Rapid groundwater cleanup: PetroFix reduced benzene by 99.7%, toluene by 99.9%, ethylbenzene by 99.3%, total xylenes by 99.8%, and both aliphatic and aromatic TPH by more than 99% within five months of treatment.
Minimal disruption to active operations: The in situ application was completed in a single day using just three injection wells, allowing the gas station to maintain normal operations while remediation was performed.
Immediate and long-term treatment benefits: PetroFix increased the sorptive capacity of the aquifer matrix for immediate contaminant reduction while supporting ongoing biodegradation to address residual petroleum hydrocarbons over time.
Cost-effective remediation for constrained sites: The treatment was completed within the projected budget and schedule, demonstrating an efficient, flexible solution for petroleum hydrocarbon remediation in space-limited, active commercial settings.
At an active gas station in São Bernardo do Campo, Brazil, petroleum hydrocarbon impacts in groundwater persisted despite previous remediation efforts. To achieve rapid concentration reductions and address long-term contaminant mass associated with matrix back-diffusion, PetroFix® colloidal activated carbon was applied through a focused in situ injection program. The treatment was completed with minimal disruption to ongoing operations and delivered greater than 99% reductions in BTEX and TPH concentrations within just five months.
