During the Woburn City Council meeting on February 6, 2024, officials provided a crucial update on the ongoing situation regarding PFAS (per- and polyfluoroalkyl substances) contamination in the city's water supply. The quarterly report for the fourth quarter of 2023 revealed that the average PFAS levels were measured at 21 parts per trillion (ppt), slightly above the Massachusetts Department of Environmental Protection (MassDEP) standard of 20 ppt. This information will be communicated to residents through a mailing expected to be delivered later this week.

Despite the slight exceedance, city officials reassured the public that the situation is under control. Since testing began in 2019, the long-term average PFAS level has remained around 0.9 ppt, with January 2024 showing a significant drop to 13.5 ppt. The city is actively monitoring the water quality and is in the process of designing a new treatment plant aimed at addressing PFAS levels at Horn Pond, which is expected to meet both state and forthcoming federal standards.

The meeting also highlighted the anticipated federal regulations on PFAS, which are expected to be finalized soon. The Environmental Protection Agency (EPA) is proposing a limit of 4 ppt for two specific PFAS compounds, PFOA and PFOS, which are currently averaging 7 and 8 ppt at Horn Pond. The city is preparing to implement treatment solutions that will comply with these new federal standards.

In addition to the PFAS update, discussions included the city's ongoing efforts to secure funding for the new treatment facility, which is projected to exceed $10 million. The bidding process for construction is set to begin by the end of February, with the goal of starting construction by mid-2024 and completing it by early 2026.

Overall, the meeting underscored the city's commitment to addressing water quality issues and ensuring the safety of its residents. As the situation evolves, city officials remain dedicated to keeping the community informed and engaged in the ongoing efforts to manage PFAS contamination.
