This paper presents a means of estimating in-situ groundwater pH and oxidation-redox potential (ORP), two very sukrensi.com 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 for validation.The following application examples are presented: when applied to several other pumping tests at the same site, it could estimate distributions click here of the in-situ groundwater pH and ORP; applied to multiple points selected in the groundwater database of Japan, it could help estimate the in-situ redox reaction governing the groundwater conditions in some areas.
