||A total of 27 groundwater samples from the Scioto River drainage basin, Ohio has been analyzed for strontium and calcium concentrations and strontium-isotopic compositions. Ground waters which emanate from carbonate bedrock are characterized by 87Sr/86Sr ratios in the range 0.708 - 0.709; unusually high Sr/Ca ratios in these waters identify celestite lenses within the carbonate as the dominant source of strontium. Underground waters from clastic bedrock, principally shale, have 87Sr/86Sr ratios which vary from about 0.710 to about 0.713m and low Sr/Ca ratios. Thus there are two basic groundwater types from bedrock within the basin which can be identified by these two parameters. (Modified author abstract)
