摘要:
The utilization of a venting strategy to remove gasoline vapors from contaminated soil strata was investigated in this exper‐ment. A contained gasoline “leak”; was created in a large outdoor facility which simulated soil strata and a static water table. An air flow was established, and vapor samples taken before, during, and after venting were checked for hydrocarbon content. The effluent air was regularly sampled for carbon dioxide and total hydrocarbons. Carbon dioxide data were used to estimate the amount of microbiological activity, and total hydrocarbon data were used to calculate the total amount of gasoline removed by venting. Hydrocarbon condensates from the effluent air were collected periodically and the compositions of these condensates were compared to the compositions of the starting gasoline and the residual that remained in the soil.
