    Other CLU-IN Webinars

    EPA's Region 10, ORD, and OSRTI hosted a three-part workshop series on hardrock mine geochemistry and hydrology in 2013. 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.
