Surface Oil Spill Bioremediation

Petrox microbes provide quick response surface oil spill bioremediation.  Petrox can be applied to the oil surface with a backpack sprayer to initiate rapid bioremediation.  This approach protects surface water and vegetation with minimal surface traffic.

In the following example, an oil spill affected the vegetation and surface water at the edge of a lake. Contractors applied Petrox to the oil surface on vegetation and soil.  Periodic soil samples tracked the results.  After 90 days, the maximum and average concentrations decreased by more than 95% at a very low cost.

Surface Spills to Deep Subsurface Success With Petrox Bioremediation

Petrox bioremediation is used to remove petroleum contamination from soil and water under many different conditions.  From surface spills to deep soil and ground water contamination, Petrox has successfully removed the contamination and environmental risk.  This summary of case studies demonstrates the applicability of Petrox bioremediation to the full range and life cycle of petroleum spills.

Remove The Tea Bag Without Removing The Building

When a source of ground water contamination or contaminant vapors is present under a building, efforts to mitigate the spread of contamination may continue indefinitely with mounting costs.  Bioremediation may be used to remove the source of vapors or ground water contamination without damage to the building or interrupting operations.

There are many examples of this approach in the case studies on this site.  You can call us to find whether this approach is applicable to your site and the potential cost savings.

Fast Bioremediation Eases Site Development in Boston

Underground storage tank (UST) leaks from a former gas station contaminated shallow ground water under a parking lot for a commercial building.  The UST contamination was found during trenching for utilities.  As the presence of contamination prevented further property development, fast remediation was important to the stakeholders.

The size of ground water plume that resulted from leaching soil contaminants was estimated to be 5,000 square feet.    The contamination was mainly diesel-range petroleum constituents, with the highest concentrations in the aliphatic range, but there were also scattered detections of xylene, toluene, and ethylbenzene.

Petrox bioremediation was implemented in the ground water.  Three units of Petrox (165 gallons) were injected into the contaminated ground water through vertical injection wells located up gradient of the monitoring wells.

After a single inoculation of Petrox, the contaminant concentrations were reduced across the property.  The following table shows the overall reduction in both the volatile and semi-volatile range hydrocarbons.
