National Park Borough PFAS Project

On January 22, 2020, the Borough of National Park, NJ (Borough) received notice from NJDEP that their samples collected for the fourth quarter exceeded the standard, or maximum contaminant level (MCL), for perfluorononanoic acid (PFNA).

By Spring 2020, T&M completed a feasibility study for the Borough, including evaluation and selection of treatment options for PFAS removal. The Borough required financial assistance to support the project, so T&M provided grant/loan management services, obtaining loan assistance from the New Jersey Environmental Infrastructure Financing (NJEIF) Program, New Jersey Environmental Infrastructure Trust (NJEIT) with $500,000 loan forgiveness, and a $1 million USDA grant. T&M was able to help the Borough fund the entire project.

T&M prepared all design documents and specifications for construction and commissioning of the Borough’s new PFAS treatment plant. The 500-gpm system will remove all PFAS to non-detect levels and is comprised of two trains of granular activated carbon vessels, in parallel lead-lag configuration with prefiltration bag filters. T&M also ensured all regulatory compliance, including preparation of all permits and supporting documentation required from state and local agencies. The NJDEP construction permit application was submitted to the NJDEP Bureau of Safe Drinking Water in October 2020 and a permit was issued in April 2021. Simultaneously, bid documents were finalized and submitted to the funding agencies.

Construction began in May 2022, with substantial completion in December 2022. The plant was placed in service on February 2, 2023.

Weekly testing started for four weeks from February 2 through February 21, 2023, and results were <2 ng/L or non-detect for PFAS.  Subsequent sampling events have yielded the same results of <2 ng/L.
