Update: The stuff included asbestos.
The Boston Fire Department reports firefighters responded to 99 Summer St., near Kingston Street, around 5:30 a.m. after "e steam leak earlier sprayed unknown debris in the area."
Veolia crews were called in both to fix the leak and determine what the white stuff was. The Globe reports the substance tested negative for anything dangerous, but that Summer will be shut to Surface Road overnight to allow for additional testing.
