report 79-96
The model developed under this contract is a modified version of the deep well disposal model developed by INTERCOMP Resource Development and Engineering, Inc., for the U.S. Geological Survey (A model for calculating effects of liquid waste disposal in deep saline aquifers). The model is a finite-difference numerical solution of...
Water-resources investigations of the U.S. Geological Survey in Montana, October 1978 through September 1979
Water Resources Division, U.S. Geological Survey
1979, Open-File Report 79-418
The report describes water-resources investigations of the U.S. Geological Survey in Montana, October 1978 through September 1979. Programs consist of (1) collecting hydrologic data on a continuing basis, (2) conducting water-resources appraisals of surface and ground water, (3) conducting supportive research in hydrology and related fields, (4) disseminating water data...
