TECHNOLOGY EVALUATION REPORT: TORONTO HARBOUR COMMISSIONERS (THC) SOIL RECYCLE TREATMENT TRAIN. Project Summary
Richardson*, T L. TECHNOLOGY EVALUATION REPORT: TORONTO HARBOUR COMMISSIONERS (THC) SOIL RECYCLE TREATMENT TRAIN. Project Summary. EPA/540/R-93/517 (NTIS 93-216067), 1993.
A demonstration of the Toronto Harbour Commissioners' (THC) Soil Recycle Treatment Train was performed under the Superfund Innovative Technology Evaluation (SITE) Program at a pilot plant facility in Toronto, Ontario, Canada. The Soil Recycle Treatment Train, which consists of soil washing, biological treatment, and metals chelation, is designed to treat inorganic and organic contaminants in soil. During the demonstration test, soil from a site that had been used for metals finishing and refinery and petroleum storage was processed in the pilot plant. The demonstration test results were mixed. The primary developer's claim to produce gravel and sand that met the THC target criteria for medium to fine soil suitable for industrial/commercial sites was achieved for the sand and gravel products. The fine soil from the biological treatment process exhibited anomalous oil and grease behavior and, although exhibiting a significant reduction in polynuclear aromatic hydrocarbon (PAH) compounds, did not meet the target level of 2.4 ppm for benzo(a)pyrene.
