YMX International Aerocity of Mirabel - Installation and operation of a groundwater pumping and treatment system

The project consists of the installation of five pumping wells to pump groundwater, perform groundwater treatment, and discharge treated water into injection wells and the Belle-Rivière River within the airport boundaries. The treatment applied will be through a series of activated carbon filters, an effective treatment for the treatment of organic compounds, particularly those targeted in this project. Filters will be present upstream of the activated carbon to remove suspended solids. In addition to the installation of the treatment unit, excavation and compaction of land in order to install a building that can accommodate the treatment unit as well as an underground reservoir for groundwater storage are planned. All measures will be put in place to ensure that the project's activities do not have a negative impact on groundwater quality since its objective is to improve this quality.

Latest update

September 22, 2020 - ADM Aéroports de Montréal has determined that the project is not likely to have significant adverse environmental impacts. In fact, the main objective of the project is to improve groundwater quality, thus improving the quality of the environment. Measures will be taken to mitigate impacts on flora and fauna. The main measures are: cutting down trees outside of migratory bird nesting periods; managing invasive exotic species; protecting wetlands present in the sector; implementing measures to limit suspended solids in the Belle-Rivière; and limiting encroachment into fish habitat.  Groundwater level measurement wells will be installed to ensure that there is no variation in the level of the water table so as not to cause a lowering of the level that could affect water wells to the south.

Therefore, ADM may proceed with the project..
