Abstract

The determination of the redox potential (Eh) of underground water in repository site is extremely important for long-term safety evaluation. The present study has developed a novel methodology for Eh estimation of the underground water of Beishan borehole 28 (BS28), which consists of the on site logging, the modelling with the characteristics of sampled water and rock cores and the verification study dedicated to evaluate the reliability of the Eh measurement. An Eh range between − 56 and 118 mV is suggested for BS28 underground water at 365–690 m deep after a thorough analysis of both modelling data and measurements.
