Services // Remediation & Risk


Hello, I’m Sylvain Bordenave, Practice Area Lead for Risk and Remediation at Trace Associates Inc. At Trace, we support clients with their contaminated sites management by using a pragmatic approach in line with regulatory guidance and with full consideration of client objectives. Building upon a thorough understanding of environmental conditions at a site, a risk-based approach allows us to identify and focus on relevant factors that have the potential to have an impact on human health and ecological risk.

A risk based approach ensures effective contamination management where remediation is necessary. This corporate philosophy ensures we serve clients in both a practical and scientifically sound manner, while maintaining protection of human health and the environment.

Trace’s experienced professionals work on all types of land uses from brownfield urban redevelopment sites to legacy oil and gas refineries. By applying effective risk strategies coupled with practical, targeted remediation, we can limit environmental impacts, accelerate liability reduction, and reduce costs. With a good understanding of client objectives and regulatory obligations, our specialists determine how to best manage environmental risks related to contaminated sites.
