Treatment of PFAS Chemicals in Water

On Tuesday Oct 8, 2019 Ryan Sullivan, VP of Service and O&M for Envirogen Technologies, presented at the New Jersey Water Environment Association (NJWEA) Fall Technology Transfer Seminar in Eatontown, NJ on the topic of treating for Per- and polyfluoroalkyl substances (PFAS) in water.
The presentation began with a review of how PFAS chemicals have entered groundwater, the health threats they pose when consumed in drinking water, and the current regulatory environment. He went on to discuss best available treatment technologies and presented a case study of a groundwater remediation project where Envirogen met or exceeded the effluent permit limits for an array of PFAS chemicals. Envirogen not only designed and built a Construction Contact Water Treatment Plant but also provided comprehensive operation and maintenance of the temporary system throughout the project.
Key to the project’s success was testing and identification of the best performing granular activated carbon type, and predictively determining optimum carbon changeout frequency to prevent effluent violations of PFAS substances included on the discharge permit.
Envirogen, already established for 30 years as an expert in groundwater remediation projects, furthered their reputation by quickly establishing success in the newly emerging area of PFAS treatment. As states continue to drive the establishment of regulatory limits for PFAS, Envirogen is poised to provide effective systems and offer onsite system operations and maintenance, if desired.

The NJWEA serves a critical role in the state of New Jersey. According to their website, “today the NJWEA and its members serve as leaders in the effort to preserve water quality, remediate historically contaminated sites, help industry to manage their water processes in a sustainable manner and educate the public on water quality issues”
