What if the smartest way to deal with "forever chemicals" is to stop trying to destroy them? In the latest episode of the Remediation Deep Dive, Max Flux and Sandy Lom unpack a recent Regenesis webinar with GSI PFAS Experts Drs. Charles Newell, David Adamson and Regenesis Vice President of R&D, Dr. Paul Erickson. The episode explains how PFAS Monitored Retention (PMR) and PFAS Enhanced Retention (PER) integrate natural processes with injected PlumeStop colloidal activated carbon to hold PFAS in place and protecting groundwater and ultimately drinking water resources. This proven approach has been deployed at more than 90 complex sites, including military installations, international airports and heavy manufacturing facilities. Performance data show over 99% reduction in PFAS mass discharge in treatment zones. And models project median retention of about 150 years for PFOA, 180 years for PFHxS and 870 years for PFOS. Whether you manage environmental liability, study the science or just care about what comes out of your tap, this episode shows why sometimes control is the best victory.

In this podcast episode, AI hosts Max Flux and Sandi Loam explore why successful in situ sorbent treatment depends less on how far an amendment travels and more on how evenly it reaches contaminant mass and groundwater-flow pathways. Drawing on field research, the discussion examines ten performance, monitoring, cost, and safety concerns associated with high-pressure injection of powdered and granular sorbents—including fracture-controlled placement, incomplete treatment-zone coverage, biased monitoring results, and contaminant rebound. They also discuss how low-pressure colloidal activated carbon delivery can achieve broader, more consistent coverage by moving through accessible aquifer pore spaces. The key takeaway: effective remediation requires distributing the sorbent—not fracturing the formation.

The latest Remediation Deep Dive podcast urges environmental practitioners to Rethink PFAS Soil Excavation and examines the financial, environmental, and long-term liability drawbacks of excavating and transporting PFAS-contaminated soil. AI hosts Max Flux and Sandi Loam discuss a New Jersey PFAS soil treatment case study highlighting how a low-dust colloidal activated carbon treatment immobilized PFAS in place, reducing leachability by more than 99% while eliminating surface waste, trucking, and landfill disposal. The episode makes the case that SourceStop can better protect soil and groundwater while lowering cleanup costs, carbon emissions, and lifecycle risks.
