Groundwater Remediation Program

The Orange Line South West Corridor Tunnel and South Cove Tunnel interface located next to the Back Bay/ South End Area of the City of Boston has been identified as an area that is affected by groundwater infiltration.

The MBTA has been responsive to groundwater concerns along the Southwest Corridor, near the Back Bay Station. Part of this response was the creation of the MBTA Groundwater Action Committee, which is comprised of representatives from the MBTA, BWSC, the City of Boston, The Boston Groundwater Trust and the Boston Groundwater Emergency Task Force.
