BOSTON – BOSTON (AP) — A one-ton metal coupling blamed for a water main break that left nearly 2 million Massachusetts residents under a boil-water order last month has yet to be found, and searchers are running out of options for finding it.
Massachusetts Water Resources Authority spokeswoman Ria Convery says workers have excavated as deep as they safely can in the area around the leak, but have come up empty.
Investigators have used state police dive teams, metal detectors and ground penetrating radar. They've also dredged soil that was blown into the river when the pipe gave way.
Officials say there's a remote chance the coupling could have been buried under the concrete poured after the pipe was repaired.
The coupling could hold clues as to what caused the accident.
