Site Contamination Investigations

Concerns over contaminated property and the expanded responsibilities for clean-up costs have heightened in recent years, especially among lending institutions. More stringent provincial laws have been passed, establishing "joint and several liability" for contaminated sites. This legislation casts a wide net over both current and past owners, current and past operators, as well as others involved in property transactions and development.

We conduct Stage 1 and Stage 2 Preliminary Site Investigations (also known as Phase 1 and Phase 2 assessments) to assess potential risks for contamination to have occurred (Stage 1), and confirm through soil and groundwater testing (Stage 2) that contamination is either absent or present at a site.

Whether it's for a property transaction, re-development planning, or just for prudence, understanding the risks for site contamination at a property starts with a Stage 1 investigation. Stage 1 investigations examine the risk of site contamination based on past and present use of the site as well as surrounding properties, and generally include:

  • Research on historical land uses
  • Interviews with knowledgeable sources
  • Visual site inspection and photo documentation
  • Assessment of the risk of site contamination and recommendations for further action if needed

Based on the results of a Detailed Site Investigation, a Remediation Plan describes the methods, sequence, timeframes and costs entailed in cleaning up contamination found at a site.

A Confirmation of Remediation Report documents the remediation actions implemented and provides verification that contamination has been removed. Sometimes, when physical remediation is either not possible or not practically feasible, site contamination can be dealt with by Risk Management instead.

Phoenix Environmental has helped our clients with all stages of contaminated site investigations, including obtaining Certificates of Compliance (following remediation) and Conditional Certificates of Compliance (risk management), in compliance with British Columbia's Contaminated Sites Regulation.
