Superfund Record of Decision (EPA Region 1): Norwood PCB's, Norwood, MA. (First Remedial Action), September 1989

摘要

The 26-acre Norwood PCBs site consists of several industrial and commercial properties, parking areas, and vacant lots in Norwood, Norfolk County, Massachusetts. Site contamination originated from disposal practices of previous businesses, primarily electrical equipment manufacturing, that operated from the building now owned by Grant Gear Realty Trust. In April 1983 the State responded to a citizen report of previous industrial waste dumping at the site and took surficial soil and sediment samples which confirmed PCB contamination. In June 1983 EPA moved 500 tons of PCB-contaminated soil from the office park complex and Grant Gear properties and disposed of it offsite. The State implemented an Interim Remedial Measure in 1986 to limit access to areas with high surface contamination on the Grant Gear property by constructing a 1.5-acre cap. The primary contaminants of concern affecting soil, sediment, ground water, and building surfaces are VOCs including TCE and PCE; other organics including PCBs, PAHs, and phenols; and metals.
