POLLUTION REPORT

Subject: 

The Wells G & H Superfund Site covers approximately 330 acres in Woburn, Middlesex County, Massachusetts.  The Site includes the aquifer and land area located within the zone of contribution to the City of Woburn’s two municipal drinking water wells known as Wells G & H.  The Olympia Property is one of the five primary source areas of contamination within the Federal Superfund Site.

At a former drum disposal area at the Site, PCB-contaminated surface soils posed a direct contact threat and TCE-contaminated subsurface soils are acting as a continuing source of ground water contamination.  See previous polreps for additional background information.

The Olympia Nominee Trust (Olympia) has been identified as a potentially responsible party (PRP) as the owner of the site.  Olympia is performing the removal action under an Administrative Order on Consent (AOC) issued by EPA.  Removal activities completed by Olympia during previous reporting periods include excavation and off-site disposal of the PCB-contaminated surface soils, sampling activities to further characterize the Site, and initiation of cleanup activities relative to the TCE-contaminated subsurface soils.

During this reporting period, Olympia completed site preparation activities, made necessary improvements to the dirt access road, mobilized a crane, and began installing sheet piling to isolate the in situ treatment cell area.

Planned removal activities include (1) installation of injection wells, trenches, and the permanganate delivery system; (2) operation of the in situ treatment system; and (3) monitoring to ensure compliance with cleanup standards established in the Record of Decision (ROD).

Olympia plans to complete the sheet piling installation within the next 2-3 weeks.
