Approximately 4,100 m3 historic low-level radioactive waste (LLRW) deposited into steep ravine by Eldorado
Majority of LLRW located on east slope of site and also on west slope of ravine, possibly as result of dust from dumping on east slope
Historical stack deposition may also have contributed to elevated levels of contamination
Wooded ravine with steep forested slopes
Bounded to south by CP rail embankment, to north by forested lands, west by a golf course, east by residential properties
Remediation/Restoration Plans
Secure site through fencing and gates as appropriate
Remove LLRW in a series of lifts to ensure safety and stability of slopes
Relocate Alexander Creek and build coffer dam
Excavate LLRW under creek bed and along lower portions of east bank
Transport the waste by truck along the South Transportation Route to the Long-Term Waste Management Facility
Once remediation is complete, return creek bed to original location, remove temporary road, re-contour remediated east ravine slope to variable gradient, replace trees, seed and mulch surface, remove gate and fencing
Special Considerations
Classified as a terrestrial habitat complex, important wildlife corridor
