Injectable permeable reactive barrier stops MTBE and benzene plume

Pilot-scale application proves effective solution to a long plume under a residential property and agricultural land

Fuel losses at a former petrol filling station in western Belgium, had resulted in the contamination of soil and groundwater with petroleum hydrocarbons and oxygenate additives. During the decommissioning of the site the source area was remediated, however a residual groundwater plume was left in place.

Having taken over the site from the previous owner, OVAM determined that this plume represented a potential environmental and human health risk. OVAM required active remediation to take place and Group Van Vooren worked with REGENESIS to develop a suitable strategy. Read the case study to learn more about this site, the remediation approach taken and the results achieved from the pilot test.

Case study highlights

• Pilot test proves injectable permeable reactive barrier (i-PRB) successful at reducing MTBE and benzene
• Technologies used: PlumeStop and ORC Advanced
• Monitoring data includes sampling event at 27 months post-injection
• Full-scale treatment scheduled
