City of Westfield PFAS System Completion

Our Mechanical Construction Division recently completed a project in Westfield, MA due to the prevalence of per- and polyfluoroalkyl substances – PFAS and PFOA. The city’s efforts were honored by Water and Wastes Digest as a 2019 Top Project Winner. PFAS and PFOA include a group of man-made chemicals that do not readily break down in either the environment or the human body and, therefore, can build up over time. There is human and experimental lab evidence that exposure to PFAS can lead to adverse human health effects. The construction of a Granular Activated Carbon Water (GAC) Treatment Facility will effectively reduce PFAS levels to five parts per trillion or less, well below the health advisory levels of 70 parts per trillion. As we continue to learn about long-term health risks associated with PFAS, it is expected that this GAC facility will be the first of many in the state of MA and nationwide.
