Environmental Assessments in Quebec

Environmental Site Assessment - Phase I

According to the Guide de caractérisation des terrains of the Ministère de l'Environnement et de la Lutte contre les changements climatiques du Québec, an environmental site assessment (ESA) - Phase I consists of:

  • Becoming familiar with the site

  • Define site-specific characteristics based on available data

  • Assess whether there have been activities that may have contaminated soil, groundwater and air in the past; and

  • Where appropriate, identify areas of potential contamination, determine the type of potential contamination and define additional information needs

What steps are taken in the Phase I ESA?

  • Access to Information requests

  • Consultation of listed documents and various organizations (municipality, ministry, Régie du bâtiment du Québec)

  • Site visit and interview with the owner

  • Observations from neighbouring properties

  • Final report with recommendations

Environmental Site Characterization - Phase II and Phase III

According to the Guide de caractérisation des terrains of the Ministère de l'Environnement et de la Lutte contre les changements climatiques du Québec, environmental site characterization (ESC) - Phase II consists of:

  • Confirming the presence or absence of a contaminant in the various environments (water, soil) and specifying the type of contaminant, if any, in the potential sectors identified in Phase I

Environmental Site Characterization (ESC) - Phase III consists of:

  • Determining the extent of contamination (area and depth) where the presence of contaminants was observed in Phase II

What steps were taken in Phases II and III?

  • Soil and groundwater characterization using boreholes or trenches: Tecosol has its own Geoprobe drill, as well as a manual drill for drilling in areas with restricted access.

  • Soil and water samples are taken from the characterization boreholes and sent to a laboratory accredited by the Ministry for chemical analysis. The parameters analyzed are determined based on environmental risks. Analytical results confirm the presence or absence of contaminants.

  • If the presence of contamination is observed, a phase III is recommended: phase III then involves additional drilling to clearly delineate the surface area and depth of the contaminated zone.
