Footage showed the hangar where the helicopter was kept being filled with chemical foam as alarms blared, with the system accidentally releasing hundreds of gallons of Concentrated Aqueous Film-Forming Foam (AFFF), Force.net said. reportAFFF is used on fires that start with flammable liquids, such as jet fuel. Vermont Department of Public Health report.

“It looked like a white bubble bath,” Water Quality Control Supervisor Bob Fisher said, according to the media. The National Guard estimates that the accident dumped about 150 gallons of foam into South Burlington's sewer system, according to the media.

“We knew the risk to the environment was significant, and we wanted to avoid the possibility of a spill, whether it was intentional or accidental,” said Col. Jacob Roy, the Vermont National Guard's construction and facilities management officer. The Vermont National Guard worked with other agencies to manage and contain the spill, according to Force Net.

According to Vermont Public, National Guard contractors are cleaning and inspecting the facility itself, the sewer lines, the pumping station and the wastewater treatment plant daily. They've also tested the water in the nearby Winooski River for contamination, the outlet reported. “Understanding that a normal day's flow rate in the Winooski River is about 5,000 gallons per second is a good way to put things in perspective,” Matt Chapman, director of the Waste Management and Prevention Division for the Vermont Department of Environmental Conservation, told the outlet.
