PFAS plumes treated with colloidal activated carbon barriers unlock regulatory permission for full-scale remedial works 

We were contacted by two separate consultants working at a private and an international Airport in the UK. The groundwater at both sites was contaminated with PFAS. 

REGENESIS and the environmental consultancies worked closely with the airport managers and separate regulatory authorities to ensure that two successful pilot trials were delivered demonstrating the efficacy of PlumeStop® Colloidal Activated Carbon (CAC) in preventing the advection of PFAS contamination in groundwater. 



Case Study Highlights

  • For both sites, REGENESIS undertook Design Verification Testing (DVT) before installing 10m long pilot-scale barriers 

  • The target compounds PFOS and PFOA were reduced to at, or close to, detection limits. The total PFAS concentrations were also significantly reduced. 

  • The regulatory authorities granted permission for the progression of full-scale works on both sites

  • UPDATE : The full-scale works have now been completed at both sites and monitoring is ongoing
