LAWRENCE, Mass. (WWLP) – Investigators have uncovered a preliminary cause for Thursday’s gas leak in Lawrence. They say a water contractor made an error, causing the leak.
A joint statement from the Department of Public Utilities, Columbia Gas and the City of Lawrence says a city contractor “Inadvertently closed a gas valve, puncturing an active gas main.”
The valve in question was not up to DPU standards. Columbia Gas says it will check 45 valves to ensure they are up to code.
Governor Charlie Baker said, “They still have a way to go with me. That’s why DPU is going to have such a big presence here over the course of the next few days.”
Governor Baker and Lawrence mayor Dan Rivera did applaud Columbia’s quick work Friday.
Officials announced Saturday that evacuated residents could return home.
