| Abstract: | Wetland restoration activities may disturb shallow ground-water flow dynamics. There may be unintentional sources of water flowing into a constructed wetland that could compromise the long-term viability of a wetland function. Measurement of naturally-occurring isotopes in the hydrosphere can provide an indication of provenance, flow paths or components, and residence times or ages of wetland ground-water flow systems. Hydraulic head measurements may not provide sufficient detail of shallow flow disturbances and can be complemented by analyzing isotopes in waters flowing through the wetland. Two north-central Indiana wetlands in the Kankakee watershed are being studied to determine the adequacy of wetland restoration activities. The native LaSalle wetland and the restored Hog Marsh wetland have contrasting ground-water flow regimes. The conservative water isotopes 18O, 2H, and 3H, and selected solute isotopes 13C, 14C, 15N, 34S, 87Sr, and 206-208Pb, demonstrate the complexity of ground-water flow in Hog Marsh compared to the established flow regime at the LaSalle wetland.Wetland restoration activities may disturb shallow ground-water flow dynamics.
