Hydrochemical and isotopic content of basalt groundwaters beneath the Hanford Site, Washington

Conference ·
OSTI ID:6814814
Information collected over the past 3 years, has significantly contributed to and advanced the hydrological understanding of groundwater flow systems within basalts at the Hanford Site. Hydrochemical and isotopic parameters analyzed include: major inorganics, trace elements, dissolved gas and stable and unstable isotopes. A summary of the hydrochemical data is presented. Stable isotopes are used to determine groundwater recharge areas and to determine evaporation histories of surface-water bodies. In addition they give insight to the type, origin, and age of groundwater. Deuterium, oxygen 18 and sulfur 34 have been used in these studies. Radionuclides have been used in a similar manner as stable isotopes. Discussed are uses of tritium, carbon 14, uranium, and chlorine 36 for the above mentioned purposes. (DMC)
