Phase II Environmental Site Assessment (ESA)

The objective of a Phase II Environmental Site Assessment (ESA) is to define the nature and extent of any environmental impacts at a site through an intrusive sampling program. 
 
The typical scope of work may include:

    • collection of soil, groundwater, surface water, sediment and/or vapour samples;
    • chemical analysis of samples for relevant parameters;
    • surveying the site and establishing groundwater flow direction;
    • determining the appropriate criteria to which the results must be compared;
    • interpretation of data, possibly including modeling, qualitative risk assessment, or development of a Conceptual Site Model;
    • preparation of a clear, comprehensive report documenting the findings and presenting a conclusion regarding the environmental condition of the site.

Terrapex Phase II ESAs are typically completed in accordance with the requirements of CAN/CSA-Z769-00, and meet the requirements of O.Reg. 153/04, Records of Site Condition.  Sampling protocols follow Ontario Ministry of the Environment guidelines, or, where appropriate, federal (Canadian Council of Ministers of the Environment) and/or other customer-specific requirements and protocols.

Phase II Environmental Site Assessment

We believe that communication throughout the implementation of the program is essential to its success.  Where possible, we work closely with our clients to ensure that the end product meets their requirements and leaves no unanswered questions.

 

Terrapex has completed numerous Phase II ESAs at a wide variety of sites, including service stations, dry cleaners, railyards, airfields, landfills, construction and maintenance yards, scrap yards, manufacturing facilities (for example breweries, steel plants, tire plants) commercial and retail properties, as well as greenfields.  We are experienced with all types of contaminants, including petroleum hydrocarbons, volatile and semi-volatile organic compounds, metals, polychlorinated biphenyls (PCBs), road salt and methane.  Terrapex has successfully filed numerous Records of Site Condition under O. Reg. 153/04.
