Highlights

  • 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).

Upcoming Internet Seminars

The next webinar in our CLU-IN mining webinar series will address topics in soil remediation and restoration. Presenters will discuss their research on the use of soil amendments, the impact of soil restoration at mine sites on ecosystem function and services, and deliberate decision-making in site restoration that benefits the whole ecosystem.

Dr. Sally Brown will discuss how using residuals led to the development of new soil at a Jasper County, MO Superfund site. Her research team amended mine tailings at the site in the late 1990s and completed sampling in 2012. Dr. Brown will discuss the successful use of residuals at the site, as well as the ecological and economic values of using residuals even when replacement topsoil is readily available. The significance of considering the final fate of the site using a life cycle assessment will also be discussed.

Andrew Trlica will present his research that measured soil carbon storage in former surface mines under long-term reclamation. He compared areas reclaimed with biosolids-based soil amendments with areas reclaimed using conventional approaches. This study went on to use a life cycle assessment approach to examine the relative greenhouse gas balance and other ecosystem effects of different land reclamation strategies (for example, restoring a site to a low density residential use in comparison with restoring to a forest).

Upcoming Meetings

  • Mining History Association Annual Conference
    June 11-15, 2014 | Trinidad, Colorado
    Holiday Inn and Suites and Trinidad State Junior College

    The Mining History Association (MHA) annually holds a conference in a historic mining area. Each meeting includes program sessions with presentations on a variety of mining history-related topics. The 2014 MHA Conference may include topics such as Western coal mining history, coke in smelting metals, the coal/coke/iron and steel relationship, mine management-labor relations, the 1913-1914 coal strike, mine safety/accidents, life in a coal company town, and Rocky Mountain mining history.

  • The American Society of Mining and Reclamation 31st National Meeting
    June 14-19, 2014 | Oklahoma City, OK

    The American Society of Mining and Reclamation holds an annual meeting to facilitate technology transfer and information exchange between academic professionals, practicing reclamation specialists in the field, students, and all other interested persons.

  • National Conference on Mining-Influenced Waters: Approaches for Characterization, Source Control and Treatment
    August 12-14, 2014 | Albuquerque, New Mexico
    Sheraton Albuquerque Uptown Hotel

    The U.S. Environmental Protection Agency is sponsoring a national conference on mining-influenced waters in August 2014. The conference goal is to provide a forum for the exchange of scientific information on current and emerging approaches to assessing characterization, monitoring, source control, treatment and/or remediation on mining-influenced waters. Topics may include but are not limited to characterization, water treatment, beneficial use, source control/mine closure approaches, and prediction and modeling. A call for abstracts was recently announced for the conference. The abstract deadline has been extended and abstracts are now due by April 11, 2014. Online registration is expected to open soon. Check back here for information updates.

  • Remediation Technologies Symposium 2014
    October 15-17, 2014 | Alberta, Canada
    The Fairmont Banff Springs Hotel

    The Remediation Technologies Symposium 2014 is a remediation technology transfer event for environmental professionals, encompassing the latest innovations in soil and groundwater remediation. Some topic areas and case studies presented will include in-situ and ex-situ treatment methods, biological and non-biological treatment, thermal desorption, encapsulation, natural attenuation, multi-phase extraction, solar detoxification, electrochemical remediation, pre-treatment considerations, phytoremediation, environmental management, hydrocarbon and salt contamination, stabilization and containment, commercial situations, membrane technology, and unique and challenging locations.

 CLU-IN Mining Sites Webinar Series

 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.
