Diesel Fuel Contaminated Soil
SITE OWNER:
An Agricultural Chemical Production Facility
SITE SURVEY:
The future owners of the property decided to close and remove an underground storage tank (UST) that contain what was believed to be fuel oil. During the procedures for closing the site, it was discovered that a release had occurred. Initial laboratory analysis showed levels of 286 ppm of TPH (Total Petroleum Hydrocarbon) using the U.S. EPA Method 8015, modified. It was determined that the contaminate was diesel fuel.
METHOD:
BIO-SYSTEMS augmented insitu subsurface bioremediation process was selected to remediate the plume. BIO-SYSTEMS™ product (a proprietary blend of microaerophilic bacteria and micronutrients) was propagated on site and the resulting batch solution was placed through several borings and monitor wells into the contaminate plume. Routine PID readings of degradation components were monitored and recorded. Bioremediation began on March 13, 1991 and readings below clean-up levels were obtained on May 16, 1991. Final samples were obtained and forwarded to an independent laboratory for verification results. U.S. EPA Method 5030/8020 showed nondetect results.
COMMENTS:
By utilizing BIO-SYSTEMS bioremediation process and products, the property has no ties to a disposal site and PRP (Potentially Responsible Parties) liabilities from the diesel fuel contaminated tank site have been eliminated for the new owners of the property.
