A sensitive field test for heavy metals in water
Lyman C. Huff
1948, Economic Geology (43) 675-684
A semiquantitative colorimetric analytical method using dithizone to detect traces of heavy metals in natural water is described. Although reagents of exceptional purity are required, only simple equipment is needed and the test can be made in a few minutes in the field. A combined mixed color and mono color...
Geology and ground water of the Casablanca Basin, Chile
G. C. Taylor Jr.
1948, Economic Geology (73) 661-674
"In the uplands the Cretaceous granodiorite and granite contain water in the weathered zones, and in joints and fractures. These yield small supplies of good water to springs and to shallow domestic and stock wells. The alluvial fill of the lowlands contains a zone of saturation that is sustained by...
Ground water hydraulics as a geophysical aid
John G. Ferris
1948, Technical Report 1
The publication of the non-equilibrium formula in 1935 in a paper by Theis marked the opening of a new era in the analysis and understanding of the hydraulics of percolating ground waters. Through the past decade 9 an ever-increasing number of engineers and geologists have become familiar-with the application of...
Preliminary notes on distribution of uranium in the Florida pebble phosphate field and suggestions for studying and sampling
Water Resources Division, U.S. Geological Survey
1948, Trace Elements Memorandum 73
The accompanying map and sections show examples of the present state of information about the occurrence of the "Leached" uranium-bearing bed in the Florida pebble phosphate district. The dashed lines on the map define, as closely as present data permit, the limit of the area in which this bed...
The value of certain drugs, especially sulfa drugs, in the treatment of furunculosis in brook trout, Salvelinus fontinalis
J.S. Gutsell
1948, Transactions of the American Fisheries Society (75) 186-199
Furunculosis of salmonoid fishes is a dread epizootic disease caused by a general infection by Bacterium salmonicida.In this experiment, treatment was tried with sulfonamides and another drug, “furacin” or “2–20–99” (new drug). The four treatments first used were: (1) sulfamerazine, (2) sulfathiazole, and (3) furacin, each administered by...
Discharge and sediment loads in the Boise River drainage basin, Idaho 1939-40
S. K. Love, Paul Charles Benedict
1948, Water Supply Paper 1048
The Boise River project is a highly developed agricultural area comprising some 520 square miles of valley and bench lands in southwestern Idaho. Water for irrigation is obtained from the Boise River and its tributaries which are regulated by storage in Arrow Rock and Deer Flat reservoirs. Distribution of water...
Disease control in hatchery fish
F. F. Fish
1947, Report
A direct method for controlling diseases among hatchery fish has long been sought as an alternative to the earlier technique of hand dipping.  A  simple, practical, effective method of direct pond treatment not only obviates all need for handling fish weakened by disease, but it would materially reduce the time...
Methods used in estimating the groundwater supply in the Wichita, Kansas well-field area
Charles C. Williams, Stanley William Lohman
1947, Eos, Transactions, American Geophysical Union (28) 120-131
This paper presents the methods used in studying the groundwater hydrology of an area in Harvey and Sedgwick Counties, Kansas, from which the city of Wichita derives its water supply. A summary of the data available for study is presented and several hydrologic factors are evaluated. The relationship between...
Instructions for flood frequency compilations
U.S. Geological Survey Water Resources Branch
1947, Report
These instructions are designed to facilitate work in this field, but are not to be considered as final and complete. They will be revised as needed to incorporate new ideas and experience gained in this field. For that reason, if use is planned any great period after the date shown...
