Acid Rock Drainage (ARD) - Overview of Passive Treatment: What you can use it for and what can it achieve

Watch the Webinar Recording

Passive treatment has been used to address mine drainage (ARD) for the past several decades with a notable expansion of its use around the turn of the millennium. Many passive treatment systems were projected to achieve 15-25 years of operation with expectations of very low, to no maintenance. Over the years, much has been learned about what we can expect from passive treatment. This presentation will emphasize how to characterize mine drainage and take a realistic, stepwise approach to achieving treatment goals. Examples of treatment system performance will be shared to demonstrate passive treatment capabilities with data collected near the mid-life of several systems. Pollutants to be addressed include acidity, iron, manganese, and aluminum.

Timothy P. Danehy, QEP has been involved with the implementation of passive technology since 1996. After co-founding BioMost, Inc. in 1998, he has been responsible for the design of over 100 passive treatment systems located throughout the coal fields of Appalachia and the Tri-State mining district. His experience includes the operation and maintenance of dozens of systems for watershed groups as well as mine operators. Recent work has focused assessment and rehabilitation of large-scale systems constructed over the past two decades. He is co-inventor on several patents related to mine water treatment and his firm has constructed and rehabilitated some of the largest passive systems in Pennsylvania and Oklahoma.

Predicting TDS Release from Appalachian Coal Mine Spoils and Valley Fills

Watch this Webinar Recording

Over the past twenty years, water quality compliance criteria for active Appalachian coal surface mines shifted dramatically from limiting acid-mine drainage (AMD) impacts to concerns related to total dissolved solids (TDS) release. This seminar focuses on a collaborative multi-state (KY, VA, and WV) study to predict and limit regional TDS impacts, particularly from valley fills. Assuming acid-forming material are avoided, relative TDS risk is strongly related to pre-mine weathering extent and rock type, but can be reliably predicted with simple lab pH and SC tests. Our combined results indicate that TDS emissions from most properly constructed valley fills should drop to relatively low levels (< 350 mg/L) with time, but that may take decades following closure.

“Building Better Mine Rock Stockpiles for Effective and Sustainable Outcomes - or - Wouldn’t it Better if…. “The Best” Reclamation Cover System Was One You Didn’t Need”

Watch this Webinar Recording

Mine rock stockpiles (MRSs) represent the substantive percentage of risk for acidity generation, and therefore metal leaching and acid rock drainage (ML-ARD) risk on a mine site; greater than that arising from all other landforms arising from mining activity combined. Status quo in the mining industry is to utilize reclamation cover systems and collection-treatment systems to manage this risk. The result, most often, is unrecognized and underfunded liability during operations and closure. Strategic placement of run-of-mine (ROM) rock within an MRS has far greater influence on an MRS’s hydraulic, geotechnical, geochemical, and geomorphological behavior during operations and closure, as compared to that which can be imposed by a cover system alone. This webinar discusses how we can apply net present value (NPV) to inform reclamation/closure decisions throughout the mine-life cycle to address our industry’s challenge of unrecognized and unfunded liability. This will frame, and focus, on technical content of the webinar in describing, from a closure planning and mine planning perspective, what is a “better” MRS, as well as assessment metrics to define “better,” and indeed, what is “best.”

Innovative Use Cases: Drones for Reclamation Monitoring

Watch this Webinar Recording

Large or remote areas of land are challenging and expensive to monitor for landform stability or ecological parameters using ground-based methods. Drone imagery is becoming a prevalent part of environmental monitoring with more data than ever before available for analysis. Recent developments in computer vision and artificial intelligence, combined with knowledge in ecological characterization, can allow for the analysis of large volumes of rapidly compiled remote sensing data for relevant signals and provide new understanding. For this presentation, we will discuss the state of the science of drones for remote sensing and then present several relevant case studies of successful application of remote sensing and AI technologies for monitoring environmental and reclamation projects.

Mike Rawitch is a geologist and geographer specializing in the implementation of geospatial technologies to optimize environmental problem solving. At Ramboll, his focus is on remotely sensed data analysis, collection and visualization applied to environmental monitoring. Mike’s team at Ramboll uses aerial imagery and image analysis to understand site conditions, reduce uncertainty and help efficiently characterize and monitor environmental sites. Mike is an Interstate Technology and Regulatory Council (ITRC) team member and is a co-author on the ITRC Chapter for Advanced Site Characterization Tools. He is also a certified Federal Aviation Administration (FAA) Remote Pilot, is a senior Unmanned Aerial System (UAS or drone) operator within the Ramboll’s global drone practice group and serves on industry advisory boards at Kansas State University and the University of Kansas for his expertise in UAS.

Reclamation in Teaching

Watch this Webinar Recording

Reclamation sciences are incorporated into undergraduate curricula in various ways, from major requirements to electives, and from in-class to in the field. Teaching reclamation sciences is critical for developing the next generation of reclamationists and engaging in conversation around reclamation pedagogy is critical for continued innovation in teaching. This webinar will feature three academics engaged in teaching reclamation in various contexts and at various institutions. Each instructor will provide an overview of their course, highlighting particularly effective pedagogy, followed by an informal conversation around challenges faced and lessons learned.
