New York Brownfield Site Treated for PFAS Achieves Closure

Case study highlights:

• NYSDEC certifies cleanup requirements achieved, making the site eligible for redevelopment
• Brownfield cleanup program’s green remediation policy leads to PlumeStop for PFAS treatment
• PlumeStop barrier for PFAS treatment is a key component in pursuit of site closure
• Skillfully managed PlumeStop application achieves GSR and cost reduction objectives

This case study reviews a 25-acre former refinery located in a mixed-use industrial/commercial area that was contaminated with PFAS. Benchmark Environmental Engineering & Science, PLLC & TurnKey Environmental Restoration, LLC (Benchmark & TurnKey), a leading engineering and redevelopment consulting company headquartered in Buffalo, New York, engaged REGENESIS for an in situ remedy that would effectively and economically cut off the plume and prevent migration of PFAS offsite. The site was entered into the New York State Department of Environmental Conservation’s (NYSDEC’s) Brownfield Cleanup Program (BCP) to facilitate its commercial redevelopment. Remedial alternatives were evaluated for a comprehensive site closure strategy, and approaches were scored based on NYSDEC’s Green Remediation Policy Document DER-31, which considers the “environmental impacts of treatment technologies and remedy stewardship over the long term.”
