| Abstract: | Volatile organic contaminants can be removed from soil using technology of soil vapor extraction(SVE).This paper describes an on-site experiment of SVE used for contaminated soil remediation at a coking plant in Beijing,in which variation of soil vapor pressure is monitored and radius of influence(ROI)of soil permeability is calculated.Results of the field test are used to calculate the ROI and to determine air permeability of soil based on a formula or the data of monitoring wells which describe changes of... |
