  • Site Description
    Stage of Clean-up: Construction Underway

    Conditions at listing (October l981): The Industri-Plex 128 Site covers 250 acres in North Woburn, Massachusetts. Between about l953 and l981, Merrimac Chemical Co. and its successor, Monsanto Co., manufactured insecticides, explosives, acids, and other chemicals at the site. In the late l960s, much of the site was acquired by the Mark Phillip Trust for industrial development. Excavation in the l970s uncovered and mixed 130 years' accumulation of industrial by-products and wastes. Many of the pits, piles, and lagoons are continuously leaching toxic metals into the environment. As excavation progressed, pockets of buried animal hides from glue manufacturing were exposed to the air, causing odors. In June l979, the Army Corps of Engineers and the State issued a cease and desist order to the Trustee relative to the placing of dredged or fill material into the wetlands on the site. Both the Corps and the State entered into Consent Decrees requiring the defendant to deal with the hazardous waste problems at the site. The defendant did not. This site was first listed under the name "Mark Phillip Trust." Status (July l983): Shortly after the site was listed, Stauffer Chemical Corp. came forward to discuss its role in cleanup of this site. Extensive discussions resulted in a Consent Order, which outlines a two-phase investigation leading to a long-term solution. Stauffer has completed the field portion of Phase I. Phase II, a feasibility study, is scheduled to begin in mid-l983.  More...

    Sources of Contamination:

    • Lagoon disposal
    • Waste pile

  • Threats and Contaminants
    The groundwater is contaminated with VOLATILE ORGANIC COMPOUNDS (VOCS) including BENZENE and TOLUENE, and ARSENIC. The soil is contaminated with HEAVY METALS including ARSENIC, CHROMIUM, and LEAD. Also, a pervasive "rotten egg" odor has been caused by HYDROGEN SULFIDE gas generated by the decay of the buried animal hides from glue manufacturing wastes. People who accidentally ingest or come into contact with contaminants may be at risk. However, since the site is mostly vacant now, with plans for industrial and commercial use, the potential exposure most likely is limited to trespassers and workers on the site during future construction. The contaminated groundwater has the potential to migrate towards two Woburn municipal drinking wells, which are currently closed.  More...
