Abstract:

The biological treatability of the contaminated soils at a former coating and resins facility was investigated in the laboratory using small scale composting reactors. The soil treatment system was designed to simulate full-scale operation of a biological treatment facility and included weekly moisture additions and tilling/turning. The results show that these soils were highly contaminated with total volatile organic constituents (TVOC) at a level of approximately 6,000 ppm. The primary constituents measured were F003 and F005 wastes and chloroform. The TVOC concentrations were reduced to 350 ppm (94 percent reduction) over a 56 day period with minimum amendments and minimum handling and tilling. Most importantly, leachate (as measured in the TWC leach test) TVOC concentrations were reduced from 253 to 11 ppm. Most of the individual VOCs were present at non-detectable levels in the leachate and all were below 1 ppm.
