Injectable permeable reactive barrier prevents offsite risk

Fuel losses at an operational petrol filling station (PFS) in the UK resulted in light non-aqueous phase liquid (LNAPL) seasonally building up under the forecourt. High levels of dissolved phase contamination was shown to be migrating beyond the site boundary and providing a potential off-site liability.

It was decided that voluntary remediation should be completed to prevent offsite advection and SLR Consulting concluded that the most sustainable remedial design for the site would be the installation of an injectable permeable reactive barrier (IPRB) using PetroFix® colloidal activated carbon. SLR partnered with REGENESIS to design and apply the solution.
