SITE:

Petroleum contaminated insitu soils and waters.

BIODEGRADED MATERIAL:

 

Gasoline

SITE SURVEY:

 

The contamination of the soil and groundwater was a result from the petroleum release of an underground storage tank system that was removed from the site. It was found that the contamination in the groundwater was causing the contamination to migrate into other areas. Samples were obtained and the initial laboratory samples revealed that the levels of contamination were actionable. The soils encountered were primarily sand and clay.

METHOD:

 

Insitu bioremediation was selected to enable the site to be cleaned-up and put back into productive use with the least amount of disruption to the adjacent property, the clients business and the site itself. First the two underground storage tanks were removed and two new underground storage tanks were installed in a new tank field location. Soil excavated from the old tank field and all visibly stained soil was removed, stockpiled on site and treated. 200 feet of 4 inch PVC was then installed in the contaminated area for an insitu remedial irrigation system. The H-10™ product placement was made via the irrigation system. Once the Bio Rem H-10™ product was applied, there was no other addition of oxygen sources or other nutrients needed to remediate the site. The contaminated area was then tested after remediation. Testing for this projects progress and results was taken bi-monthly checking the soil and well readings with a photo ionization detector (PID). When acceptable levels were reached using the PID, final water and soil samples were sent to an authorized laboratory for analysis.

 

The results of the laboratory analysis confirmed there were no actionable levels after remediation. The samples were analyzed using U.S. EPA Method SW846-8020, 418.1, and 8021B as required by the Ohio Bureau of Underground Storage Tank Regulation Board.
