Feasibility study carried out at the site prior to the full scale study showed that the introduced bacterial consortium effectively adapted to the local environment of the soil at bioremediation site. The soil samples were collected from the contaminated fields after treatment with bacterial consortium at different time intervals and analyzed by gas chromatography after extraction with hexane and toluene. At time zero (just before initiation of bioremediation), the concentration of total petroleum hydrocarbons in the soil (25-cm horizon) of plot A, B, C and D was 30.90 %, 18.80 %, 25.90 % and 29.90 % respectively, after 360 days of treatment with microbial consortia was reduced to 0.97 %, 1.0 %, 1.0 %, and 1.1 % respectively. Whereas, only 5 % degradation was observed in the control plot after 365 days (microbial consortium not applied).
在全面研究之前，在现场进行了可行性研究，结果表明，引入的细菌联合体有效地适应了生物修复现场土壤的当地环境。从用细菌联合体处理后的受污染田地采集土壤样本，用己烷和甲苯提取后，通过气相色谱进行分析。在时间为零（生物修复开始之前）时，A、B、C 和 D 地块 25 厘米深度土壤中总石油烃的浓度分别为 30.90%、18.80%、25.90%和 29.90%，经过 360 天微生物联合体处理后，分别降低到 0.97%、1.0%、1.0%和 1.1%。而在 365 天后，对照地块（未应用微生物联合体）仅观察到 5%的降解。
