A small piece of the failed coupling blamed for a water main break that left nearly 2 million Massachusetts residents under a boil water order last month has been recovered.
The Boston Globe reports that an 11-by-12-inch sealing plate was found Wednesday during grading work between the Charles River and the 10-foot wide pipe in Weston.
The lightweight plate is one of two pieces used to secure the coupling around the pipe that supplies water to greater Boston.
The coupling could hold clues as to what caused the May 1 rupture that forced people to boil their tap water before using.
A Massachusetts Water Resources Authority spokeswoman says the search, which has cost $137,000, has been suspended until next week.
