Engagement, partnership and continuity through multiple phases of work produces successful outcomes
This multi-phase project is a testament to the benefits of using an Environmental Contractor who has the regulatory and compliance requirement knowledge to tackle a site that requires a multitude of services to address environmental concerns.
Partnerships and collaboration have been a key focus in creating successful outcomes. Many of the Milestone team members have been involved in remediation activities over the years and with the PRB (passive reactive barrier) technology on other sites. When the PRB was installed at the site, it was the longest, widest, deepest PRB installed; an especially impressive feat given the tidal environment.
The initial phase was to rejuvenate, and extend, a PRB all using caisson drilling. Subsequent phases involved contaminated soil management and stabilization services, Milestone conducted soil excavation of contaminated soil, hauling to onsite storage cells, and disposal at a licensed, off-site facility. Additionally, Milestone constructed new soil holding cells, disposed of various waste streams (e.g., wood poles, concrete), backfilled excavations and rehabilitated site roadways.
Several phases of work were completed working with our joint venture partners, KFN Enterprises and the Kwikwetlem Nation. Together with the Kwikwetlem Nation Milestone excavated 40,000 m3 of contaminated soil. Cells were constructed on site for storage. Confirmatory sampling was completed, and soils were disposed of at a licensed, oﬀ-site facility. Hazardous waste materials were segregated and stabilized, prior to shipment. A cement silo was mobilized to site to allow for storage of bulk cement.
