CLU-IN Webinar Series on Mining Sites - OSRTI's Technology Innovation and Field Services Division launched a CLU-IN webinar series on treatment technologies at mining sites in June 2012. Topics include technology transfer, innovative and ecological approaches to dealing with mining waste, reuse and recovery technologies, and other related focus areas. The webinars are held on a quarterly basis and listed under Upcoming Internet Seminars (below). Archives of past webinars can be found under Archived Internet Seminars, Videos, and Courses.
Region 10 Workshops on Hardrock Mine Geochemistry and Hydrology - EPA's Region 10, Office of Research and Development (ORD), and Office of Superfund Remediation and Technology Innovation (OSRTI) hosted a three-part webinar series in February and March 2013 that focused on evaluating the potential for contaminant release from hardrock mine sites. Topics included water chemistry, potential sources of contamination from mine sites, and mitigation and reclamation practices to protect natural resources. Information on webinar archives and resources can be accessed below through Workshops on Hardrock Mine Geochemistry and Hydrology or downloaded (1pg, 222KB).
The 10th International Conference on Acid Rock Drainage (ICARD) and the International Mine Water Association (IMWA) Annual Conference will be held as a single conference in Santiago, Chile in 2015. The conference will be a unique opportunity to gather the newly-formed local and South American acid drainage and mine water community. Conference themes include geomicrobiology; biogeochemical cycles and biomining; applied mineralogy and geoenvironmental units; prediction of drainage flow; prediction of drainage chemistry; mine water and drainage collection and treatment; dry covers; scaling from laboratory to field studies; reliable mine water operation; mine water management for closure; mine water geochemistry. Registration is open and can be completed at http://www.icard2015.com/english/registration.
The 2015 Annual Conference of the Mining History Association (MHA) returns to Virginia City, Nevada, June 11-14, 2015. Virginia City was the location of the first MHA meeting in 1990 as part of the Western History Association conference. For its 25th — Silver — Anniversary, the MHA will return to the Comstock Lode, site of America's first great silver boom, for a series of events, tours, and sessions. Stay tuned — the conference program will be available in early 2015.
Workshops on Hardrock Mine Geochemistry and Hydrology
EPA's Region 10, ORD, and OSRTI hosted a three-part workshop series on hardrock mine geochemistry and hydrology. The goals included enhancing participants' understanding of the key issues regarding water chemistry predictions, identifying potential sources of contamination from mine sites, and describing practices to mitigate or reclaim facilities to protect natural resources. Presenters included experts from EPA Headquarters, Regions, and ORD; the U.S. Geological Survey; and the U.S. Forest Service. The workshops were open to all agencies, tribes, consultants, and the general public, and are now archived and available for streaming. Supplementary materials and resources provided by the instructors are also available for download below.
