The following text was excerpted from marketing information provided by GSI Environnement<br />
(formerly Ecosite, <strong>In</strong>c.), 965 Newton Ave., Office 270, Québec City, Qc. Canada G1P 4M4 in<br />
August 1998:<br />
The site was contaminated with transformer oil and PCBs. <strong>In</strong>itial concentrations were 60,000 ppm<br />
MOG and 20 ppm PCB. The 1,000 m3 (approx. 1,300 yd3) contaminated zone extended from 0,0<br />
to 1.5 m (0.0 to 4.9 ft) below ground surface (bgs), and was comprised of heterogeneous silty<br />
backfill material. After performance of a risk assessment, treatability studies were conducted in the<br />
laboratory, and ultimately, surfactants were developed which would provide highly efficient<br />
treatment of the source material. To lower concentrations to a non-toxic level for biodegradation<br />
to take place, <strong>In</strong>jecsol TM enhanced in situ soil flushing was applied to the contaminated matrix,<br />
and the site remediation was completed with in situ bioremediaiton. The <strong>In</strong>jecsol TM technology<br />
was used for enhanced flushing, nutrient injection and free phase recovery. All work was done<br />
without interruption to plant activities or dismantling of existing infrastructures. The contaminant<br />
levels were lowered to 5,000 ppm (MOG) and 10 ppm (PCB). The project was performed over a<br />
one year duration, at a cost of +/- $300,000. (Canadian).<br />
