  • 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

  • Screening, Testing, and Application of Residuals and Byproducts for Remediation
    December 2, 2015 | 1:00 PM - 3:00 PM EST

    This webinar in the CLU-IN mining webinar series is a follow-on to the seminar presented on July 24, 2014 on Using Biosolids and Coal Combustion Products for Soil Remediation at Mining Sites. The presenter will continue the discussion on using coal combustion products for soil remediation at mining sites, as well as discuss his recent research on screening and testing residuals, such as waste lime, gypsum, and paper mill sludge, for application on contaminated lands. Presentations will include case study data and findings that are supported by publications available from the presenter and collaborators' website www.landrehab.org.

    Upcoming Meetings

    • NAAMLP 37th Annual Conference
      September 28-30, 2015 | Santa Fe, New Mexico

      The National Association of Abandoned Mine Land Programs (NAAMLP) is a non-profit organization whose members include 31 States and Tribes conducting abandoned mine reclamation programs under the federal Surface Mining Control and Reclamation Act of 1977. This year's conference is hosted by the New Mexico and Navajo Nation AML Programs. The conference provides a venue to showcase reclamation successes and cutting edge technology on a national scale. Over 300 people from all over the country are expected to attend this conference. Subject matter includes: cutting edge reclamation techniques from across the country; geomorphic reclamation; revegetation research and success stories; hardrock safeguarding methods; bat habitat and preservation; the latest in GPS and GIS technologies; and others.

    • Remediation Technologies Symposium 2015
      October 14-16, 2015 | Alberta, Canada

      The Remediation Technologies Symposium 2015 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.

    • SETAC North America 36th Annual Meeting
      November 1-5, 2015 | Salt Lake City, Utah

      SETAC North America is a Geographic Unit of the Society of Environmental Toxicology and Chemistry (SETAC). SETAC North America is dedicated to the use of multidisciplinary approaches to examine the impacts of stressors, chemicals and technology on the environment. Abstracts for its 36th Annual Meeting are currently being accepted. The meeting will feature presentations on: molecular and cellular biology as they relate to environmental toxicology and chemistry; hazard and risk assessment, and environment/human health related issues; contributions to an understanding of ecological risk assessment and environmental hazards, including use and validation of mammalian models and systems; ethical issues related to environmental toxicology and chemistry and risk assessment; and others. Stay tuned for more details.

    • American Society of Mining and Reclamation National Conference
      June 4-10, 2016 | Spokane, Washington

      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.

    • International Mine Water Association Annual Conference
      July 11-15, 2016 | Leipzig, Germany

      The 2016 International Mine Water Association (IMWA) annual conference – Mining meets Water – Conflicts and Solutions – will be held at the KUBUS Leipzig. Conference themes include mine water regulation, hydrogeology, limnology/pit lakes, and geochemistry; water-related mine design; mine closure, remediation and follow-up care; dewatering and mine water treatment; mine water and climate change; water issues in lignite mining; secondary mining (mine waters, tailing, dumps); microbiology of mine waters and bioleaching; stable isotopes in mine waters; geotechnical issues related to mine water; hydrogeological and hydrogeochemical modeling; and process simulation tools.

     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.
