Revegetation of Mine Wastes in Arid Environments: Linking Above- and Below-Ground Performance - August 12, 2020, 1:00PM-2:30PM EDT (17:00-18:30 GMT). Hard rock mining results in extensive land disturbance due to economic mineral extraction and residual mine waste deposition. Revegetation accelerates reclamation of land disturbed by mining; however, the revegetation of mine waste sites in arid regions of the world has unique environmental challenges due to low water availability and sensitive ecologies. Further complicating the issue is the myriad of wastes that exist. Here we focus on mine tailings, which exhibit a wide range of pH and metal content, as well as waste rock. In this presentation, we will discuss what we have learned over the last decade about how below-ground metrics are related to and can predict revegetation success under a variety of conditions and revegetation approaches. We will present data from legacy and modern waste sites examining both direct planting into mine waste and cap and plant scenarios. We are using these data to identify below-ground metrics that correlate with vegetation establishment patterns and are easy to measure; and then using the identified metrics to develop guidance for prediction of tipping points for vegetation success or failure. An additional outcome of this work is creation of the University of Arizona Center for Environmentally Sustainable Mining which has facilitated a partnership with Arizona copper companies called the Collaborative Industry-University Research Initiative on Revegetation of Mine Wastes. This partnership has enabled both a comprehensive assessment of multiple revegetation strategies under diverse conditions and an open atmosphere wherein results are shared among all partners through annual reports and meetings.

ITRC Integrated DNAPL Site Characterization - August 20, 2020, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The Integrated DNAPL Site Characterization Team has synthesized the knowledge about dense non-aqueous phase liquid (DNAPL) site characterization and remediation acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the guidance to develop and support an integrated approach to DNAPL site characterization, including: identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM); define an objectives-based DNAPL characterization strategy; understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data; and navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps.

ITRC Characterization and Remediation of Fractured Rock - August 25, 2020, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The basis for this training course is the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. By participating in this training class, you should learn to use ITRC's Fractured Rock Document to guide your decision making so you can: develop quality Conceptual Site Models (CSMs) for fractured rock sites, set realistic remedial objectives, select the best remedial options, monitor remedial progress and assess results, and value an interdisciplinary site team approach to bring collective expertise to improve decision making and to have confidence when going beyond containment and monitoring -- to actually remediating fractured rock sites. For more information and to register, see or

ITRC Optimizing Injection Strategies and In situ Remediation Performance - August 27, 2020, 1:00PM-3:15PM EDT (17:00-19:15 GMT). ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) and this associated training course to identify challenges that may impede or limit remedy effectiveness and discuss the potential optimization strategies, and specific actions that can be pursued, to improve the performance of in situ remediation by: refining and evaluating remedial design site characterization data; selecting the correct amendment; choosing delivery methods for site-specific conditions; creating design specifications; conducting performance evaluations, and optimizing underperforming in situ remedies. The target audience for this guidance and training course is: environmental consultants, responsible parties, federal and state regulators, as well as community and tribal stakeholders. This training will support users in efficiently and confidently applying the guidance at their remediation sites. An optimization case study is shared to illustrate the use of the associated guidance document. For more information and to register, see or

ITRC Long-term Contaminant Management Using Institutional Controls - September 3, 2020, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC's Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of ICs. After attending the training, participants will be able to: describe best practices and evolving trends for IC management at individual sites and across state agency programs; use this guidance to improve IC reliability and prevent IC failures, improve existing, or develop new, IC Management programs, identify the pros and cons about differing IC management approaches; use the tools to establish an LTS plan for specific sites; and use the elements in the tools to understand the information that should populate an IC registry or data management system.

Superfund Research Program (SRP) Research Brief 307: Clay Layers May Worsen Arsenic Contamination. Layers of clay are widely thought to protect groundwater aquifers from above-ground contaminants. But according to a new NIEHS Superfund Research Program (SRP) study, these clay layers may play a role in increasing groundwater arsenic contamination. At a site near the village of Baylakandi, Bangladesh, Columbia University SRP Center researchers observed increasing concentrations of arsenic over time in deeper wells, revealing that clay layers rich in organic carbon may enhance arsenic contamination, rather than protect against it.
