Land at Edmonton City Centre Airport has only a small amount of contamination, according to a consultant's report released by the city on Thursday.

"This is good news, as it will allow developers and future homeowners to have confidence in the safety of this neighbourhood," Phil Sande, the executive director of the City Centre Airport Land Redevelopment Project, said in a news release.

"It also means that the city’s potential clean-up liability is expected to be very limited in scope and cost. Clean-up costs can be more well-understood, and likely quite reasonable."

AECOM, an independent consultant, drilled and sampled soil at 25 locations covering half the airport property. The sites were chosen to include areas that might be contaminated due to past uses at the airfield.

Only three of the 25 samples will require follow-up testing to determine the extent of the contamination though the city expects the results to show that it is limited.

The city is in the process of shutting down City Centre Airport in order to free the land up for housing and LRT development.

However, pro-airport group Envision Edmonton collected about 92,000 signatures in a bid to force the city to hold a plebiscite on the issue.

The group wants the airport to stay open.
