Mining Sites Webinar Series
Matching Biochar Characteristics with Metals-Contaminated Soils to Effectively Reduce Metal Bioavailability at Mining Sites - November 7, 2017, 1:00PM-3:00PM EST (18:00-20:00 GMT).
There are approximately 500,000 abandoned mines across the U.S., which pose a considerable, pervasive risk to human health and the environment due to possible exposure to the residuals of heavy metal extraction. Historically, a variety of chemical and biological methods have been used to reduce the bioavailability of the metals at abandoned mine sites. Biochar is emerging as a novel soil amendment for agriculture and environmental applications that can be used to increase soil carbon, adjust soil pH, supply and retain nutrients, reduce heavy metal bioavailability, improve soil water holding and infiltration, sequester carbon, and provide refugia for soil organisms. Biochar is a charcoal-like, carbon-rich, porous byproduct of thermal pyrolysis or gasification. What makes biochar unique is that its properties are tunable, meaning that they can be manipulated or adjusted to optimize the benefits of using it as a soil amendment. It has the potential to complex and immobilize heavy metals to reduce bioavailability in situ. Simultaneously, biochar can improve soil conditions for plant growth and promote the establishment of a soil-stabilizing native plant community to reduce offsite movement of metal-laden waste materials. Because biochar properties depend upon feedstock selection, pyrolysis production conditions, and the activation procedures used, they can be designed to meet specific remediation needs and specific soil remediation situations. However, techniques are needed to optimally match biochar characteristics with metals contaminated soils to effectively reduce metal bioavailability Ongoing research at Formosa Mine in Oregon and other sites to immobilize heavy metals from tailings and revegetate the soil will be presented.

ITRC Long-term Contaminant Management Using Institutional Controls - November 14, 2017, 1:00PM-3:15PM EST (18:00-20:15 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.

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - November 16, 2017, 1:00PM-3:15PM EST (18:00-20:15 GMT). Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. The ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and this associated Internet-based training provides regulators and practitioners with consensus information based on empirical data and recent research to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

Adverse Outcome Pathways: Session II - Assembling and Assessing AOP Information - November 29, 2017, 1:00PM-3:00PM EST (18:00-20:00 GMT). The NIEHS Superfund Research Program (SRP) is hosting a seminar series focused on adverse outcome pathways (AOPs), which are structured ways to represent biological events leading to adverse health effects. In the second session, presenters will discuss the development of AOPs and how they may be used to support hazard and risk assessment. Carole Yauk, Ph.D., will briefly review common AOP development principles, including identifying key events, and assembling and weighing the evidence to support key event relationships and the overall AOP. A case study will then walk through development of one AOP using the AOP wiki. Using alkylation of DNA as the molecular initiating event, subsequent key events that are measurable and essential will be identified. Key event relationships will be identified and evaluated by assessing the dose, incidence and temporal relationships among the events. The essentiality of each event to the adverse outcome, heritable mutations, will be assessed and the empirical evidence supporting the AOP, and any uncertainties, will be evaluated. Ed Perkins, Ph.D., will discuss efforts to merge the AOP's simple framework for linking effects to a regulated outcome with more biological pathways and measurements such as omics that try to capture the complexity of biology in order to support hazard and risk assessment. Examples will be given on how 'omics and other data can be used in the context of AOPs to assess chemical mixture impacts and how in vitro or in vivo data can be used to determine the likelihood of an AO occurring (e.g. Bayesian AOP networks and mechanistic qAOPs). The AOP framework provides a logical mechanism based structure for formalizing and visualizing the molecular intersection between chemical and nonchemical stressors. However, the impact and relevance of biomedical research public health protection from chemical and nonchemical exposures depends both on the understanding of mechanisms embedded in the AOP framework, and how exposures themselves affect those mechanisms and the likelihood of adverse outcomes. Justin Teeguarden, Ph.D., will introduce similar frameworks for organizing exposure information (like the aggregate exposure pathway (AEP)) and discuss how they can provide critical information about the magnitude of the stress and key information about how environmental concentrations can be related to human exposures. He will also discuss how exposures in studies conducted in vitro or an animal models can be related to human exposures. For more information and to register, see

Investigative Strategies for Lead-Source Attribution at Superfund Sites Associated with Mining Activities. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites (October 2017, 112 pages). View or download at

Superfund Research Program Research Brief 274: Endophytes Help Poplar Trees Clean Up TCE on Superfund Site. Poplar trees can capture and remove trichloroethylene (TCE) from the soil and degrade it. Now, a method using endophytes, symbiotic microbes that live within a plant, has been successfully shown to boost the speed and effectiveness of this natural degradation process. Researchers led by Edenspace Systems Corporation, a Superfund Research Program (SRP)-funded small business, conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a microbial endophyte to clean up TCE-contaminated groundwater. TCE is a known human carcinogen that is widely used as a metal degreasing agent and has been found in groundwater at many military and Superfund sites. After inoculating poplar trees with a specific endophyte strain, the researchers successfully showed that the endophyte-assisted poplars quickly and effectively removed TCE, decreasing concentrations in groundwater from 300 to 5 micrograms per liter.
