Monitoring and assessing natural attenuation capacity of an aquifer is not only a basic means for preventing and treating groundwater pollution, but also a hot topic in groundwater remediation technology research in abroad. In this paper, authors, taking a petrochemical site in North China Plain as a case study, estimate the aquifer natural attenuation amount of BTEX per year using microbial hydrogeological and chemical method, based on investigation of hydrogeological condition and pollution status in soil and groundwater as well as monitoring of BTEX concentration and some related chemical parameters in groundwater. This research result provides an empirical and basic data for assessment of natural attenuation capacity of petroleum contaminated sites in China
