Abstract

<p>Field demonstration tests of the bio-pile and land-farming purification methods for remediating petroleum contamination were performed using the Kunigami-maji soil which broadly exposed on surface of the northern half of Okinawa Island. These methods involve the addition of phosphorus and nitrogen compounds or Ryukyu limestone particles to petroleum-contaminated soil. Both methods were found to be effective. The addition of Ryukyu limestone particles shortened the time needed for Total Petroleum Hydrocarbons (TPH) degradation to begin. Land-farming purification with no artificial air supply proved effective for the remediation of petroleum-contaminated Kunigami-maji soil. The lowered water content and pH neutralization may encourage the activation of petroleum-degrading microbes. In practical use, the relationship between petroleum odor and TPH concentration should be investigated with a pilot test on site. This pilot test determines the required period for purification from the TPH removal rate. The field demonstration tests discussed in this study give reference data gathered with nourishment and different of purification-promoting mthods.</p>
