PetroFix Eliminates Hydrocarbon Plume Migration

Case study highlights:

• Permeable reactive barrier installed in underground car park in Northern Italy
• The barrier has stopped the offsite migration of a petroleum hydrocarbon plume onto a public road and archeological site.
• The in situ remediation has met the stringent cleanup target, positioning the site for regulatory closure, despite the challenges posed by the restricted access onsite.

This case study explains the installation of a PetroFix permeable reactive barrier below a new office building in Northern Italy. An excavation was conducted over a limited footprint to remove some of the more highly impacted soils. Beyond the excavation limits, pressure grouting was conducted to stabilize the residual soil contamination, prior to construction commencing. Once construction was completed, Planeta Studio Associato, a leading environmental consultancy based in Italy, collaborated with REGENESIS to develop an in situ remediation plan for treating the groundwater contaminant plume.
