Managing Efforts to Mitigate PFAS Impacts

MJ is managing all aspects of this project, both on and off the airport property. This on-going project involves the investigation and mitigation measures necessary to rectify the historic release of Aqueous Film Forming Foam (AFFF) containing per-and polyfluoroalkyl substances (PFAS) into the soil, drinking water, and groundwater. The releases occurred as part of the FAA-required fire suppression testing and training, as well as emergency responses.

MJ’s professionals worked closely with Nantucket Memorial Airport and a specialized subconsultant (License Site Professional) to quickly develop a plan of action based upon the locations and volume of the AFFF release locations, direction of groundwater flow and location of potential receptors. A summary of services follows:

  • To assist and manage the work conducted by the Licensed Site Professional (LSP) and specialized subconsultants and contractors as defined by the Massachusetts Contingency Plan (MCP),
  • To manage and lead the public outreach and transparency with community at-large that includes a project-specific website ( and to host public meetings and individual meetings with impacted homeowners (77 private water wells sampled; 65 homes provided bottled water);
  • To develop a plan of action based upon historic use of PFAS-containing AFFF and the locations of its release,
  • To determine the proximity of potential receptors based upon groundwater flow direction, release locations, and hydrogeology,
  • To review the design of Point-of-Entry Treatment (POET) systems for individual residences,
  • To act as liaison with airport management, agencies, local officials, public and media,
  • To identify funding sources to off-set the cost of investigation and remediation measures,
  • To prepare and secure regulatory permitting from jurisdictional agencies,
  • To design, permit, and provide construction administration for a two-mile town water main extension to service impacted residences
  • 19 buildings connected to new water main, and,
  • To effectively work with legal counsel to ensure compliance at all levels of regulatory jurisdiction, access agreements, and public outreach.
