BOSTON—Massachusetts lawmakers are holding a hearing on the recent water main breach that left nearly 2 million people under an order to boil their water.
The committees on post audit and oversight and environment resources plan to hear testimony Wednesday and Thursday at the Statehouse from officials seeking the cause of the blowout.
Investigators at the Massachusetts Water Resources Authority have yet to locate what Gov. Deval Patrick has described as a key piece of evidence: a one-ton metal coupling that joins sections of the 10-foot pipe.
The coupling is being eyed as the chief culprit in the blowout. Investigators have already used state police dive teams, metal detectors and ground-penetrating radar to search for the coupling.
