This research employed multiple isotopic and geochemical tracers to build on previous studies of a restored wetland at Hennepin and Hopper Lake in central Illinois. This study provides new hydrogen and oxygen isotopic data as well as major solute concentrations to elucidate both water inflow and mixing as well as biogeochemical processes. This study supports previous findings that groundwater is the principal water source, there is little hydrologic interaction between the Illinois River and the restored wetland, and geochemical processes in the wetland would support its use as a future contaminant sink.
