Upcoming Internet Seminars

  • EPA Mining Sites Webinar Series: Successful Implementation of Biologically-Based Passive Remediation Systems
    Tuesday, May 1, 2018 | 2:00-3:30 pm EDT(18:00-19:00 GMT)

    This webinar will highlight how biologically-based passive remediation technologies have been shown to be a cost-effective option for treating mining-influenced water, especially mildly to moderately impacted waters at low- to moderate-flow rates, such as may be found at remote or closed mine sites. Two case study examples of such systems will be presented: Iron King Mine near Jerome, Arizona, and Garfield Mine near Delta Colorado.

Upcoming Meetings

  • Workshop on Mine Water Management and Remediation: From Ground Water to Mine Water
    April 24-27, 2018 | Mikkeli, Finland

    Lappeenranta University of Technology and the International Mine Water Association are offering this short course focusing on general mining aspects to help understand the formation of mine water. It will cover key aspects of mine water geochemistry and the management as well as treatment of polluted mine water. The lecturer will be Dr. Habil Christian Wolkersdorfer, SARChI Chair in Acid Mine Water Treatment and Finnish Distinguished Professor for Mine Water Management.

  • San Juan Mining & Reclamation Conference
    May 2-4, 2018 | Creede, Colorado

    Each year, the conference is hosted in a different San Juan community to highlight the host area's mining heritage and successes in conducting mine remediation and water quality improvement projects. This year's theme is "Planning for Resiliency."

  • 25th Annual Mine Design, Operations & Closure Conference
    May 6-10, 2018 | Fairmont, Montana

    This annual conference offers the latest in mining-related technologies and methods, delivered by industry professionals. It includes a session on Reclamation/Remediation.

  • 2018 ASMR Conference
    June 3-7, 2018 | St. Louis, Missouri

    The 35th Annual Meeting of the American Society of Mining & Reclamation will include sessions on acid mine drainage and reclamation, among others.

  • 2018 PA Abandoned Mine Reclamation Conference
    June 20-21, 2018 | State College, Pennsylvania

    This conference provides a forum for disseminating information and encourages discussion between industry, watershed groups, and decision makers to help further innovations in public policy, abandoned mine reclamation, remediation, and restoration of Pennsylvania's watersheds and communities impacted by abandoned mine drainage and abandoned mine lands.

  • Recycling Metals from Industrial Waste: Colorado School of Mines Annual Short Course
    June 26-28, 2018 | Golden, Colorado

    Recycling Metals from Industrial Waste, now in its 25th year, focuses on current plant practices to convert metal-containing wastes to products. Processors, raw materials, and markets are identified and quantified. Speakers with decades of hands-on experience detail multiple approaches to recycling metals and associated materials - backed up by slides, videos, and the syllabus.

    Particular emphasis is given to combinations of physical, hydrometallurgical, and pyrometallurgical processing, along with associated regulations, to facilitate economical recycling. The presentations are on a practical level, focusing on plant operations, with ample opportunity for interaction by the course participants.

  • 40th Annual National Association of Abandoned Mine Land Programs Conference
    September 9-12, 2018 | Williamsburg, Virginia

    This year the National Association of State Land Reclamationists (NASLR), which will hold it's 46th annual conference in conjunction with NAAMLP, will be harnessing the natural synergies between the two organizations. The conference will feature technical presentations unique to abandoned mine land reclamation and will provide valuable exchanges of issues specific to reclamation specialists.

  • 11th International Conference on Acid Rock Drainage (ICARD)
    September 10-14, 2018 | Pretoria, South Africa

    ICARD features presentations on acid mine drainage and mine water issues relating to active mining and mine closure.

  • Tailings and Mine Waste '18
    September 20 - October 2, 2018 | Keystone, Colorado

    Topics related to the engineering and management of tailings and mine waste will be covered, including case histories, design, operation, and disposal for mine waste management, geotechnical considerations, liners, covers and barriers for waste control, reclamation and remediation of mine impacted sites, oil sands issues, surface water and groundwater management and geochemistry, and policies, procedures and public safety.

 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 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.

Workshop 1 - Evaluating Water Chemistry Predictions at Hardrock Mine Sites
