Waste Site Cleanup & Reuse in New England
The Hilton Chrome site is home to a former metal finishing/electroplating plant that operated until Nov. 2011. After complaints led to an inspection by the Mass. Dept. of Environmental Protection, the Lawrence building inspector shut down operations indefinitely. About 45 open polypropylene plating, rinsing and waste vats and tanks were found holding hundreds of gallons of fluids. Several dozen drums were found holding labeled chemicals, wastes and unknown fluids. Several areas in the building were structurally unsound. An inventory of materials included hydrochloric, nitric and sulfuric acid, 50% sodium hydroxide, acid copper solution, granular copper cyanide and sodium cyanide.
EPA cleanup crews and contractors began the cleanup May 9, 2012. Over the next months, approximately 65 drums and containers, 52 250-gallon totes; seven one cubic-yard box; 14 50-gallon bags of cardboard, 7 50-gallon bags of bottles and plastic, one 50-gallon bag of cans; and 60 55-gallon drums were taken off site for disposal. Debris, sludge and concrete blocks from the waste water treatment area as well as fluorescent bulbs and suspected PCB-containing light ballasts were also taken off site for disposal. A contractor hired by the Greater Lawrence Sewer District did a robotic scope of an underground cement pipe, and steel plates were subsequently installed. Approximately 1,500 - 2,000 cubic yards of contaminated soil excavated from the southeast side of the property were disposed of and the area was backfilled. About 4,900 gallons of groundwater was pumped from the excavation pit into a holding tank and then discharged to the interceptor on property next door. Holes in the building floor were patched, the excavated pit was lined and backfilled. Another 1,000 cubic yards of contaminated soil excavated from the northeast side of the property was disposed of offsite and the area backfilled. A permanent fence was installed next to a portion of the northeast wall and roof that collapsed Nov. 15. Openings in the building were boarded up and a permanent fence was installed around the property's perimeter. Workers left the site Dec. 18, 2012.
