This treatability study was completed in 2002 in our Wisconsin greenhouse. This bench-scale test was designed to determine which of the Indian Mustard genotypes were best suited to remove elemental lead from soils contaminated by lead. The contamination accumulated in soils adjacent to several Lake Michigan lighthouse facilities as a result of decades of scraping lead-based paint. The remedial alternative being considered previously was to scrape the soils and take them by boat to a Wisconsin Landfill.

SCC successfully completed the treatability study allowing for:

• Site-wide deployment of optimum genotypes as determined from the study
• Demonstration of efficacy of the technology for clients and regulators at this lead-contaminated lighthouse facility and other similar sites
• Reduced potential remediation costs by at least 85% relative to other options evaluated for this site.
