Environmental Site Assessment and Rehabilitation

Download the brochure

Since the 1990s, environmental expertise has become increasingly important in matters of property management and financial transactions involving properties. Le Groupe Gesfor's team has the training and skills needed to take action at every step of an environmental site assessment. Here are some of the services we can offer you:

 

  • Environmental site assessment and rehabilitation

    1. Environmental site assessment (Phase I): This determines the environmental condition of a site based on an examination of past and present practices and activities. The Phase I assessment normally includes a review of aerial photographs, a title search, a review of historical and current information, as well as a site visit to inventory the hazardous materials present and potential risks associated with the soils and groundwaters of the property.

    2. Preliminary environmental site characterization (Phase II): This characterizes in greater detail the environmental condition of the site, usually following the recommendations issued in the Phase I assessment report. During Phase II, samples of waters, soils and/or residual materials are collected on the site and analyzed in order to detect the presence of contaminants related to past or present site activities. The Phase II characterization helps to determine whether or not rehabilitation is needed and, if so, to evaluate the options and prepare cost estimates.

    3. Exhaustive environmental site characterization (Phase III): This is required when it is necessary to specify the contaminated areas and the quantities of contaminated materials found during the previous assessments. The Phase III characterization is used to optimize cost estimates for site rehabilitation and recommend the appropriate rehabilitation method.

    4. Environmental site rehabilitation (Phase IV): When contamination has been found during the Phase II and Phase III studies, site rehabilitation is undertaken in order to re-establish the environmental quality of the contaminated site. We have the expertise needed to suggest to our clients several optimum methods of decontamination or treatment that will help reduce decontamination costs. Here are some methods proposed by our firm:
      - Excavation and disposal at an authorized site
      - Chemical oxidation of contaminated soils
      - Biotreatment of hydrocarbon-contaminated soils
      - Introduction of mitigation measures
      - Treatment of underground water

  • Dismantling and management of petroleum equipment
    1. Assessment of compliance and pressure testing of tanks
    2. Dismantling of underground or aboveground tanks for residential, commercial and industrial facilities
    3. Characterization and management of contaminated soils
    4. Site rehabilitation
  • Assessment of contaminant impacts
    1. Assessment of environmental impact, accumulation and disposal of industrial chemical products such as polychlorinated biphenyls (PCBs), perchloroethylene (PCE) and polycyclic aromatic hydrocarbons (PAH)
    2. Biotreatment of petroleum hydrocarbons
    3. Evaluation and management of the environmental aspects of the use, management, bioaccumulation and disposal of pesticides
  • Environmental compliance study
    This type of assessment allows a company to ensure that it complies with current standards (permits, health and safety, storage, waste, etc.), while improving the effectiveness of operations by proposing solutions adapted to the company's needs.

  • Management of residual materials
    This service helps to identify solid wastes and hazardous materials (asbestos, lead-based paints, etc.) and plan effective management during various dismantling, excavation and disposal work.

 

We systematically follow up on each of our assessments with a report that includes conclusions and recommendations on the actions to be taken.
