  • When Supply does not Meet Demand (Contaminated Sites Report 2008)

    During the next few decades, federal, provincial, and municipal governments, as well as the private sector, will commit large sums of money to clean up contaminated sites across Canada. A combination of regulatory and economic drivers will keep the sector buoyant, resulting in a strong demand for labour to work on contaminated sites. Between 2004 and 2019, the federal government has committed up ...

  • Resuspended contaminated sediments cause sub‐lethal stress to oysters: A biomarker differentiates TSS and contaminant effects

    Resuspended contaminated sediments (RCS) represent an important route of contaminant exposure for aquatic organisms. Filter‐feeding organisms are exposed to contaminants, both in the dissolved (at the gills) and particulate form (in the digestive system), during resuspension events. In addition, these organisms must manage the physical stress associated with an increase in total suspended ...

  • White Paper: Soil Data Quality Control

    Why it is essential during a contaminated soil study? Before starting an evaluation of the contamination leading to decision-making tools for site clean-up, it is essential to ensure data quality. Thus, based on solid and reliable foundations, uncertainties occurring during the different steps of the decision process will be better controlled and the final quality of the project ...
