This study was conducted to evaluate in-situ bioremediation ability of Bioil-D, microbial material for oil degradation, at a gas station that had been treated by SVE system. TPH concentrations and total contaminated soil volume were rapidly decreased after Bioil-D treatment. The performance of Bioil-D was also estimated based on the observation of microbial population at the soil samples and $CO_2$ concentration produced at the extraction wells. The field study showed a successful work of Bioil-D.

Landfarming and a microbial agent, Bioil-D, were used to treat diesel-contaminated soil. The microbial agent was applied to the contaminated soil in a concentration of 5$\times$10$^2$ cfu/soil(g) and the total amount of microbial agent, 210$\ell$, was sprinkled on the soil four times for 24 days during 50 day-remediation period. The remediation goal, lower than 800mg/kg of TPH, was achieved from 5, 707 mg/kg of TPH within 50 days. The total number and activity of indigenous microorganisms were increased by 100 times after the microbial agent, Bioil-D, was applied to the contaminated soil.

Landfarming and a microbial agent were used to treat dilsel-contaminated soil. The microbial agent was applied to the contaminated soil in a concentration of 5$\times$102 cfu/soil(g) and the total amount of microbial agent, 210 l , was sprinkled on the soil four times for 24 days during 50 day-remediation period. The remediation goal, lower than 800mg/kg of TPH, was achieved from 5,707mg/kg of TPH within 50 days. The total number and activity of indigenous microorganisms were increased by 100 times after the microbial agent, Bioil-D, was applied to the contaminated soil.
