Digital-transport model study of Diisopropylmethylphosphonate (DIMP) ground-water contamination at the Rocky Mountain Arsenal, Colorado
James W. Warner
1979, Open-File Report 79-676
Diisopropylmethylphosphonate (DIMP) is an organic compound produced as a byproduct of the manufacture and detoxification of GB nerve gas. Ground-water contamination by DIMP from the disposal of wastes into unlined surface ponds at the Rocky Mountain Arsenal occurred from 1952 to 1956. A digital-transport model was used to determine the...
Ancient mines of the Farah Garan area, southwestern Saudi Arabia
C. W. Smith, H. Richard Blank
1979, Open-File Report 79-1659
Ancient miners, in quest of oxidized copper minerals, gold, silver, and possibly zinc, mined gossans to approximately 20 m depth in an area 1.1 by 0.5 km in extent at Farah Garan. The gossans, derived from sulfides, are ordinarily found at contacts between marble lenses and metavolcanic-metasedimentary rocks, but in...
Reconnaissance snow surveys of the National Petroleum Reserve in Alaska, April 1977 and April-May 1978
Charles E. Sloan, Dennis Trabant, William Glude
1979, Open-File Report 79-1342
Reconnaissance snow surveys of the NPRA (National Petroleum Reserve in Alaska) were made in April 1977 and April-May 1978 to ascertain general snow characteristics and distribution patterns. Thirty-nine sites in 1977 and forty-one sites in 1978 were sampled to determine snow depth, density, structure, and snow-soil interface temperature. In addition,...
Determination of arsenic in geologic materials using silver diethyldithiocarbamate
Eric P. Welsch
1979, Open-File Report 79-1442
A colorimetric method is herein described for the determination of arsenic in a wide variety of geologic materials. The method has a detection limit of 1 ppm and no serious interferences. As many as 50 samples can be analyzed per man per day using relatively simple apparatus....
Regional flood-frequency relations for west-central Florida
M.A. Seijo, R.F. Giovannelli, J. F. Turner
1979, Open-File Report 79-1293
This report presents regional relations for estimating the magnitude and frequency of floods on streams in west-central Florida. Flood prediction equations derived cover 20, 5-, 25-, 100-, 200-, and 500-year recurrence intervals. Annual floods for three geographic areas of west-central Florida were found to relate significantly to basin characteristics. Basin...
An economic analysis of selected strategies for dissolved oxygen management: Chattahoochee River, Georgia
John E. Schefter, Robert M. Hirsch
1979, Open-File Report 79-412
Using the Chattahoochee River as an example, a method for evaluating the cost-effectiveness of alternative strategies for dissolved oxygen (DO) management is demonstrated. The conceptual framework for the analysis is suggested by the economic theory of production. The minimum flow of the River and the percentage of the total waste...
Hydrogeologic data from the northern Powder River Basin, southeastern Montana
