Successfully managing PFAS impacts requires more than a single technology or remediation approach. From defining the nature and extent of contamination to selecting and implementing effective treatment strategies, environmental professionals are increasingly being asked to make decisions that balance technical performance, constructability, regulatory requirements, long-term liability, and project cost.
This four-part webinar series explores practical approaches to PFAS investigation, characterization, source zone management, plume remediation, and destructive treatment. Attendees will gain insight into field-proven technologies, implementation considerations, and lessons learned that can help improve project outcomes and support more informed remediation decisions.

Part 1: PFAS Site Investigation in Practice: Drilling, Characterization, and WaterlooAPS™ Applications
August 26, 2026 | 1PM EST
Presenters: Casey Moore and Rob Danckert
PFAS investigations present unique challenges due to low detection limits, complex groundwater behavior, and the potential for cross-contamination during drilling and sampling activities. Learn practical field considerations for PFAS investigative drilling and discover how high-resolution characterization tools such as WaterlooAPS™ can improve conceptual site models and strengthen remediation planning.
Part 2: Chemistry and Delivery Approaches for PFAS Source and Plume Remediation
September 23, 2026 | 1PM EST
Presenters: Eliot Cooper, Paul Lear, Ph.D and Deborah Shaffer (Schnell) P.E.
As organizations move from site investigation to remedy selection, understanding how remediation chemistry and delivery methods work together becomes increasingly important. Explore how colloidal carbon barriers, soil mixing, and trenchless permeable reactive barrier technologies can be applied to address PFAS impacts in both source zones and groundwater plumes.
Part 3: Thermal Remediation for Total PFAS Destruction in Contaminated Source Zones
October 21, 2026 | 1PM EST
Presenter: John LaChance
Many PFAS treatment approaches focus on containment or transfer rather than destruction. This webinar reviews field-demonstrated high-temperature thermal treatment technologies and examines how they can achieve destructive treatment of PFAS in impacted soil, sediment, and vapor streams while addressing emissions management and treatment verification requirements.
Part 4: PFAS Source Zone Remediation: ISS Applications and Potential Trenchless PRB Use Cases
November 11, 2026 | 1PM EST
Presenters: Paul Lear, Ph.D and Deborah Shaffer (Schnell) P.E.
PFAS source zones can continue contributing contamination to groundwater long after initial releases occur. Learn how in situ stabilization/solidification (ISS) can be used to reduce contaminant mobility while exploring potential applications for trenchless permeable reactive barriers in areas where traditional excavation or mixing methods may be limited by site access, depth, or surface disruption constraints.
Join us live for all four sessions or register once to receive access to the webinar recordings and watch on demand. Gain practical insights from experts on PFAS investigation, characterization, remediation, and treatment technologies that can help support better project decisions across the entire site lifecycle.
