RESEARCH - Water Samples for Tritium and Deutrium Analyses UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Water Resources Division Washington 25, D.C. In reply refer to: September 4, 1958 Code 4050 0001 GROUND WATER BRANCH MEMORANDUM NO. 59.10 To: District Chiefs and Staff Officials (GW) From: Chief, Ground Water Branch Subject: RESEARCH - Water Samples for Tritium and Deutrium Analyses A tritium-deuterium research program was initiated during fiscal year 1958. The principal objective is to explore the possible uses and value of tritium and deuterium in hydrologic research. The overall responsibility for the tritium portion of the program has been assigned to the Ground Water Branch but will call for close co-operation with the Quality of Water Branch and collaboration with the Geologic Division. C. W. Carlston of the Ground Water Branch has been designated project leader and L. L. Thatcher of the Quality of Water Branch will serve as the principal collaborator on the tritium portion of the program. Mr. Irving Friedman of the Geologic Division is doing research on deuterium in hydrologic investigations. Although most of the laboratory capacity for tritium analyses in the 1959 fiscal year will be devoted to two major research projects, it will be possible to analyze a few additional samples. This memorandum with the attached statement on "Tritium and Deuterium program of the Water Resources Division" is given Division-wide distribution in order that all Division Offices and Staff Officers may have the opportunity to consider proposals for tritium analyses during this fiscal year and to consider possible uses of tritium in hydrologic studies. Owing to the small laboratory capacity, tritium analyses can be made only for projects where the analyses may help to solve a definite hydrologic problem such as those described in the accompanying report. Offices desiring tritium analyses should send in proposals to C. W. Carlston, Ground Water Branch, Washington 25, D.C. The proposals should state clearly and fully the geologic and hydrologic setting of the source of the samples and the possible value of information on tritium content. No samples should be collected until the proposals are approved, at which time instructions on collecting and packaging the samples will be supplied. There will be no charge for the analyses of samples collected on this program; however, collection and shipment charges must be borne by local offices. (s) A. N. Sayre Distribution: A, B, F (all)
