Statement of Qualifications: Per- and Poly-Fluorinated Alkyl Substances (PFAS)Why TRC?TRC provides comprehensive services for PFAS investigations, including planning, sampling, analysis, compliance, risk assessment and remediation consulting. We have served a wide range of private and public clients from different sectors and industries, including manufacturing, transportation and petrochemical.
We understand our clients’ goals, and we embrace them as our own. Our clients depend on us to be their trusted adviser in designing and implementing solutions to the toughest challenges. Building upon our long history as expert problem-solvers, we excel in developing creative options and implementing the optimal solution that meets or exceeds each client’s expectations.
TRC’s Center for Research and Expertise (CORE)TRC has a team of multidisciplinary technical experts to encourage knowledge transfer, streamline access to experts and enhance TRC’s growth and competitiveness in the marketplace. The CORE was designed to promote technical excellence, to work at the forefront of emerging challenges and solutions, and to contribute to the technical advancement of our professional, academic, and client communities.In fact, our experts educate representatives of regulatory agencies, attorneys, and our clients about investigation, fate and transport, and remediation of PFAS. The CORE experts are specifically dedicated to researching and understanding technical, regulatory, and remediation issues associated with emerging contaminants.
Creative, dedicated experts delivering results you can rely on.
We understand the unique sampling challenges.TRC is keenly aware that PFAS are ubiquitous, which presents both a sampling challenge and an important consideration in source attribution by regulators. TRC has experience with the special precautions for sampling soil and groundwater for PFAS. We use our PFAS-specific standard operating procedures for field sampling PFAS, and we ensure no PFAS materials are used in our sampling process. We refrain from the use of certain cosmetics when sampling and packaged foods are not brought on site. These are just a few of the many safeguards we have in place.
Analytical and Data Assessment ExpertiseTRC employs a quality assurance team dedicated to the evaluation, assessment, and validation of analytical data. Additionally, our relationships with analytical laboratories capable of performing the specialized analyses associated with PFAS is key in our ability to test accurately. Our chemists have experience validating analytical data for PFAS and understand the importance of the branched and linear isomer quantitation.
Experience
Former Chromium Plating Site, New England TRC performed sampling of groundwater and drinking water for PFAS at a federal-lead Superfund Site as part of a Remedial Investigation/Feasibility Study. PFAS were detected in these media, and we are currently planning for additional sampling to define the nature and extent of PFAS. We are working with EPA Headquarters and the local EPA Region to establish protocols for PFAS on federal lead sites.
Superfund Site, International Airport, New JerseyTRC collected PFAS data in soil and groundwater for investigative purposes with the EPA as the driving force. Data were collected for 10 of the linear and branched PFAS. Currently, PFAS are not being actively remediated but several of the areas exhibiting elevated PFAS are undergoing groundwater remediation for other chemicals (e.g., VOCs) via granular activated carbon technology and therefore the PFAS are also being removed to a certain extent.
Petrochemical – Plastics Precursors Facility, Decatur, AlabamaTRC collected groundwater samples for PFAS because our client had installed a large production well to supply water to its on-site environmental education center (a “lab” that included a large pond used by local schools for environmental/ecological awareness) and learned that a neighboring facility’s groundwater contained elevated PFAS. We found that PFAS had migrated from the neighboring facility’s property into the supply well and the lab’s pond. The neighboring facility paid to close our client’s well and subsequently drained and excavated the pond, placing a cap over the area.
CERCLA Site, DelawareAs part of the 5-year review at a CERCLA site in Delaware, TRC was required by the EPA to sample for PFAS in groundwater. The remediated site was a former electronics manufacturing facility where the use of PFAS was unlikely. A historic chrome plating operation at or adjacent to the CERCLA site probably used PFOS as a mist suppressant over its chromic acid bath tanks. Releases from these plating operations were the likely source of the PFAS.

FOAM DISCHARGE SITES
Former Manufacturing Site, MaineTRC has performed groundwater sampling for PFOA and PFOS as part of a USEPA Brownfields Program Phase II Environmental Site Assessment. The site is located adjacent to and partially within a watershed area for municipal water supply. Previous, non-TRC investigations resulted in detections of PFAS in groundwater in the aforementioned offsite water supply wells. To delineate potential impacts to site media, three wells along the site perimeter were sampled for PFAS to assess potential for PFOS and PFOA to be migrating onto the site.
Former Microelectronics Manufacturing Facility Site, New EnglandTRC has performed sampling of soil, groundwater, surface water, and sediment for PFAS at a former RCRA site (state lead). The sampling was part of a State-requested PFAS investigation at a site with a pre-existing groundwater remedial system to recover and treat volatile organic compounds (VOCs). TRC prepared a Site Investigation Workplan (SIWP) that received State approval and included detailed protocols for sampling several media for PFAS while preventing cross-contamination. The SIWP calls for collection of four quarterly rounds of groundwater sampling, and a report that includes an evaluation of PFAS fate and transport. Sampling of the existing groundwater treatment system demonstrated that enhanced liquid phase granular activated carbon effectively removed PFAS. TRC completed the design and is currently constructing replacement groundwater treatment systems for VOCs, including resin absorption components for contingent treatment of PFAS.
International Airport, New YorkTRC designed a sampling plan and collected PFAS data in water/storm water for investigative purposes and as part of an Information Request received from NYSDEC under the Environmental Benefit Permit Strategy (EBPS). PFOA and PFOS have been detected in water above the EPA health advisory (70 ng/L) and we are currently evaluating potential sources, background sources, and working on identifying and isolating potential inflow to the storm water drainage system. Following the investigation phase, TRC will be recommending and designing a remedial option(s) to swiftly address the potential discharge of PFAS to the environment.
Municipal Landfill, New York. TRC will be responsible for characterization of a closed municipal landfill with one area of nearby residences and several nearby surface water bodies. This landfill is believed to have accepted industrial waste, including PFOA. The landfill is strongly suspected to be releasing PFAS from local industry sources over its operational life. TRC will perform sampling of groundwater monitoring wells and water and sediment from a nearby pond and small drainage ditches for various constituents including PFAS. TRC will also perform full validation of all analytical data generated during this program. Ultimately, information generated will be reviewed by the NYSDOH to determine if site contamination presents public health exposure concerns and to also determine if the landfill leachate is contaminating the nearby pond.
