EPA's Office of Research and Development's Office of Science Policy and Center for Environmental Solutions & Emergency Response is sponsoring a 4-part virtual workshop series to address characterization, remediation, and response challenges at Superfund and legacy mining and mineral processing sites. Each virtual workshop will include a short lecture by various subject matter experts in their respective fields but will also allow ample time for the presenters to interact with the audience, including time for questions and answers as well as brainstorming and identifying concerns from stakeholders participating in each virtual workshop. If you have a mining reclamation or remediation site, this is the virtual workshop for you! The fourth session will focus on the use of big data at mining sites. Topics include new 3DVA efforts at Superfund sites; fate and transport at watershed scales; and visualization of mining data.
