The National Capital Commission is paying $4.9 million to two contractors to remove contaminated soil from LeBreton Flats.
Milestone Environmental Contracting and R.W. Tomlinson were awarded the remediation contract from the Crown corporation after submitting the lowest of five bids for the project.
The 6.5 hectares to be cleaned up are located just south of Sir John A. Macdonald Parkway and west of Booth Street. The project is expected to be completed by December 2013.
Site investigations, according to an environmental assessment report, have revealed that the soil is contaminated with metals and hydrocarbons.
The cleanup, says a staff report, will cause closures of the property’s pathways and trails.
