FITZWILLIAM, N.H. (MyKeeneNow) Emergency crews responded to Laurel Lake in Fitzwilliam Saturday after a truck sank into the water, releasing an estimated 30 gallons of diesel fuel and prompting a multi-agency environmental response.

The Fitzwilliam Fire Department was dispatched at approximately 11 a.m. Oct. 10 after receiving a report of the sinking vehicle, according to a news release. Firefighters arriving at the scene discovered an active fuel leak and established incident command under Fire Capt. Keith Mattson.

Keene firefighters were called in to help contain the spill, bringing a boat and utility trailer to the scene, the release said. Keene Fire Deputy Chief Rogowski and Lt. McLean assumed operational command of the response, while the Winchendon, Massachusetts, Fire Department sent a dive team and shore support to assist with the vehicle’s recovery.

Crews deployed floating containment barriers to limit the spread of diesel across the lake. A solid containment boom launched from the Keene Fire Department boat was used to isolate the spill, with additional barriers positioned to protect downstream water outflows.

The New Hampshire Department of Environmental Services (NHDES) provided technical assistance with the environmental response and estimated the amount of diesel released at approximately 30 gallons.

The Winchendon dive team secured the submerged truck, allowing J&J Truck Service and Towing to remove it from the lake.

Once the vehicle was recovered and initial containment measures were completed, Mattson transferred incident command to NHDES, which will oversee further environmental assessment and remediation.

Personnel from the Troy Fire Department, Fitzwilliam Police Department and Troy Police Department also responded to assist with staffing and traffic control. Fitzwilliam-Troy Ambulance remained at the scene to provide emergency medical services standby.

The Fitzwilliam Fire Department thanked the responding agencies and mutual-aid partners for their assistance.

NHDES is handling the continuing environmental assessment and cleanup. The fire department directed requests for additional information to its agency.
