Determination of beta activity in water
F. B. Barker, B.P. Robinson
1963, Water Supply Paper 1696-A
Many elements have one or more naturally radioactive isotopes, and several hundred other radionuclides have been produced artificially. Radioactive substances may be present in natural water as a result of geochemical processes or the release of radioactive waste and other nuclear debris to the environment. The Geological Survey has developed...
Chemical quality of surface waters in Pennsylvania
Charles N. Durfor, Peter W. Anderson
1963, Water Supply Paper 1619-W
Pennsylvania has an abundant supply of surface water of good quality. The average rainfall over the 45,300 square miles in the State is about 42 inches per year. Of this amount, about 50 percent appears in the streams as runoff. The combined mean annual runoff of the Delaware, Ohio, and...
Ground-water levels in observation wells in Oklahoma, 1956-1960
D.L. Hart Jr.
1963, Open-File Report 63-150
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect on a systematic basis records of water levels in selected observation wells. These water-level records: (1) provide an index to available ground-water supplies;...
Methods of collecting and interpreting ground-water data
1963, Water Supply Paper 1544-H
Because ground water is hidden from view, ancient man could only theorize as to its sources of replenishment and its behavior. His theories held sway until the latter part of the 17th century, which marked the first experimental work to determine the source and movement of ground water. Thus founded,...
Development of a hand portable rainfall-simulator infiltrometer
I.S. McQueen
1963, Circular 482
Comparisons of relative infiltration of summer thundershowers into undisturbed and treated western dry lands are necessary for guidance of future treatment practices. A system designed for measuring infiltration of simulated rainfall into small plots of undisturbed soil that can be hand-carried to sites inaccessible to vehicles has been developed. Disturbance...
