Estimation of In-Situ Groundwater Conditions Based on Geochemical Equilibrium Simulations
This paper presents a means of estimating in-situ groundwater pH and oxidation-redox potential (ORP), two very important parameters for species migration analysis in safety assessments for radioactive waste disposal or carbon dioxide sequestration.The method was applied to a pumping test in a deep borehole drilled in a tertiary formation in Japan L
