Water treatment (mercury, toluene, PAH, and various metals) following spills or during contaminated site restoration work.

Plans and specifications, and sites restoration work supervision including excavation, pumping, In Situ treatment (biodegradation, bioslurping, bioventing).
-
Design, installation and operation of water treatment units (separator, removal of volatile organic compounds, etc.).
-
Biogas management on a former landfill site in order to develop residential and recreational sites.
-
Evaluation and design of an In Situ groundwater treatment system for volatile organic compounds present in a low permeability matrix.
-
Evaluation of In Situ contaminated soil and groundwater treatment technologies on an industrial site located over a highly porous aquifer used as a drinking water source.
-
Installation and monitoring of a hydraulic dam equipped with tie-in trenches, a pumping system and a groundwater treatment unit, in order to stop contaminant migration beyond site limits and municipal sewage system infiltrations.
