Mining Webinar Series: Successful Implementation of Biologically-Based Passive Remediation Systems

Sponsored by: U.S. EPA, Office of Superfund Remediation and Technology Innovation, Technology Innovation and Field Services Division

Go to Archive

Metal mines at their end of active operations must prepare for the potential long-term treatment of mining-influenced water (MIW). This webinar will highlight how biologically-based passive remediation technologies have been shown to be a cost-effective option for treating MIW, especially mildly- to moderately-impacted waters at low- to moderate-flow rates such as may be found at remote or closed mine sites. Presenters will share an overview of biologically-based passive remediation technologies, their applicability to mining site conditions and illustrate the remedial design and evaluation process with a current treatability study example. In addition, two case study examples of mining sites with operating biologically-based passive treatment systems will be presented: Iron King Mine near Jerome, Arizona, and Garfield Mine near Delta, Colorado.

Michele Mahoney is a Soil Scientist working on issues related to remediation and reuse of contaminated sites within EPA's Superfund program. In order to support practitioners, she researches and reports on knowledge related to treatment technologies for mining sites, use of soil amendments for remediation and redevelopment/reuse, ecological revitalization, ecosystem services, phytotechnologies, and urban gardening. Michele develops and delivers training for the world-renown EPA Clean-Up Information Network (www.cluin.org), particularly a Mining Webinar Series, and topics related to Superfund Redevelopment, Ecological Revitalization, Ecosystem Services, and Phytotechnologies. She also creates and manages content development for the EcoTools and Mining pages on CLU-IN.org.

Michele has worked with EPA for over 20 years. Prior to her current responsibilities, Michele served the Agency as the lead for food waste composting issues and as an environmental fate and ecological risk assessor for pesticide registration. Michele also has experience as a Contractor for EPA and a Laboratory and Field Researcher.

Michele earned a M.S. in Soil Science from the Washington State University, and a B.S. in Agronomy & Environmental Science from Delaware Valley University.
