REGENESIS worked with RAKE Remediation and WDE Consulting to devise a fully integrated remediation strategy in order to provide accelerated remediation of a former petrol filling station.
The remedial strategy comprised:
The treatment comprised targeted excavation of the most impacted soils, around the former UST location. This was followed by ORC Advanced Pellet application into the excavation to address the residual dissolved phase.
LNAPL was removed from the groundwater in the surrounding plume using a P&T system. This was enhanced with PetroCleanze to provide temporary desorption of contamination in the smear zone. This enabled the P&T system to remove a greater amount of contamination in a short period and avoid rebound.
ORC Advanced slurry was injected in two lines within the dissolved phase plume in order to degrade, through ENA, the migrating contamination and prevent any further egress from site.
