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 for validation. The following applica... https://fitnessgravesyardes.shop/product-category/right-crank-arm/
