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 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.

Use of Unmanned Aircraft Systems (UAS) in BLM
Brian Hadley, Ph.D., BLM

This presentation details the Bureau of Land Management's (BLM) UAS activities, including an overview of the program objectives, current aircraft, and pilot training requirements. For nearly a decade, BLM has effectively employed UAS technology for a wide variety of natural, cultural, and paleontological resource management applications, including biological surveys (e.g., population counts), dinosaur tracksite and fossil imprint mapping, surveys of abandoned mine lands (e.g., volumetric estimates at CERCLA sites), and production verification for mining operations. Examples of data products generated from UAS platforms include ortho-imagery, digital elevation models, 3D point clouds, and full motion video.

Optimizing Remediation Approaches at Mine Sites: How Understanding Biogeochemical Processes and Modeling Can Guide AMD and In Situ Uranium Treatments
Kate Campbell Ph.D, USGS

This presentation aims to aid viewers to understand fundamental biogeochemical processes at metal-rich sites can improve conceptual and numerical models. Case studies illustrate surface and in situ groundwater treatment approaches with associated laboratory experiments, including acidic, metal-rich waters and uranium-impacted aquifers. Strong links between microbiology, mineralogy, hydrology, and water chemistry are crucial for models development applied to site management.

Brian Hadley is a Senior Photogrammetrist with the Geospatial Section at the BLM’s National Operations Center in Denver, CO. He received a B.A. and M.A. in Geography from the University of California, Santa Barbara, and a Ph.D. in Geography (Remote Sensing) from the University of South Carolina. Before coming to the Bureau in 2013, Brian worked as a GIS manager for the South Carolina Army National Guard (Columbia, SC), and as a remote sensing analyst at NOAA’s National Ocean Service Office for Coastal Management (Charleston, SC). Brian’s work at BLM is primarily focused on the use of traditional aerial and close-range photogrammetry for the mapping/monitoring of natural resources. The BLM Geospatial Section provides remote sensing, photogrammetry, and UAS operation services to BLM staff across all levels of the organization.
