| Abstract |
The 4.5-acre Silresim Chemical site is a former chemical waste reclamation facility in Lowell, Massachusetts. From 1971 to 1977, Silresim Chemical Corporation (SCC) used the site for a chemical waste reclamation facility. State investigations revealed evidence of numerous spills, leakage of drums, discharges to nearby sewers, and run-off to adjacent property. A number of EPA and State investigations revealed contamination of soil and ground water. From 1978 to 1982, the State constructed a fence, removed liquid waste in onsite drums and tanks, and constructed berms and absorbent-filled trenches. From 1983 to 1984, EPA removed all onsite structures, extended the fence, and placed a clay cap over the site. The Record of Decision (ROD) addresses both onsite and offsite soil and ground water contamination. The primary contaminants of concern affecting the soil and ground water are VOCs including benzene, TCE, toluene, and xylenes; other organics including dioxin, PAHs, PCBs, and phenols; and metals including arsenic, chromium, and lead. The selected remedial action for the site is included. |
