Abstract

This work presents a case study of assessing the overall performance of land farming technique performed at an oil-contaminated site. The land farming was conducted at a 70,000 m2 site contaminated with diesel, JP-8-diesel, or lubricant due to underground leakage from the oil storage tanks. Five treatment plots were operated in the tests, in which the concentration changes of xylene and TPH in the soil were separately monitored in two and 15 batches, respectively. The overall performance of the remediation process was assessed by estimating the pseudo-first-order rate constant (kobs) of each test. The obtained kobs values of TPH degradation ranged in 0.054~1.287 mg/kg/day, with the average kobs being 0.021 mg/kg/ day, which is close to the degradation rate of 0.025 mg/kg/day, the target kobs value set in the design of the process. The degradation rate showed an inverse relation with the contaminant level in the soil, but was not influenced by soil texture. Temperature showed a positive correlation with the degradation process, with its impact being most pronounced in July. TPH initial concentration and temperature showed a low level of correlation (R2 = 0.4) with the decomposition rate constant. The data obtained in this work can serve a useful framework for establishing a quality management strategy for soil remediation projects involving landfarming technique.
