Environmental Site Assessments (ESA) and Site Investigations
ESAs and site investigations are integral to the successful development of a project. Tervita’s team of experts is well versed in varied assessment and investigation requirements for upstream and downstream sites in Western Canada. The assessments are planned in stages or phases to ensure environmental compliance. Phase 1 ESA, and Preliminary Site Investigations in BC, are used to evaluate historical and current land use and assess whether a site may have potential areas and contaminants of environmental concern.
Phase 2 ESAs and Detailed Site Investigations, use sampling and testing to quantify and analyze the extent of contaminants within any identified areas of environmental concern. This data allows our team to better understand the environmental risks and develop a cost-effective and expedient plan for the site. Tervita is experienced with site-specific guidelines (example: Tier 2 criteria) including pathway exclusion, criteria modification and the use of the Alberta Subsoil Salinity Tool.
