Environmental Site Assessments (ESAs)
are our core business.


A Phase I or Phase One ESA is a non-intrusive preliminary study entailing site history and inspection and documentary research. A Phase II or Phase Two ESA is an intrusive study in which soils and groundwater samples are tested.

Phase 1 ESA Services


Phase 1 ESAs are typically conducted along the following lines:

  • Connector.

    History

    Review existing historical records for the subject site and surrounding areas to identify actual or potential sources of environmental contamination

  • Connector.

    Inspection

    Perform a site reconnaissance (including existing buildings) to observe and document the present environmental condition

  • Connector.

    Information

    Perform interviews with knowledgeable persons and regulatory officials for additional information relating to any environmental concerns

  • Connector.

    Data Evaluation and Reporting

    Preparation of an engineering report summarizing pertinent findings, conclusions and recommendations

Following successful completion of a Phase One/Two ESA, a Record of Site Condition (RSC) can be filed with the Ministry of the Environment & Climate Change (MOECC) for inclusion into the Environmental Bill of Rights Registry.

At AiMS Environmental, our environmental engineers, scientists and technicians are highly qualified and experienced in conducting both types of ESAs. Our QPs have successfully filed over 30 Records of Site Condition over the past five years. Continually, we strive to provide the Client with the most cost-effective options, whilst delivering accurate, high-quality and well-presented ESAs that meet both Client and Regulatory approval.
