Strachan Street Ravine

Back To Map

COMPLETED 2022

3,500 m³ historic low-level radioactive waste
Waste deposited in the ravine by Eldorado Nuclear Limited in keeping with disposal practices of the 1930s and 1940s
Consolidated against the roadbed under clean shielding in the 1980s

Originally contaminated area was a steep ravine into which contaminated soils had been placed by end dumping
In 1988, waste throughout the ravine was consolidated into a mound on the north bank of the ravine
Site is currently secured with a low fence with signs noting its use as a LLRW storage site
LLRW consists of silty sand, gravel, organic material (including tree stumps), black and white ashy material, scrap metal, bricks, bottles, cinders, crockery, and chemical residues

Geomembrane cover will be cut, progressively exposing sections of LLRW to be excavated.
The waste will travel along the Central Transportation Route to the Long-Term Waste Management Facility
When the remediation and verification process is complete, the site will be backfilled in a series of lifts extending from the bottom of the ravine up the slope to Strachan Street
Fencing will be removed and top soil and grass will complete the restoration

Since the site is currently subject to a license under the Nuclear Safety and Control Act, regulatory administrative procedures will be carried out in association with site remediation to allow the site to be relieved of the licence
