PetroClean and PetroSurf Success Stories

Diesel Fuel Release

A fuel company located in Virginia had a failure of a buried diesel fuel transfer line resulting in release of over 1300 gallons of diesel fuel to the environment. This release resulted in significant impacts to soil in the general area of the line failure as well as groundwater downgradient to the site. Monitoring wells were installed to determine the level of contamination. Within the wells, as much as 1.3 feet of diesel fuel was found floating on the surface of the groundwater. Over 60 tons of diesel-contaminated soil was removed from the immediate area of the leak.

PetroClean was injected into the contaminated area to mobilize any soil-adsorbed diesel fuel and bioremediate any unrecoverable diesel fuel. Application was via injection into wells drilled in the impacted area.

In monitoring events subsequent to PetroClean injection, free-phase product rebound in the monitoring wells was not noted and continuously dropping dissolved-phase diesel levels indicate that the microbes contained in PetroClean are rapidly degrading residual levels of diesel fuel within the impacted zone.

Fuel Oil Release

The Virginia Department of Environmental Quality (VDEQ) has determined that PetroClean effectively bioremediates heating oil. For home heating oil tank releases within the Commonwealth of Virginia, the VDEQ has authorized the use of PetroClean to bioremediate any residual impact to soils not removed as part of heating oil release remediation activities.

Gasoline Release

A fuel company located in Virginia had failure of an underground gasoline storage tank, resulting in a release of gasoline to the environment. Because of the nature of the site, removal of contaminated soil was not possible, so PetroSurf was initially injected around the periphery of the site and removed to recover as much free-phase product as possible. Subsequently, dilute PetroClean was injected and allowed to remain in-situ. Subsequent site monitoring 30 days post-injection indicated that gasoline impacts were significantly reduced. Further site monitoring indicated even more reduction in gasoline impacts at the site. The site was determined to be effectively bioremediated and was then closed by the VDEQ.
