Course curriculum

In the webinar, we describe key recent developments for the soil vapour conceptual site model, preferential pathways and investigation approaches and methods. Drawing upon current research, guidance, and practice, the webinar provides a broad perspective on current practices and common questions, but also highlights jurisdiction-specific protocols and guidance including BC Provincial and Canadian federal regulations and guidance
