Remediation project wins ‘Brownfield Redevelopment Project of the Year’ in Ground Engineering Awards

At the site of a former storage and distribution depot in Coventry, the soils and groundwater were impacted with petroleum hydrocarbons from previous site usage, which included a petrol filling station that had been located just north of the site and also across part of the site itself. Cundall created a multi-phased remediation strategy with Alto Construct to deal with the soils and asked REGENESIS to carry out the groundwater remediation.

REGENESIS installed a PetroFix activated carbon permeable reactive barrier at the edge of the site to capture and promote the biological degradation of high levels of dissolved phase contamination migrating on-site, to protect the redevelopment site as well as the adjacent river.

Case study highlights

  • 40m long in situ barrier installation completed within 5 days
  • Small working footprint – no disruption to construction works
  • This alternative solution provides immediate and long-term groundwater treatment
  • GE Awards 2020 winner:  The judges commented on the innovative method and recognised the reduced programme and significantly reduced quantities of soil sent to landfill, minimising environmental impact.
