Paul Rosala, the county’s assets and infrastructure manager, said the county owns the roughly five‑acre site where aqueous film‑forming foam (AFFF) was used during training over several decades and that PFAS from those exercises contaminated soils and groundwater and has impacted municipal drinking wells down gradient. Rosala said the county does not have records of the foam volumes used because the site was used by multiple local fire departments and the county “did not provide foam.”

GZA Principal John Paquin said the county and consultants have compiled decades of historical data, installed 16 additional multi‑level monitoring wells, and analyzed groundwater flow to distinguish the fire‑training plume from other local PFAS sources, including airport and wastewater‑treatment‑plant releases. Paquin described the planned remedy: a full‑scale permeable reactive barrier (PRB) consisting of injected activated carbon placed along the downgradient inside of the county property to sorb PFAS and limit further off‑site migration. Paquin said a small pilot PRB installed late last year produced strong early results, including a drop from measurable concentrations at the downgradient monitoring points to nondetectable levels in the areas tested.

Work schedule and costs: Paquin said the full‑scale PRB injection is scheduled to begin the week of July 14 and is expected to take roughly three months to install. The county has removed more than 200 tons of hot‑spot soil and paved (capped) the site to reduce infiltration. The county currently operates a groundwater pump‑and‑treat system that draws impacted groundwater to a carbon treatment unit and then discharges treated water back to the aquifer; consultants said pump‑and‑treat is expensive and that the PRB is intended as a more efficient, passive approach to reduce long‑term migration and treatment costs.

Liability and funding: County staff said the county has an earlier settlement with Hyannis (Hyannis Water District) that obligates the county to share some operation and maintenance costs for affected wells; the county has also allocated ARPA funds and retained outside counsel and consultants for remediation and potential recovery actions. Staff said it has joined broader PFAS litigation efforts and is exploring state and federal grant opportunities to offset remediation costs but cautioned that quantifying liability and pursuing cost recovery will be complex.

Public health and technical limits: Delegates asked whether the injected carbon can be removed; Paquin said the PRB is created by injecting a carbon slurry that is not recoverable and that the approach is considered a medium‑term engineering control (current field data show efficacy over roughly a decade, though long‑term data are limited). Consultants and county staff said ongoing wellhead treatment at municipal systems will likely remain necessary as a polishing measure while downgradient concentrations decline.

Ending: County staff invited delegates to site visits and to a public update at the end of July; consultants expect to complete a Phase 2 comprehensive site assessment and ecological risk assessment by year‑end and to present updated monitoring results and modeling at future briefings.","mediaType","Video","parentTitle","July 2, 2025 Assembly of Delegates Regular Meeting","oneSentenceSummary","Barnstable County officials and consultant GZA briefed the Assembly of Delegates July 2 on PFAS contamination at the former municipal fire‑training facility in Hyannis and outlined plans to install a full‑scale permeable reactive barrier to limit migration toward municipal drinking wells.","taxTitle","Barnstable County, Massachusetts","taxId",12948,"location","headline","","shortSummary",{"_33":76,"_35":36,"_37":38,"_39":77,"_41":78,"_43":79,"_45":80,"_47":81,"_49":82,"_51":83,"_53":84,"_55":56,"_57":58,"_59":85,"_61":62,"_63":64,"_65":86,"_67":68,"_69":70,"_71":68,"_72":73,"_74":73},6180091,"Assembly Hears Public Concerns Over Cape Cod Commission Rule Requiring Certified Local Plans",1485,656000,2141000,"/Search/View?dp=1&key=5120880-d3f7e7200d9501d3c07743fa36c41407&start=656&end=2141","https://assets.pipeline.soar.com/5120880-d3f7e7200d9501d3c07743fa36c41407/thumbnail_656000.jpg","/articles/6180091/Barnstable-County/Massachusetts/Assembly-Hears-Public-Concerns-Over-Cape-Cod-Commission-Rule-Requiring-Certified-Local-Plans","https://secure.pipeline.soar.com/6180091-e1725179328a3dd0bb454079072a1c3e/orig.mp4?Expires=1775508833&Signature=i4gKBPsLAZuhrkHAp9nb2JghlB5M3CyRuN9SKF0jklC1KCZiTyYnm-DH2k1JArxwvRU0YDVwzufSXbc8ZgAQGd5oYXVw-c06UPILhBickI6m4xSFd5i2X5z87NwuYZxnWlCEBdV5swC99Ea5nTz3P9AxjLh7O3-cNn72djd2q9Ox83zNRem9H9d-sWmX4c7sCQgeGnv83BhyCEzk3V-gU63lcaZZa7lnoo-~vyYKzCG4ViHxjVGS2lX8kOyIaPhXE6C7g0Dn786AZp0NH9Z5-tbpD88nCmoaam8Hvak3ysUwzofGoB5FHx5WcI65-1dFEKvi8aAtiow56XEjEU66Dw__&Key-Pair-Id=KUT5TJCACFTXG","The Barnstable County Assembly of Delegates held a public hearing July 2 on proposed amendments to the Cape Cod Commission’s development-agreement regulations that clarify the long-standing requirement that a municipality have a certified local comprehensive plan (LCP) to enter a development agreement.

The amendments, staff said, are intended to provide clarity and streamline certification by referencing the regional policy plan construct established in 2018. Cape Cod Commission Executive Director Christy Senatori told delegates, \"It is not new that there's a need to have a local comprehensive plan to enter into a development agreement,\" and Commission counsel Jessica Walgus said the requirement \"has been in place since 02/2014\" and that the proposed language mainly provides additional clarity.

Why this matters: development agreements offer a local alternative to the Commission’s Development of Regional Impact (DRI) review for large, multi-use projects that can span many years. If a town lacks a current certified LCP, the town generally must use the DRI process rather than the streamlined development-agreement pathway, a restriction delegates said can have material timing and cost consequences for towns pursuing projects.

Delegates and town representatives pressed several practical concerns. Brewster Delegate Bridal said many towns face gaps between adopted plans and certification—LCPs run on 10-year cycles, and it is \"extremely common\" for an LCP to expire before a new one is certified, often creating a one-to-two year lag, the commission staff said. Senatori and Walgus pointed to a recently adopted streamlined local comprehensive plan regulation and technical assistance the commission offers; they noted four towns—Bourne, Sandwich, Provincetown and Truro—had used those streamlined rules to obtain LCP certification.

Multiple delegates requested additional time to review the ordinance and consult town staff. Counsel reminded the assembly that the Cape Cod Commission Act gives the assembly a statutory window to act after formal receipt; delegates asked staff to determine when that 60-day period begins so members would know their voting deadline.

No vote was taken July 2. Senatori and Walgus said the proposed regulation had been through commission-level public process and committee review; they encouraged delegates to consult their town representatives, and several delegates said they would do so before the ordinance returns for a decision.

Ending: The hearing concluded with the assembly noting the next formal vote would occur after the clerk and counsel confirm the statutory receipt date and the assembly’s required timeline. Delegates were urged to consult municipal officials about local certification status before the ordinance returns to the agenda.","The Barnstable County Assembly of Delegates held a public hearing July 2 on proposed amendments to the Cape Cod Commission’s development-agreement regulations that clarify the long‑standing requirement that a municipality have a certified local comprehensive plan (LCP) to enter a development agreement.","actionData","errors"]
