Detailed Site Investigation

iStock_000010708514XSmallDetailed Site Investigations DSIs are used to delineate and characterise contaminant impacts to soil, groundwater and soil vapour.  DSIs are undertaken after contamination has been identified through previous investigations such as a Stage 2 Preliminary Site Investigation (Phase 2 Environmental Site Assessment). Prior to initiating remediation of a sites soil, groundwater or soil vapour, a DSI will provide the necessary information to prepare a remediation plan. Sage Environmental consultants will prepare a detailed site investigation methodology to suit your site specific conditions.

 

Typical investigation methods include borehole drilling and well installation to acquire subsurface soil, groundwater and soil vapour samples for laboratory analysis. DSI field data, and laboratory results are synthesized into a professional report that will meet applicable provincial or federal regulations.

 

Detailed Site Investigations involve;

  • A review of existing background information including Stage 1 and 2 PSIs
  • Development of sample and investigation planning
  • Performing the site investigation
  • Data interpretation, evaluation and reporting

 

Detailed Site Investigations are typically used to;

  • Delineate the extent of contamination in soil, groundwater or soil vapour
  • Supplement previous Stage 2 / Phase 2 work
  • Gather information in preparation for land remediation or site redevelopment
