This webinar is part of a series featuring presentations delivered at the May 2017 Federal Remediation Technologies Roundtable Meeting. This meeting focused on the characterization and treatment of heavy metals at mining sites. More information about the meeting can be found at https://frtr.gov/meetings1.htm. This webinar will focus on techniques that can be implemented for site characterization and modelling. Two techniques will be presented in this webinar: (1) Best practices for monitoring and modeling to understand fundamental biogeochemical processes at metal-rich sites in order to improve conceptual and numerical models; and (2) Use of unmanned aircrafts to conduct biological surveys at mining sites.
