Workers with the Massachusetts Water Resources Authority are investigating an apparent underground water leak near the site of May’s massive water main break.
A spokeswoman for the agency said a small amount of water is bubbling up and crews are on the scene trying to determine exactly where it’s coming from and how to fix it.
No service interruptions have been reported.
The site is about 220 feet downstream from the location of May’s water main break that left nearly 2 million Massachusetts residents in 30 communities including Boston under a boil water order.
Investigators looking into the cause of the May break have focused on a coupling that was designed to hold together two section of a 10-foot pipe.
Workers last month recovered a section of the coupling.
