The Outcome
The remediation efforts at the Bellozanne site successfully transformed highly contaminated excavated materials into acceptable levels for disposal and reuse. The contaminated material was treated effectively, allowing for its safe disposal at the La Collette facility and partly for reuse on the site. This outcome not only facilitated the construction of the sewage treatment plant but also contributed to environmental protection by ensuring that hazardous materials were managed responsibly.
How we did it
Hartigan arranged laboratory testing on the contaminated materials to assess hydrocarbon levels. Upon confirming significant pollution, our environmental team implemented a remediation strategy using chemically dosed windrows. This process of repeated dosing and turning effectively reduced contaminant levels to within acceptable ranges within a few months, followed by final assessments to ensure compliance with disposal criteria.
The Challenge
A major challenge was the discovery of highly contaminated materials during excavation, which complicated project timelines and required immediate remediation. The high hydrocarbon levels made direct disposal impossible, necessitating a tailored approach. Developing and executing this strategy under tight deadlines demanded close coordination and expertise, along with ongoing monitoring to meet environmental standards.
