Containment and restoration technology development for DNAPL in fractured bedrock (an overview of the Smithville Phase IV Program)
- Smithville Phase IV Bedrock Remediation Program, Smithville, Ontario (Canada)
Currently, no proven technology exists for containing and restoring fractured carbonate bedrock environments that have been contaminated by Dense Nonaqueous Phase Liquids (DNAPLs). Over the past decade Canada`s Orphan Sites Program and the US Superfund Program have spent billions of dollars on site restoration and yet not one DNAPL site has ever been successfully cleaned-up. Current research and technology development efforts are generally less than five years old and have focused on porous media research. Fractured media flow and contaminant transport are recognized as much more complex issues, but have received comparatively little attention. It is estimated that there are hundreds of fractured rock DNAPL contaminated sites in Canada and the United States. The Smithville Phase IV Bedrock Remediation Program was established to contain and remediate a DNAPL spill site in a carbonate bedrock aquifer located in the Niagara region, Canada. The program recognizes the need to develop new technical solutions and is doing this through site specific investigations, laboratory studies, modelling and pilot scale tests of promising containment and restoration technologies. An innovative management structure has been established to direct the final stage of this project through an agreement of common interest with all former stakeholders. This independent Board`s directive is to contain and remediate the DNAPL remaining in the ground beneath and adjacent to the site and to form partnerships with world-renowned scientists and researchers to develop and implement leading edge technology. This paper provides an overview of the challenges, plans and accomplishments of the Smithville remediation project. The innovative management approach applied at the site has reduced bureaucracy and costs and has promoted partnership and consortia arrangements that are now being realized for site funding.
