Description:
The Toronto Harbour Commissioners (THC) have developed a soil treatment train designed to treat inorganic and organic contaminants in soils. THC has conducted a large-scale demonstration of these technologies in an attempt to establish that contaminated soils at the Toronto Port Industrial District can be treated to attain contaminant levels below the THC Criteria Levels for Industrial Soils. without utilizing incineration processes. The THC’s treatment train evaluated during this SlTE Demonstration consists of three soil remediation technologies: an
attrition soil washing technology, inorganic removal by chelation, and a chemical and biological treatment to reduce organic contaminants. The overall process sequence is determined by the specific contaminants in the soil to be treated. Sampling, data collection and analysis as part of the THC demonstration were conducted under the SITE program utilizing
appropriate analytical procedures as specified in SW846 to provide a consistent basis for comparing these technologies to other technologies evaluated under the SITE program. Based on the results of the SITE demonstration project at the THC Soil Recycling Demonstration Project, Toronto, Ontario, Canada and information concerning the overall THC project, several conclusions can be drawn.
* The primary developer’s claim that the gravel, sand, and fine soil products will meet the THC criteria for reuse as fill material at industrial/ commercial sites was achieved by the gravel and sand products, representing 79.6 percent of products. The fine soil representing 18.8 percent of the products exhibits significant reduction in PAH compounds as a result of biological processing but did not meet the criteria level of 2.4 mg/kg for benzo(a)pyrene.
* The attrition soil wash plant produced a gravel (
