Soil-Contaminant Delineation and Remediation, Groundwater Monitoring, and Pollution Prevention for a Former Metals Recycling Facility

Project: An industrial property within inner-city Calgary had been used as a metals recycling facility since the 1950s. During redevelopment of environmental operating approvals with the Alberta government, the operator declared bankruptcy. The regulator expressed concern for worker and public safety based on 10-year-old soil quality information and mandated an update to site characterization to assess soil and groundwater quality, and to follow-up with remediation, if necessary.

Services: Reviewed historical environmental site assessment and remediation documents. Met and fostered a positive relationship with the environmental regulator, on behalf of the client. Planned and managed a phase 2 environmental site assessment to delineate impacts to soil and groundwater quality to the satisfaction of the regulator. Developed risk-based remediation objectives and gained regulator approval for those objectives and the remediation plan. Managed the schedule, budget and technical aspects of the remediation program to remove contaminated near-surface soils at Site, remove a source area, and document soil quality at the property periphery. Challenges to the project were the need to complete the remediation work under frozen conditions to meet client schedule, and discovery of buried materials and soil conditions not identified as part of the assessment program. Spoke continued to monitor groundwater quality at the site post-remediation to document changes (improvements) over time and provided advice regarding preventing further land and water contamination once the property was leased to a new industrial tenant.
