The Southborough Special Town Meeting held on May 10, 2025, focused on critical environmental monitoring issues related to the town's landfill and proposed construction projects. A significant point of discussion was the status of gas probes used for post-closure monitoring of the landfill. It was reported that 12 out of 20 gas probes were missing during the last monitoring session.

The meeting highlighted a new design for the area in front of the school, which includes three proposed monitoring wells. Two existing wells, MW3S and MW3D, were found to contain reportable levels of dissolved oxinic, barium, and 1.4 dioxins. Additionally, another well, MW2, located near the school, has standing water, raising further concerns.

The presentation also noted the presence of chlorine and other contaminants at levels exceeding safety requirements at the landfill site. While detailed questions were deferred to the Department of Public Works (DPW) superintendent and the Board of Health, the urgency of addressing these environmental issues was emphasized.

In a related decision, the Board of Selectmen approved the expenditure of $10,000 from aqua funds for NEAR soil testing around the proposed new building site, with a unanimous vote of 4 to 0. This testing is crucial for ensuring the safety of the area, particularly for children playing on nearby fields.

The discussions at the meeting underscored the town's commitment to monitoring environmental safety and addressing potential hazards associated with the landfill and new developments.
