More than 350 gallons of home heating oil pumped into Mass. family’s basement. Now they can’t live there. How much this disastrous mistake could cost

It wasn’t a package gone astray. It was 385 gallons of home-heating oil, mistakenly pumped straight into the Nguyens’ basement by a Fawcett Energy driver who showed up not just at the wrong house, but the wrong city.

The delivery was meant for 48 Linwood Street in Malden. Instead, the truck was parked outside 48 Linwood Street in Medford, where Nguyen lives.

"The oil delivery driver pulled up to the wrong address, put 385 gallons of oil into a basement with no oil tank," Medford Deputy Fire Chief Nicholas Davis told CBS News Boston.

Now the Nguyen family has been evacuated and early estimates suggest cleanup and repairs could run as high as $200,000.

A spill that won’t stay contained

Fire officials say the oil didn’t just pool. It spread across the entire basement floor, raising fears it could seep into the ground beneath the home. Nguyen’s home still has an exterior oil fill connection in the same spot where delivery hoses attach, but he removed his oil tank five years ago after switching to gas heat.

Davis noted that a standard home delivery typically ranges from 150 to 250 gallons.

"Normally when you are filling up an oil tank, once it starts to get full you hear the whistle and that keys the driver to shut down the oil. But there is no whistle because there is no tank,” Davis said.

Oil spills like this are unusual, but the ripple effects are anything but small. Beyond the chaos of cleanup, contamination can drag down property values for years.

After the 2010 Deepwater Horizon explosion, the largest offshore oil spill in U.S. history, a 2019 Journal of Housing Economics study found home prices in the region fell 4% to 8%, with losses lasting through 2015. The researchers estimated the disaster wiped out $3.8 billion to $5 billion in housing value.

Massachusetts isn’t new to these risks. More than 650,000 homes in the state still rely on oil heat, yet only 7% of those households carry the specialized insurance that would help cover cleanup costs if a tank leaks or oil spills into the ground.

A small rider that protects you from a massive bill

For Nguyen, the timing couldn’t be worse. He was preparing to host 20 people for Thanksgiving, a holiday now overshadowed by hazardous fumes, cleanup crews and a question mark hanging over who is footing the bill. And cleanup is only the beginning.

Once a family is displaced, the real costs start piling up fast, from hotel stays to scrambling for longer-term housing.

In Massachusetts, where the average rent sits around $2,900, about 45% higher than the national average, even a short-term move can feel financially crushing. For a family of six like the Nguyens, the price tag only climbs. A three-bedroom apartment in the state now averages $3,400 a month, according to Zillow.

Kevin Hoag, the president of CommTank, which specializes in tank installations, removals and maintenance, says there’s no quick fix.
