WINISK: SITE 500
Mid Canada Line (MCL) Project
The ASU in collaboration with WESA Inc, were sucessful in tendering a bid for the 'Mid Canada Line (MCL)' cleanup project located at Site 500, Winisk, Hudson Bay (ONT). The project involves the cleanup and remediation of thousands of barrels, PCB and TPH contaminated soils and waters, paints, concrete and debris.

The Lab Trailer is equiped with two gas chromatgraph analyzers with electron capture detectors (ECD) and flame ionization detectors (FID). The trailer has a fumehood, oven, shaker table, rotory evaporation unit (with pump and temperature unit), sonic bath, emergency shower and a full office area for compilation and transmittion of results.
Up to 30 samples per day can be analyzed at the mobile laboratory for either polychlorinated biphenyls (PCBs) or for total petroleum hydrocarbons (TPH), also referred to as petroluem hydrocarbons (PHC). Barrels found on-site were analyzed for PCB content and for hydrocarbon identity. Water, concrete and sludge samples were also analyzed for PCBs and TPH.
All samples were analyzed and reported within a 32 hour time limit. This maximized productivity and minimized project down time.
Excellent progress was made in the 2011 season. Construction work proceeded rapidly. Over 20000 barrels were processed, asbestos was removed from all the buildings and most of the buildings were demolished. Many PCB and TPH contaminated soil areas were fully remediated to a strict regulation limit (<0.3ppm for PCBs).
The season started in June and the much of the cleanup work was concluded by October 2011. The 2012 season started in mid June and the final cleanup is scheduled for mid August 2012.
During the 2012 season, the on-site lab analyzed around 600 samples including TPH in soil, PCBs in soil, PCBs in oil, BTEX on badges (monitoring), PCBs on air tubes (monitoring), PCBs in paint/wood and PCBs in concrete.
Site 500 in the NEWS
“Crews and local residents in the northern Ontario First Nations community of Peawanuck are teaming up to begin the long-awaited cleanup at a Cold War-era military base. Site 500 is the largest of 16 mid-Canada radar sites scattered across northern Ontario. The base was home to several hundred people who worked at the site when it operated in the 1950s and 1960s.
The community has long been concerned about polychlorinated biphenyls (PCBs) and other contaminants in the site's soil getting into the food chain through the area's hunting and fishing grounds” – CTV News, Aug 2011.
