Environmental Assessment

 Phase I Environmental Site Assessments (“Phase I ESAs”) have become an integral part of due diligence research on the site conditions of residential, commercial and/or industrial properties. Here at SGETEC Consultants we perform Phase I ESAs to identify actual and/or potential site contamination in accordance with the Canadian Standards Association Standard Z768-01, American Society for Testing and Materials Standard Practice E-1527-00 or other international regulations and standards.

A Phase I ESA of your property involves the systematic gathering of information to identify actual or potential contamination, or source of contamination. A phase I ESA may include but is not limited to:

  • Reviews of the property histories through the use of aerial photographs, insurance maps, land title searches, municipal and provincial archives, etc.
  • Interviews with present and/or past occupants, present and/or past neighbors, and government officials.
  • Site visit to verify any discrepancies noted in the historical information or the review process.
  • Regulatory and deed searches on the site.

A Phase I ESA does not regularly involve sample collection or analysis.


  • Phase I ESA helps to reduce uncertainty about potential environmental liabilities.
  • Phase I ESA can be used as a basis for further investigation of the residence.
  • Phase I ESA report can be used to make informed decisions about residential property value and transactions.
  • Phase I ESA is used to identify certain baseline environmental conditions, to assist in meeting regulatory requirements and as an initial step in site remediation.

SGETEC Consultants also performs Phase II Environmental Site Assessments (Phase II ESAs) to determine the nature and extent of any potential contamination at a property. Based on recommendations provided in the initial assessment (Phase I ESA), we develop a soil and water sampling program for Phase ll ESA of your property to be conducted at the site by staff together with subcontractors. The sampling strategy of Phase ll ESA of your property may include the evaluation of adjacent properties if previous information indicates that there is a potential for off-site contaminant migration towards the site under investigation. We subcontract services only to knowledgeable professional drilling companies that have previous experience working with Environmental Site Assessments and the surrounding areas.

Based on laboratory results and field observations, SGETEC Consultants investigation determines the presence, nature, level and extent of surface and subsurface contamination, and other site conditions. In our final report, on the Environmental Assessment of you property, we characterize and interpret this information to assess the potential risk to the site and/or adjacent residential properties. A Phase II ESA may be intrusive and require additional detailed sampling in order to delineate the horizontal and vertical extent of soil/groundwater contamination.

Record of Site Condition (RSC) is required under the Environmental Protection Act (EPA) and Ontario Regulation (“O. Reg.”) 153 as amended on July 1, 2011. As results of the amendments, a property owner is required to submit a clear and transparent RSC, including clear Environmental Site Assessment (ESA) requirements which reflect best practices.

Only Qualified Persons (QP) should be filling submitting a RSC on property owner’s behalf. Soil quality standard defining the quality of soil must accompany a RSC.

Any other EIA, Phase 3 or any country Environmental impact assessment, Environmental baseline studies, EMP and EMS studies can be done by SGETEC Consultants.
