remedial investigation and feasibility study for PFAS

remedial investigation and feasibility study for PFAS
Saint-Gobain Performance Plastics
eastern United States

helping investigate and address contaminants at multiple sites

At or nearby several active and former manufacturing facilities owned by Saint-Gobain Performance Plastics (SGPP) in the eastern United States, per- and polyfluoroalkyl substances (PFAS) have been detected in public water supplies and private wells. The sites are located in multiple states in the eastern U.S. and involve a complex group of potentially responsible parties working with local, state, and federal regulatory authorities.

Barr is part of a collaborative consultant team retained by SGPP to complete a fast-tracked remedial investigation and feasibility study (RI/FS). The work includes evaluating potential release mechanisms from multiple facilities, including sampling and analyses of process streams, air emissions, and process wastewater. Barr has conducted PFAS water-treatment bench testing and pilot testing and evaluated treatment technology options, including granular activated carbon and ion exchange. Extensive multi-media investigations at each site have included collecting soil, groundwater, surface water, and sediment samples; performing interior building surveys and sampling; and reviewing historical and background materials. All work has been completed following intense quality assurance protocols.

Barr serves as the lead consultant for developing and refining complex site conceptual models at each project through iterative efforts, including complex, coupled air dispersion, groundwater flow, and fate and transport modeling. Various remedial strategies are being considered to address the risk concerns for PFAS.

The work has been closely coordinated with each state’s regulatory authorities as Barr helps SGPP understand the implications for their sites and as the science and regulations associated with this emerging contaminant continue to evolve.
