Abstract
A total of 19 Ohio stream and ground waters were sampled and analyzed for total Sr and Sr87/Sr86 isotopic ratios in an attempt to evaluate the potential usefullness of the Sr87/Sr86 ratio as a tracer of water origin. Samples were collected in order to provide a wide geographic distribution and a variety of contacted lithologies. The measured Sr87/Sr86 ratios range from about 0.708 to 0.713, with the higher ratios occurring in eastern Ohio and the lower ratios in the west. It is felt that this trend reflects the change in the dominant lithology of the Paleozoic sediments across Ohio. In the east clastic sediments predominate, whereas in the west limestone becomes a more important component of the sedimentary sequence. Most limestones of Paleozoic age or younger are known to have Sr87/Sr86 ratios of approximately 0.708, whereas shales have a wide range of higher values. Thus the Sr87/Sr86 ratios in western Ohio may reflect the greater proportion of limestone in the sedimentary column in this area. It is felt that the demonstrated variability of the Sr87/Sr86 ratio in Ohio waters, and its apparent dependence on lithology in the sampling areas, are sufficiently encouraging to warrant further study of the application of this parameter as a tracer in water studies.
