REMEDIATE: Sustainable Remediation
Vivenda Remediation and
Development Project Made
Possible using a Novel Approach –
Montréal, Que.
AS PART OF A CONDOMINIUM construction
project by a developer (Vivenda) the
environmental remediation of the property
located on the site of a former quarry, in
Montréal was to be carried out. An industrial
building was demolished in 2015, and the land had been vacant prior to this project. ALTRA
| SANEXEN proposed a remediation approach combining excavation of contaminated
soils up to the level of the groundwater table, in-situ treatment of soils contaminated by
petroleum hydrocarbons and a risk assessment to leave the contaminated soils with metals
in place. A decision-making diagram was integrated into the remediation plan to include
a technical impracticability option, allowing an end to the in-situ treatment, a signi昀椀cant
departure from the established procedure.
Project Team: Vivenda, Sanexen Environmental Services Inc., Ministère de l’Environnement, and de la Lutte contre les changements climatiques, de la Faune et des Parcs.
