An Environmental Site Assessment (ESA) is undertaken as a systematic, phased process, as defined by the Canadian Council of Ministers of the Environment (CCME), with well defined objectives.

The Phase I ESA, as per the Canadian Council of Ministers of the Environment (CCME) and the Canadian Standards Association (CSA), is required by financial institutions and for facility owners, operators and purchasers, to demonstrate `due diligence` in order to mitigate risk associated with impacted properties. An ESA may document `baseline` or current conditions to avoid liability for future environmental impairment. In some cases, property owners/managers may rely on a Phase I ESA to hold lessees accountable for activities leading to adverse impact.

The Phase II ESA, as defined by the CCME and CSA, involves intrusive testing of materials, air, soil, surface water and groundwater, to identify and/or confirm the presence or absence of adverse environmental impact. The key to an effective and accurate Phase II ESA investigation is the collection of representative samples and the preparation of defensible conclusions by experienced professional and technical staff.

Waste and contaminant characterization and management:Excavation, recovery, and off-site disposal or treatment of impacted soil and/or building materials. Free-phase product recovery, transport and off-site disposal or treatment. Containment, encapsulation, immobilization of contaminated soil and groundwater. Recovery, treatment, discharge and/or recharge of impacted groundwater. In-situ natural attenuation, enhanced bioremediation. Ex-situ biopile and bioreactor design and construction. Soil vapour extraction; soil venting; air sparging.

The primary objective of a Phase III as defined by the CCME and the CSA involves intrusive testing of materials, air, soil, surface water and groundwater, to identify and\or confirm the presence or absence or adverse environmental impact. The key to an effective and accurate Phase III ESA investigation is the collection of representative samples and the preparation of defensible conclusions by experienced professional and technical staff.
