GOFFSTOWN — Mountain Road has been reopened and 100 percent of the contaminated soil removed just short of two weeks after an Irving Oil fuel tanker rolled over and leaked over 1,000 gallons of heating oil near a brook that runs into the town’s reservoir.
On Thursday, the Department of Public Works put out a statement confirming that the route was open to motorists following roughly 12 days of extensive cleanup by hazardous materials contractors, who DPW officials say removed 750 tons of contaminated soil from the site of the rollover.
The rollover took place at approximately 7:30 a.m. on Nov. 25, when the tanker veered off the road on an icy stretch of Mountain Road along Whittle Brook during a winter storm.
The driver was uninjured in the accident.
DPW stated that all of the contaminated material was excavated by John Neville Excavating, contained in plastic tarps, moved into roll-off containers and hauled to an off-site location.
The contaminated soil will be recycled by NRC.
In addition to the excavation and removal of the contaminated material, DPW officials say crews rebuilt the section of road in compacted lifts, dug up and replaced drainage pipes that were contaminated by fuel and repaved the roadway.
“The contaminated material is (100 percent) removed and all other work is substantially complete,” said DPW Director Megan Theriault.
While the roadway is now open, Theriault said there may still be one lane alternating while workers rebuild a head wall.
The crews will also begin installation of six monitoring wells, which the Department of Environmental Services mandates in order to observe and verify contaminant levels in the neighboring waterways.
DPW was uncertain of the total cost that the town has spent on emergency response and cleanup efforts, but state regulations make clear that Irving Oil will be responsible for reimbursing Goffstown for costs associated with removing oil and restoration of the spill site and surrounding environment.
