Chemical and isotopic evolution of ground water in the Midwestern Basins and Arches region
- Geological Survey, Columbus, OH (United States)
Aquifers in Pleistocene glacial deposits and underlying Devonian and Silurian carbonate rocks in the Midwestern Basins and Arches region are being studied as part of the US Geological Survey's Regional Aquifer Systems Analysis program. Water samples were collected from 20 wells in glacial and bedrock aquifers in northwestern Ohio and central Indiana coincident with directions of regional ground-water flow to determine chemical and isotopic changes that occur as ground water travels from regional recharge to discharge areas. The samples were analyzed for major and minor cations and anions, tritium, delta O-18, delta D; delta C-13, C-14; delta S-34; and delta Sr-87. The results of the isotropic analyses show that the regional ground-water-flow system dominates in northwestern Ohio, whereas local and intermediate ground-water-flow systems dominate in central Indiana.
