Phytoremediation and PhytoForensics: Mother Nature can Detect and Mitigate Pollutants…with Elegance - October 10, 2017, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Phytoremediation is the field of looking to use plants to mitigate environmental pollutants and human exposures. As plants are efficient, key components in local and global water, carbon and energy cycles, they can influence pollutant transport and availability in many different ways. In this presentation, methods of using plants to prevent human exposure to pollutants will be presented and discussed so share fundamental concepts and case studies of applications. Novel methods of using plants as environmental sensors will also be presented, known as Phytoforensics. As plants interact actively and intimately with the subsurface environment, new analytical and remote sensing methods have been developed to use plants as biosentinels. Using plants in these roles, leads to some unique challenges when looking at typical measures of efficacy for remediation, and the unique aspects of plants also creates new combinations of benefits where we concurrently gain ecosystem services at the same time we are mitigating potential human exposure or environmental damages. Novel integration of plants in urban design can particularly bring multiple, values to our society. Example applications of these techniques in the Superfund program will also be highlighted.

Adverse Outcome Pathways: Session I - Introduction to the Adverse Outcome Pathway Framework - October 11, 2017, 1:00PM-3:00PM EDT (17:00-19:00 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 first session, U.S. EPA staff will provide an introduction and overview of AOPs and discuss the AOP Knowledgebase, which is designed to house descriptions of the biological mechanisms underlying chemical toxicity in a structured manner. The AOP framework was developed as a means for organizing biological and toxicological knowledge concerning the linkages between molecular-level perturbations of biological systems by stressors and the apical hazards (e.g., disease in humans, reduced survival, growth, reproduction in wildlife) that can result. As such, the AOP framework can help support greater use of mechanistic or pathway-based data in risk assessment and regulatory decision-making. Daniel Villeneuve, Ph.D., will introduce the AOP framework, major principles that guide the development and description of AOPs within the AOP-knowledgebase, and will give examples of some prominent applications of AOPs. Stephen Edwards, Ph.D., will discuss the design of the AOP Knowledgebase and how this supports both AOP development and use. It will include the assembly of AOP networks and their importance when using AOPs. It will also consider methods for developing AOP networks in an automated fashion to complement the expert-driven AOP development efforts within the AOP knowledgebase.

ITRC Groundwater Statistics for Environmental Project Managers - October 12, 2017, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background, compliance, trend analysis, and monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management.

Ecosystem Services Approaches and Tools for Contaminated Site Cleanup - October 24, 2017, 1:30PM-3:00PM EDT (17:30-19:00 GMT). Ecosystem services are nature's contributions to human health and well-being. Examples include areas for outdoor recreation, pollination of food crops, and flood mitigation. In performing our work to protect the environment through contaminated site cleanup, we are learning that we also have the opportunity to protect and revitalize ecosystem services in a measurable way. Join us to learn about efforts by several EPA programs to understand how we may consider ecosystem services in managing contaminated site cleanups. This webinar presents an ecosystem services evaluation framework that resulted from a cross-EPA office collaboration, and summarizes how two quantitative evaluation tools, EPA EnviroAtlas and Service Providing Area (SPA) maps, were piloted at Superfund sites. You will also hear from Superfund site managers who will share insights on how they are considering ecosystem services during cleanup and are implementing innovative approaches for ecological revitalization at their sites. An understanding and quantification of ecosystem services may be helpful to ecological risk assessors and remediation project managers working on sites with existing ecosystems and/or sites with ecological reuse options.

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.

Ecosystem Services at Contaminated Site Cleanups (EPA 542-R-17-004). The Engineering Forum, as one of three technical forums within the U.S. Environmental Protection Agency (EPA) Technical Support Project, developed this issue paper to provide cleanup site teams with information about ecosystem services. Ecosystem services produce the many life-sustaining benefits we receive from nature-clean air and water, fertile soil for crop production, pollination, and flood control. Information about ecosystem services may be considered in the characterization of future land use options or the design of a cleanup that is consistent with anticipated ecological reuse, depending on the regulatory authority of the cleanup program. The concepts and tools described in this issue paper are useful in communicating the positive results of cleanup in addition to achieving the goals of cleanup (August 2017, 15 pages).

TVA Kingston Site Case Study: Revitalization of the Wetlands, Embayments and Emory River (EPA 542-F-16-003). In December 2008, a dike containing about 20 million cubic yards of coal ash from power plant operations failed and released over 5 million cubic yards of coal ash into the Emory River and adjacent land. The spill had significant effects on the community and environment. Aquatic organisms and shorelines were buried in coal ash. Cleanup was needed to ensure the protection of human health and the environment. The cleanup process considered ecological revitalization of the site and surrounding area as an integral part of all response activities. A team of biologists, landscape architects, and engineers worked together to integrate plantings and ecological aspects as components of the cleanup activities. An ecosystem was created by planting a mosaic of forested, scrub-shrub, and emergent wetland plant communities, as well as native trees and seeds in disturbed areas. Today, there are frequent bird sightings at the site, including white ibises, cattle egret, and herons (April 2017, 16 pages). View or download at
