One of Bay West’s key PFAS projects involves a remediation of a former fire training area at a former DoD facility in Michigan. Firefighting constituents, including aqueous film-forming foam that contained PFOA and PFOS, were used to extinguish fires during training activities at the site. Concentrations of PFOA and PFOS at the site have been over 100,000 nanograms per liter (ng/L) near the source area. The fire training pit is located in an upland area of the site upgradient of a wetland area.

A liquid granulated activated carbon (LGAC) groundwater pump and treat (P&T) system was designed/constructed in 2014 to address on-site PFOA and PFOS concentrations exceeding the 2009 Provisional Health Advisory Values (HAV) of 400 and 200 ng/L, respectively, to achieve Michigan non-acute groundwater surface water interface (GSI) standards of 20 ng/L PFOS and 40 ng/L PFOA. At the time of the FT-02 treatment system design and installation, much was unknown about PFOA and PFOS plume behavior, and/or the full-scale LGAC treatment of PFAS. Bay West has optimized, operated and maintained this system since 2016.
Bay West’s executed a pilot study to evaluate the effectiveness of Total Oxidizable Precursor (TOP) assay to gain insight into the total mass of PFAS present and the potential for additional bio-production of perfluorinated carboxylic acids (e.g. PFOA) from precursors not detectible by the more common PFAS analytical 537 method. The pilot study evaluated whether enzyme coupling with GAC and RemBind can cost-effectively extend the PFOS and PFOA operating life of the GAC units. Resin absorption, reverse osmosis treatment alternatives, and a complete GAC replacement were evaluated. Our pilot study results and recommendations were provided to the customer for system optimization opportunities.
Bay West supports the day-to-day activities at the site including coordinating project activities and meetings, arranging for site visits and tours, and acting as the on-site client representative. Bay West supports the DoD in meetings, where the status of restoration activities is reported to the project stakeholders and regulators. Since the system was constructed, PFOA and PFOS regulatory criteria are now orders of magnitude lower. Bay West compiles data and develops meeting agendas and presentations to communicate restoration activities to the project stakeholders and regulators. Bay West also arranges the venue for the meetings and takes meeting minutes to document the topics discussed. The on-site staff also perform routine site inspections and property owner interviews to verify that the land use controls are in compliance.
Excellent response time and made quick work of a cleanup with many moving parts.
