Diffusion-Controlled Solute and Isotope Transport in the Milk River Aquifer System, Alberta, Canada: Implications for Dating Old Groundwater
{{output}}
Krypton-81 (81Kr) and chlorine-36 (36Cl) are among the few isotopic tracers capable of constraining groundwater residence times on 105-106 year timescales. In sedimentary aquifer systems bounded by low-permeability units, however, diffusive solute exchange can... ...
