PetroSurf is a concentrated surfactant material used in-situ to break up and mobilize large quantities of diesel, gas, and heating oil in contaminated soils prior to engaging in bioremediation with PetroClean.
PetroSurf is typically diluted either 1:20 or 1:40 in water depending on the nature of the contaminant and the soil type, injected into the contaminated zone, allowed some residence time to mobilize the contaminants in the soil, and then removed via vacuuming. This process removes a significant amount of free-phase contaminants.
The blue color of PetroSurf aids the operator in telling when the dilute PetroSurf and mobilized oil removal is complete.
After the mobilization/removal process is complete, PetroClean is often injected and allowed to remain in-situ in order to further remediate any residual contamination.
Because PetroSurf is supplied in highly concentrated form, is more cost-effective on a per-job basis than typical competitor products.
