The Department of Energy and Environmental Protection responded to Montville Saturday after hundreds of gallons of diesel fuel leaked into wetlands.
Dispatchers confirmed that fire crews responded to wetlands near the Stony Brook Reservoir around 9:30 a.m. DEEP was also called to respond.
DEEP officials confirmed that about 600 gallons of fuel leaked from a back-up generator system at a treatment plant that belongs to Norwich Water. Officials said some of the fuel pooled up in the low wetlands and the rest is being cleaned out through soil evacuation.
DEEP officials said there is no threat to drinking water supplies.
Contractors remain on scene cleaning up.
