Phase II

In which context will you need to proceed with an Environmental or Characterization Site Assessment – Phase II?

As part of the financing or purchase of a property, the financial institutions require that the property be free of contamination. An Environmental Site Assessment – Phase II study is based on the potential or real risks of contamination raised in an Environmental Site Assessment – Phase I. An Environmental Characterization Site Assessment – Phase II is based on a potential risk of contamination on the property under study.

The methodology followed to fulfill this mandate is based upon recommendations given in the Canadian Standard Association document number CSA Z-769-00 which includes, among others, the following:

  • A review of past studies, reports or documents handed by the client or his representative.
  • Planning of sampling campaign.
  • Location of underground infrastructure.
  • Completion of field work.
  • Soil sampling.
  • Groundwater sampling.
  • Surface water sampling.
  • Chemical analysis of samples for relevant parameters.
  • Interpretation of data.
  • Preparation of a comprehensive report documenting the findings, a presentation of the study conclusions, and recommendations to address any environmental impacts noted onsite.

All procedures (soil sampling, transportation and conservation of soil samples) were carried out in accordance with the directives presented in the following documents produced by the “Ministère de l’Environnement et de la Lutte contre les changements climatiques” (MELCC):

  • Z769-00, “Évaluation environnementale de site, phase II” (confirmed in 2004).
  • “Politique de protection des sols et de réhabilitation des terrains contaminés”, june 1999, revised in 2000; as well as the Appendix I of the “Nouveau règlement sur l’enfouissement des sols contaminés”, july 2001.
  • “Guide d’échantillonnage à des fins d’analyses environnementales : Cahier 1 à 5” (1994 to 2001).
  • “Guide de caractérisation des terrains” (2003).
  • “Guide des méthodes de conservation et d’analyses des échantillons d’eau et de sols” (1990).

Treatment of contaminated groundwater either from Hydrocarbons or Volatile Organic Compounds (VOCs). A mobile treatment system can be installed on-site for groundwater treatment and daily sampling/analysis.

All works are conducted according to all regulations and guidelines provided by CCQ and/or CNESST.

A report will be presented within seven (7) to ten (10) working days from the date of the field work.

Ortam also performs Underground Storage Tanks (USTs) removals, which is the dismantling, pumping and removal of Underground Storage Tanks previously used to store heating oil or after a Gas Station decommissioning.
