Barnstable County PFAS Remediation PIP Update - July 2025

This Barnstable County public update meeting on July 30, 2025, focused on the ongoing PFAS remediation efforts at the former Municipal Fire Training Site. The county and its consultant, GZA GeoEnvironmental, provided detailed updates on site assessments, groundwater monitoring, ecological risk assessments, and remediation activities. Key procurement-related discussions included the selection of Regenesis as the remedial contractor through a competitive bid process to implement a full-scale permeable reactive barrier (PRB) system, following a successful pilot test. The PRB installation began in July 2025 and is expected to continue through October 2025, involving the injection of approximately 590,000 gallons of colloidal activated carbon to contain PFAS contamination. The meeting also addressed vandalism to the groundwater extraction system and ongoing repair efforts. Future plans include completing the phase two site assessment by early 2026, continued monitoring, and public updates. Stakeholders emphasized the importance of updating the conceptual site model and coordinating with nearby entities to address complex contamination sources.
