Wayland board briefed on two new contamination plumes near Town Center

WAYLAND -- April 24, 2017, Wayland board learns two new chlorinated solvent plumes at Town Center came from off-site sources. Licensed site professional Ben Gould told the Select Board on April 24 that Raytheon's consultant identified two additional plumes during detailed sampling and filed a downgradient property status report shifting responsibility off Raytheon; DEP is expected to issue formal requests for information to eight potentially responsible properties, including Wayland Town Cleaners, two gas stations, CVS and the post office. Gould called the dry cleaner the property that "jumps out" and said the affected groundwater, 60 to 80 feet down, lies within the Zone 2 aquifer feeding the Baldwin Pond wells, "an area of high concern," though not an immediate threat to drinking water. The board separately voted 5-0 to approve a $52,291 payment in lieu of betterment for 820 gallons per day of sewer capacity at 5 Concord Road, the future library site, and Town Administrator Nan Balmer disclosed an $86,377 deficit on the library drainage project that will go to the Finance Committee for a transfer.
