Highlights: NORAM developed a groundwater treatment for highly contaminated water and soils at the former site of a mercury-cell chlor-alkali plant site. In the new process, lignin derivatives are dissolved in mercury contaminated water to complex mercury in an exceptionally stable form of a lignin-mercury colloid. The LIGNOR-ARD™ process to treat Acid Rock Drainage was the first product to emerge from NORAM's research during the project.

Scope of work: Management of the four-year $45-million remediation project, including technology development, testing and implementation.
