Soil containing toxic leftovers from boilers and refrigeration units
does 'not pose hazard to human health,' says City

OTTAWA — Some Glebe residents want the province to impose better safeguards on the construction of a large earthen berm at Lansdowne Park.
The 10-metre high berm, which is to be built east of Frank Clair Stadium, will include tonnes of contaminated soil excavated from the construction site.
The City of Ottawa could have trucked all of the soil to a landfill, but instead chose to reuse most of the excavated material, which contains petroleum hydrocarbons, heavy metals and poly-aromatic hydrocarbons.
The chemicals are toxic leftovers from boilers and refrigeration units that once operated on the 15-hectare site.
Part of the site was also contaminated by garbage — up to five metres deep in places — which was used to fill in an old inlet from the Rideau Canal.
The landfill included materials such as wood, metal, ashes, cinder, coal, bricks and decayed organic material.
