New from MEND is the report: Assessing the Long Term Performance of a Shallow Water Cover to Limit Oxidation of Reactive Tailings at Louvicourt Mine (July 2007)

The report investigates the impact of periphyton layers on the performance of shallow-water covers to prevent oxidation of reactive tailings at Louvicourt Mine. This study was initiated nine years after the tailings were submerged, and integrates geochemical, mineralogical and biological data to provide an overall assessment of the long-term performance of the shallow water cover. Results indicated that development of the overlying biofilm was beneficial in preventing metal release to the overlying water column. Recommendations were made for future studies to expand the understanding of biofilms in tailing impoundments.

Report available in hard copy for $35.00 Cdn. (plus applicable taxes).
