Site Meeting on Building and Groundwater NTCRAs

On 31 AUG 2016, representatives from EPA, MassDEP and de maximis met with members of the 2229 Main Street Committee, CREW, and Green Acton, as well as representatives of the Town of Acton and Acton Water District to present an update on the Building and Groundwater Non-Time-Critical Removal Actions (NTCRAs).

The Groundwater NTCRA AOC became effective in July 2016. Between October 2015 and July 2016, significant further delineation of the extent of groundwater contamination was completed. The next steps under the Groundwater NTCRA will be installation of pumping and monitoring wells, hydraulic testing, and design and construction of an ex-situ groundwater treatment system.
