A Practical Tool for PFAS CAC Barrier Design

PFAS Treatment Success at 17 Airport Sites

Max and Sandi dive into the peer-reviewed article, “Longevity of Colloidal Activated Carbon for In Situ PFAS Remediation at AFFF-Contaminated Airport Sites” by Carey et al. (2022), highlighting >90–99% PFAS reduction across 17 sites and the key factors driving CAC’s long-term performance.

A Practical Tool for PFAS CAC Barrier Design

Max and Sandi dive into the peer-reviewed article, “Tool and Database for Estimating Potential Longevity of Colloidal Activated Carbon Barriers for PFAS in Groundwater” by Newell et al. (2025), highlighting a new planning tool that simplifies estimating CAC barrier lifespan to guide design, planning, and PFAS plume management.

The Science Behind PFAS Monitored Retention

Max and Sandi dive into the peer-reviewed article, “PFAS Monitored Retention: A Framework for Managing PFAS-Contaminated Groundwater Sites” by Adamson et al. (2025), exploring how PFAS Monitored Retention (PMR) and PFAS Enhanced Retention (PER) use physical and chemical processes to slow plume migration and reduce risk—offering a cost-effective option where immediate threats are absent.

PFAS Treatment Face-Off

Max and Sandi dive into the peer-reviewed article, “A Cost Comparison of Pump-and-Treat and In Situ Colloidal Activated Carbon for PFAS Plume Management” by Birnstingl and Wilson (2024), highlighting how CAC delivers decades-long PFAS containment at one-third the cost of pump-and-treat—without the waste, energy use, or long-term liabilities.
