Case Study | In Situ PFAS Remediation Protects Offsite Environment at Airport in Norway

Case Study Highlights:

• Through nine months of monitoring, the two primary PFAS compounds of concern, PFOA and PFOS, have been reduced by 96% and 98%, respectively.
• SourceStop® Liquid was applied as a permeable sorptive barrier to reduce PFAS migration hydraulically.
• The permeable sorptive barrier was designed and implemented downstream of the excavation area to mitigate the ongoing dissolved-phase transport of PFAS during and post-excavation.

Article | Pandora’s PFAS Box: Life Cycle Exposure Considerations of Treatment Options for PFAS in Groundwater

In the Spring Issue of Remediation Journal, Linda Hall , PhD, John Wilson , PhD, and Jeremy Birnstingl , PhD, discuss PFAS exposure risks associated with pump-and-treat solutions for groundwater.

In This Article, Learn More About:

• Human exposure potential throughout the life cycle of various remediation technologies.
• A colloidal activated carbon technology used in situ, which avoids surface contamination, generates no PFAS waste, and eliminates PFAS risk and human exposure.
• The principal difference between pump-and-treat and in situ colloidal activated carbon.

Case Study | In Situ Remedy Replaces Pump-and-Treat and Achieves TCE/PCE Cleanup Targets

Case Study Highlights:

• Based on successful performance results, a pump-and-treat system was decommissioned in 2020, and the NYSDEC granted the site closure in August 2021.
• By not having to operate and maintain the pump-and- treat system, substantial energy and cost savings were realized in this period.
• Roux’s agile site management, making the switch from an ex situ to a PlumeStop in situ approach, saved time and money for their client.

Case Study | Permeable Reactive Barrier Installed in Underground Car Park in Northern Italy

Case Study Highlights:

• Installation of a PetroFix permeable reactive barrier below a new office building in Northern Italy.
• The barrier has stopped the offsite migration of a petroleum hydrocarbon plume onto a public road and archaeological site.
• The in situ remediation has met the stringent cleanup target, positioning the site for regulatory closure despite the challenges posed by restricted access.
