First Application of PetroFix at Petrol Filling Station in Sweden

Case study highlights:

• The integrated remediation treatment strategy ensured that optimum treatment efficiency was maintained throughout the phases of works
• The amount of excavation and offsite disposal was minimized
• All underground infrastructure remained in situ
• All works were completed at an active petrol filling station with minimal disruption to the commercial operations of the facility
• 12-month period monitoring results show reductions of >98% of the gasoline range of petroleum hydrocarbon concentrations in the groundwater

RGS Nordic was asked by Circle K to remediate groundwater contaminated with gasoline at an active Petrol Filling Station (PFS) in Nykvarn, Sweden. During the site investigation, petroleum hydrocarbon contamination was identified within the fill material around the underground storage tank (UST) farm.RGS Nordic was required to deliver a remediation strategy that posed minimal disruption to the commercial operations of the PFS. The chosen remediation strategy combined targeted excavation, in situ chemical oxidation (ISCO), in situ sorption, and enhanced aerobic biodegradation using a range of complementary REGENESIS technologies: RegenOx®, ORC-Advanced® and PetroFix®.
