  4. Abstract:
  5. The development of industries has contaminated the soil both below and above the water table. Although extensive research has been conducted on the contaminant transport through saturated domain, the knowledge about the mechanism of contaminant transport in the vadose zone is rather limited. Therefore, this study aims to introduce an instrumented soil column to study bio-logical methods as an eco-friendly approach to remove soil pollutants. The soil column is equipped with moisture measuring sensors and sampling ports. Therefore, the new apparatus can be used to monitor flow of water and contaminant because soil moisture distribution affects the microbial degradation of hydrocarbons. The performance of new device is explored and dis-cussed via conducting a preliminary bioremediation test on a compacted soil column initially contaminated with 7% (w/w) of diesel. The results in terms of microbial activity are interpreted based on the temporal and spatial variations in the total petroleum hydrocarbon (TPH). © 2023 selection and editorial matter, Askar Zhussupbekov, Assel Sarsembayeva & Victor N.
