Environmental Site Assessments
During ESA phase 1 Martech Group engages in site reconnaissance and reviews any and all available records for the subject site. This phase provides a timeline of all the events that are within the records available at various regulatory and government agencies. These records are reviewed by the investigator according to the provincial laws and regulations. ESA Phase 1 is intended to determine potential environmental liabilities and to establish the basis for further investigative work.
An ESA Phase 2 is carried out if the investigator carrying out ESA Phase 1 is in doubt that contamination is present on site. During Phase 2, Martech Group carries out an intrusive review of the site conditions rather than a non-intrusive review of records. Samples obtained are sent to approved laboratories for testing. Depending on the outcome, a site delineation maybe required to provide precise map of the contamination (whether soils, or building materials) and further testing is implemented. Once the Phase 2 ESA is complete, Martech would either recommend moving to the third phase of the process (Phase 3 ESA), or to confirm that no contamination is found (if Phase 2 testing was compliant).
Phase 3 ESA is where the remedial work is planned by Martech Group. This phase commences on the basis of the former Phase 2 ESA. The mitigation planning (remediation planning) is carried out in conjunction with the contracted environmental remediator.
