Research by the U.S. Geological Survey on organic materials in water
Robert Andrew Baker
1976, Circular 744
The U.S. Geological Survey has responsibility for investigating the Nation's water resources for source, availability, quantity, and quality. This paper describes the Geological Survey's research on organic substances in water and fluvial sediments. Results and ongoing studies are examined. Typical research includes: Separation, concentration, and chromatographic identification of volatile acids;...
Earthquakes and related catastrophic events, Island of Hawaii, November 29, 1975: A preliminary report
Robert I. Tilling, R. Y. Koyanagi, P. W. Lipman, J. P. Lockwood, J.G. Moore, D. A. Swanson
1976, Circular 740
The largest earthquake in over a century--magnitude 7.2 on the Richter Scale--struck Hawaii the morning of November 29, 1975, at 0448. It was centered about 5 km beneath the Kalapana area on the southeastern coast of the island at 19° 20.1 ' N., long 155° 01.4 ' W.). The earthquake...
Ground-water resources in the Lompoc area, Santa Barbara County, California
G.A. Miller
1976, Open-File Report 76-183
Water supplies in the Lompoc plain are pumped from highly permeable gravel and sand, which make up the main water-bearing zone. The history of ground-water quality in the Lompoc area shows little change in the Lompoc upland and the Lompoc terrace, but an increase in the concentration of dissolved solids...
Selection of streamflow and reservoir-release models for river-quality assessment
Marshall E. Jennings, James O. Shearman, Daniel P. Bauer
1976, Circular 715-E
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Analytical precision of one-sixth order semiquantitative spectrographic analysis
J. M. Motooka, D. J. Grimes
1976, Circular 738
Over 2,700 separate analyses were made on 22 different geologic samples selected to cover wide concentration ranges for the 30 elements studied. The precision for low, medium, and high concentrations of each element determined is represented by superimposed frequency diagrams and displays the frequency of reported values occurring within one-sixth...
Water resources data for Hawaii and other Pacific areas, water year 1975
Water Resources Division, U.S. Geological Survey
1976, Water Data Report HI-75-1
Water resources data for the 1975 water year for Hawaii and other Pacific Areas consist of records of stage, discharge, and water quality of streams; stage of a reservoir; and water levels and water quality in wells and springs. This report contains discharge records for 164 gaging stations; stage only...
