Merrimack Valley Gas Explosions: Three Years Later

Sept. 13, 2018, is a day that residents of the Merrimack Valley will never forget. Explosions and fires rocked the cities of Lawrence, Andover and North Andover, killed one man and seriously injured more than a dozen others.

Leonel Rondon, 18, died when a chimney fell on top of his parked car. About 8,000 people were displaced after more than 100 homes burned.

The disaster was pinned on utility company Columbia Gas and its mismanagement of underground natural gas lines in the Merrimack Valley. In 2020, Columbia lost a lawsuit launched by Massachusetts Attorney General Maura Healey, forcing the utility company to pay more than $56 million in fines and promise to never operate in the Bay State again.

Now the largest fine ever issued under the Federal Pipeline Safety Act, Columbia Gas also settled a class action lawsuit for $143 million brought by victims of the Merrimack Valley gas explosions. While 11,000 people received compensation, many others are still waiting for their checks.
