CSL Provided Impala Lac des Illes, tailings dam geotechnical, baseline environmental, field engineering support, analytical analysis and reporting. We appreciated the CSL collaboration with engineering contractors. The analysis was accurate and well documented. Provided on-time. I highly recommend working with the CSL team.

VP Environmental, Sustainability & Tailings Management | Impala Canada

CSL were the project engineers on the environmental work required to complete an expansion to our dealership. CSL completed an initial study to delineate potential environmental impacts in soil and groundwater that had entered our site from a neighboring property. The information and subsequent soil sampling were used to direct a contracting company to remove the contaminated soil from our property. CSL also designed and implemented environmental remediation measures to treat previously impacted areas and future-proof our property going forward. CSL were professional, completed their work safely and kept me informed during each step of the project. Their staff were friendly, responsive and courteous. I would highly recommend using CSL for similar projects.
