2006 MEND Maritimes

The MEND Maritimes Workshop was a regional MEND workshop held in Halifax, NS on May 23-25, 2006 and co-hosted with Dalhousie University. The theme was “Challenges in Acidic Drainage: Case Studies on Mitigation Technologies and Current Research”. Presentations featured case studies on various aspects of the closure plan for the Cape Breton Development Corporation. Field-scale results included management, long-term monitoring and closure performance at various Canadian mine sites. A toolbox of technologies were examined for passive and active treatment of acidic drainage effluent, and options presented for the management and disposal of lime treatment sludge. Challenges faced by regulators were laid out in presentations on the booming mining industry in BC, and reclamation bonding in Alaska. Lessons learned in policy and planning related to ARD were exemplified by presentations on the geology of the Halifax Regional Municipality and the Halifax airport. An all-day field tour visited sites that exhibited the impacts of acidic drainage on the city of Halifax.
