NPL Site Narrative for Silresim Chemical Corp.

Lowell, Massachusetts

Federal Register Notice:  September 08, 1983

Conditions at listing (July 1982): The Silresim Chemical Corp. Site covers 5 acres in an industrial area 1 mile south of the central business district of Lowell, Massachusetts, and 0.3 mile from several residential areas. Starting in 1971, Silresim began reclaiming (under a State permit) a variety of chemical wastes, waste oil, solvents, and sludges containing heavy metals. In 1977, Silresim declared bankruptcy and abandoned the site, leaving behind 30,000 decaying drums and several large storage tanks. When the owner abandoned the site, the State undertook a $2.2 million cleanup of the drums and tanks.

Ground water flows generally to the northwest toward Meadow Brook, which drains into the Merrimack River, the source of water for Lawrence. Surface water containing volatile organic compounds, pesticides,and PCBs drains from the site onto two or possibly three adjacent properties. Soil is similarly contaminated. A noticeable odor is present and is aggravated by hot or humid weather.

Status (July 1983): In April 1983, EPA completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site. EPA is upgrading the fence which surrounds the site and undertaking a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action. During the summer and fall of 1983, EPA is scheduled to demolish the buildings on-site and temporarily encapsulate the site to prevent contaminants from migrating off-site. Negotiations with parties potentially responsible for wastes associated with the site will also be undertaken during the summer.
