Sonic completes first phase of Toronto area soil cleanup project

VANCOUVER, BC-Sonic Environmental Solutions reports that it has completed the first phase of its contract in the Greater Toronto Area (GTA) on schedule. The company's first GTA project is at a brownfield industrial site with levels of polychlorinated biphenyl (PCB) contamination ranging up to 20,000 parts per million (ppm). Sonic used its mobile remediation system at the site, and follow-up independent soil testing has confirmed that the system has cleaned the contaminated soil to the target levels required by the Ontario Ministry of Environment (MOE). Once treated, the soil is placed back on site, eliminating the need to import clean fill. Larry Rodricks, Sonic's vice-president of remediation services, said, "We have successfully treated soil at this site to below residential redevelopment levels...Our earlier treatability tests were confirmed by our results from operations at site as expected. We will be processing up to 2,500 tonnes within the time frames specified by our client. The process is scaleable so we will be able to adjust to greater volumes as needed." The project is being completed in co-operation with the prime contractor, a national environmental services company responsible for progressively excavating the contaminated parts of the site in a precision manner based on prior site assessment data.
