Remediation of the Former Medfield State Hospital
Background:
The former Medfield State Hospital (MSH) site is located in Medfield, MA along the Charles River. The Division of Capital Asset Management (DCAM) maintains control of this approximately 225 acre property with its buildings, and plans to sell a large portion to private developers. The Commonwealth of Massachusetts also owns approximately 225 acres to the west, and approximately 110 acres to the north of the MSH facility. Both of these areas were originally part of the hospital property, but are currently under the care and control of the Massachusetts Department of Conservation and Recreation (MassDCR).

The MSH was used as a psychiatric treatment facility from 1896 until 2003, when it closed. It was a self-sufficient facility that included residential facilities, farm fields, a dairy facility, machine and carpentry shops, a laundry facility, and a power plant. Unfortunately, historical waste management practices were not up to the standards of today, and the MSH site currently includes 5 areas of concern due to high contamination levels (Shown in the figure below: Clay Containment Area, Construction Debris Area (C&D Area), Power Plant Area, Special Project Designation (SPD) Area, and the Salvage Yard Area). Under the Massachusetts Contingency Plan (MCP) , DCAM is currently evaluating the extent and nature of the contamination at each of these sites and will be responsible for the remediation.

CRWA has been closely tracking and has been involved in DCAM's proposed cleanup plans for MSH. Of particular concern to CRWA is the cleanup of the Construction and Demolition Area (C&D Area); the area directly bordering the Charles River. The site is contaminated with coal ash, oil and hazardous materials , metals, asbestos, polycyclic aromatic hydrocarbons, and volatile organic compounds (i.e. tetrachloroethylene - PCE). CRWA objects to DCAM's plan to cap rather than to excavate and restore this abandoned dump area adjacent to the river, as well as contaminated sediment in the river. We are particularly concerned about contamination continuing to migrate into the Charles, and the proposed use of riprap armoring along the banks, which capping would require. Restoration should include bank restoration, the removal of the contaminated sediments from the river, and excavation of the contaminated fill with the C&D Area within the Riverfront Area.
On August 26, 2011, the Medfield Conservation Commission approved DCAM's Notice of Intent (NOI), by issuing an Order of Conditions (OOC). CRWA appealed the Conservation Commission's OOC by requesting a Superseding Order from MassDEP. The Trustees of Reservations (TTOR), which owns the Rocky Narrows property directly across the Charles River from the MSH site, appealled the OOC along with CRWA. Both CRWA and TTOR appealed becase the Conservation Commission's OOC fails to comply with the Massachusetts Wetlands Protection Act; numerous performance standards were not met (See Request for Superseding Order below), the OOC would permit work having significant environmental effects, and DCAM failed to prove there were no practical alternatives to the work proposed.
MassDEP has granted a stay on the request for a Superceding OOC, allowing DCAM time to engage stakeholders, revisit other alternatives, and formulate a more suitable final remedy for everyone involved. Working towards this goal, CRWA attended two meetings this January (2012) at the Medfield Town House held by DCAM, to discuss the modification to the Immediate Response Action (IRA) Plan, potential remediation strategies, as well as any outstanding questions the town or other stakeholders had about the project. CRWA continues to push for a long-term, ecologically sustainable solution to the remediation, and in addition to being actively involved in these stakeholder meetings, CRWA continues to work for an environmentally healthy solution through submission of comments to project plans (such as the IRA modification below).
Recent CRWA Actions:
The Division of Capital Asset Management (DCAM) recently evaluated various remedies and selected mechanical dredging of contaminated river sedimetns and a partial removal and cover of the 3.2 acre dump with bank biostabilization. CRWA disagrees with DCAM's proposed rememdy, both in terms of short term environmental effects (excessive turbidity and downstream migration of contaminated sediment during dredging), and long-term reliability (DCAM’s approach calls for contaminated fill to remain in contact with the water table presenting potential future migration pathways). CRWA is advocating for changes, including blocking off the river area during dredging with a coffer dam, to ensure precise removal of the contamination, and to eliminate turbidity and the risk of spreading the contamination. For the dump, CRWA recommends that DCAM at an absolute minimum remove the hazardous material in contact with groundwater to prevent its migration to the river. Read the comment letter.
