Injectable PRB Provides Rapid Remediation of Chlorinated Plume Allowing Redevelopment within Months

Case study highlights:

• An in situ permeable reactive barrier (iPRB) was installed combining PlumeStop, S-MicroZVI and BDI Plus reagents
• Additional Design Verification Testing (DVT) was completed by REGENESIS prior to full-scale works
• Remediation targets and the client’s economic requirements were achieved on time and within budget, under a guaranteed contract

Stringent regulatory targets achieved in short timescale, despite challenging site conditions. Historical industrial activities at a former silver frames manufacturing facility in Central Italy had caused chlorinated solvent contamination in the subsurface, which was extending beyond the site boundary. As the site was undergoing redevelopment into residential buildings, the construction company had a strict deadline for remediation to be completed and so a strategy was needed to avoid the long-term installation of active pumping equipment onsite.
