Contaminated Sites and Remediation

We offer contaminated sites assessment, investigation and remediation management services. These measures are most often applied on commercial properties prior to acquisition, sale, divestiture, lease or financing. The same methods may be applied to any area where soil, water, groundwater and, or soil vapour contamination is a concern.

Appropriate consideration and due diligence is at the core of our Contaminated Sites and Land Remediation services.

 

Stage 1 PSI or Phase 1 ESA


Valhalla Environmental Consulting provides Stage 1 Preliminary Site Investigations (PSI) that meet:

  • CSA Standard “Z768-01 Phase 1 Environmental Site Assessment” – Phase 1 ESA
  • Canada Mortgage and Housing Corporation CMHC guidelines
  • The requirement of the BC Ministry of Environment (MoE)

Stage 1 Preliminary Site Investigation (PSI): Also referred to as a Phase 1 Environmental Site Assessement (ESA) is a method used to assist in determining potential environmental liabilities due to contamination on a site or property. This process involves a detailed review of land uses and history including a site visit, record searches, personal interviews and the evaluation of related information and reporting. This information is compiled and used to determine the potential of impact on a site due to contamination.

A Stage 1 PSI or Phase 1 ESA are typically used to:

  • meet a regulatory request, order or direction
  • provide a liability assessment prior to an acquisition or divestiture of a property or site
  • provide a due diligence measure in support of a real estate or financing agreement
  • provide baseline liability assessment prior to tenancy of a site
  • provide a due diligence measure to determine compliance with a corporate stewardship policy

 

Stage 2 PSI or Phase 2 ESA


 Valhalla Environmental Consulting provides Stage 2 Preliminary Site Investigations (PSI) that meet:

  • CSA Standard “Z768-01 Phase 1 Environmental Site Assessment” – Phase 1 ESA
  • Canada Mortgage and Housing Corporation CMHC guidelines
  • The requirement of the BC Ministry of Environment (MoE)

Stage 2 Preliminary Site Investigation (PSI): Also referred to as a Phase 2 Environmental Site Assessment (ESA) these investigations involve environmental sampling and analysis to determine the degree of contamination and characterize the type of contaminant(s).

A Stage 2 Preliminary Site Investigation involves:

  • a review of existing background information including Stage 1 PSI
  • development of sample and investigation planning
  • performing the site investigation
  • data interpretation and evaluation reporting

A Stage 2 PSI or Phase 2 ESAare typically used to:

  • confirm the findings of a Stage 1 / Phase 1 investigation
  • supplement previous Stage 2 / Phase 2 work
  • gather information in support of Remediation measures or site redevelopment
  • establish a baseline of environmental conditions for a further Detailed Site Investigation
  • provide a due diligence measure to determine compliance with a corporate stewardship policy

Remediation is applied to mitigate, decrease or eliminate existing contamination.

 

Land Remediation is most often required when sites have contamination of soil, groundwater or soil vapour at levels above regional environmental standards. In BC the most common standards of comparison are defined in the BC Contaminated Sites Regulation (CSR). Land Remediation is usually undertaken after preliminary (PSI) of detailed (DSI) assessments to outline and characterize site contamination.

Land Remediation management at Valhalla Environmental Consulting means we will work with you to find the best solutions for your project site. While our multidisciplinary team of staff and associates are well versed in standard remediation measures, we are always looking forward to innovative and effective options to integrate into our solutions toolkit.
