Remediation

Why carry out a phase IV – Environmental Remediation study?

There are two scenarios for which environmental remediation is required.

  • In the context of refinancing or buying a property, financial institutions require their client to provide them with an Environmental Remediation study when it was proven that contamination in soil or/and water exist on the property.
  • A property owner may also wish to make a voluntary rehabilitation of the site.

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 (Confirmée en 2004);
  • Politique de protection des sols et de réhabilitation des terrains contaminés, juin 1999, révisé en 2000; as well as the annexe I du Nouveau règlement sur l’enfouissement des sols contaminés, juillet 2001;
  • Guide d’échantillonnage à des fins d’analyses environnementales : Cahier 1à 5 (1994 à 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 to you within seven (7) to ten (10) working days from the date of completion of the fieldwork.
