This training familiarizes participants with ITRC's Phytotechnology Technical and Regulatory Guidance and Decision Trees, Revised (Phyto-3, 2009).This document provides guidance for regulators who evaluate and make informed decisions on phytotechnology work plans and practitioners who have to evaluate any number of remedial alternatives at a given site. This document updates and replaces Phytoremediation Decision Tree (Phyto-1, 1999) and Phytotechnology Technical and Regulatory Guidance Document (Phyto-2, 2001). It has merged the concepts of both documents into a single document. This guidance includes new, and more importantly, practical information on the process and protocol for selecting and applying various phytotechnologies as remedial alternatives.

ITRC Mine Waste Treatment Technology Selection - May 19, 2011, TechDirect: May 1, 2011 1 of 5 clu-in.ora/newsletters ------- 11:00AM-1:15PM EDT (15:00-17:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mine Waste Technology Selection site (http://www.itrcweb.ora/mininawaste-auidance/^ to assist project managers in selecting an applicable technology, or suite of technologies, which can be used to remediate mine waste contaminated sites. Decision trees, through a series of questions, guide users to a set of treatment technologies that may be applicable to that particular site situation. Each technology is described, along with a summary of the applicability, advantages, limitations, performance, stakeholder and regulatory considerations, and lessons learned. Each technology overview links to case studies where the technology has been implemented. In this associated Internet-based training, instructors provide background information then take participants through the decision tree using example sites. Project managers, regulators, site owners, and community stakeholders should attend this training class to learn how to use the ITRC Web-based Mine Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints.

Community Engagement Activities in Native American Communities - May 23, 2011,1:00PM-3:00PM EDT (17:00-19:00 GMT). Dr. Anna Harding and Dr. Barbara Harper of Oregon State University will provide a seminar entitled "Addressing Tribal Exposures to Polycyclic Aromatic Hydrocarbons (PAHs) and Building Tribal Capacity though a Tribal-University Partnership." Their seminar focuses on the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) in Oregon and other tribes in the United States who may be at increased risk of disease due to cumulative PAH exposures from traditionally smoked foods, air exposure from traditional smoking of foods, and ambient air pollution. Their work served to build tribal capacity and establish a Tribal Advisory committee, IRB protocols and material and data sharing agreements, and culturally appropriate activities focused on tribal needs. Dr. Jim Shine and Dr. Laurel Schaider of Harvard University will also present a seminar entitled "Fate and exposure studies of metals in rural Oklahoma: Engaging communities." For the last seven years, Dr. Shine and Dr. Schaider conducted studies in rural northeastern Oklahoma involving heavy metals associated with mine waste and mercury exposure among subsistence and recreational fishers. Through these research activities, proactive engagement with community groups, Native American tribes, and state and federal agencies enhanced the quality and relevance of the research and promoted greater trust among all groups.

Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators can use to objectively assess, design, monitor, and optimize ISB treatment of DNAPL source zones.

The U.S. Environmental Protection Agency (EPA) Principles for Greener Cleanups outline the Agency's policy for evaluating and minimizing the environmental "footprint" of activities undertaken when cleaning up a contaminated site. Use of the best management practices (BMPs) identified in EPA's series of green remediation fact sheets can help project managers and other stakeholders apply the principles on a routine basis, while maintaining the cleanup objectives, ensuring protectiveness of a remedy, and improving its environmental outcome. Use of renewable energy resources provides a significant opportunity to reduce the environmental footprint of activities conducted during investigation, remediation, and monitoring of hazardous waste sites. Substitution of energy from fossil fuel resources with energy from renewable resources is a primary approach for addressing energy as one of the five core elements of green remediation strategies. In turn, lower consumption of fossil fuel will reduce emission of greenhouse gases (GHG) as well as particulate matter and other air pollutants (April 2011, 8 pages).

EPA's new factsheet on urban gardening is now available. You will find information on common contaminants that can be found in urban soil, ways to identify contaminants and reduce exposure, improving soils and growing plants in mildly contaminated soil, and additional resources and technical assistance (Spring 2011,12 pages).

New Triad profiles have recently been added to the User Experiences section of the website. These profiles are concise summaries of successful Triad projects and are backed by a database that can be searched using various criteria such as contaminant, remedial phase, and technology category. Triad is an innovative approach to data collection and decision-making for hazardous waste site characterization and remediation, and the U.S. Environmental Protection Agency's Triad Resource Center Website (http://www.triadcentrai.oraA is a central location for information about the Triad Approach. The website also offers a wide range of information about the use of the Triad including access to the Triad Community of Practice (CoP), Triad technical resources and guidance, and user experiences on the use of Triad at federal and private sites.

TechDirect: May 1, 2011 3 of 5 clu-in.ora/newsletters ------- Focused Review of Specific Remediation Issues: An Addendum to the Remediation System Evaluation for the Homestake Mining Company (Grants) Superfund Site, New Mexico, Region 6 (EPA 542-R-11-002). The current evaluation of the remediation efforts at the Homestake Mining Company (Grants) Superfund site has been conducted on behalf of the US EPA by the US Army Corps of Engineers Environmental and Munitions Center of Expertise. The evaluation is intended to supplement the previous Remediation System Evaluation (RSE) conducted for the site by Environmental Quality Management (EQM, 2008). Specific issues remaining from the RSE, as identified in the Scope of Work, have been addressed through data analysis and conceptual design (March 2011, 428 pages).

Researchers from the Dartmouth Toxic Metals Research Program have created a 10-minute video for the general public on the subject of arsenic. Funded by the National Institute of Environmental Health Sciences Superfund Research Program, the film brings home findings of research on arsenic in well water by identifying high-concentration areas in New England and offering pointers for residents relying on wells for their drinking water. To educate residents about health problems associated with arsenic and what they can do to protect themselves, Dartmouth provides links to additional information from EPA and the U.S. Geological Survey, as well as to state agencies that offer well-water testing for as little as $10.

Explore a subset of the publicly-available simulation and data analysis tools that can be used alone or in combination to answer questions such as: Will source remediation meet site goals? What will happen if no action is taken? Should I combine source and plume remediation? What is the remediation timeframe? What is a reasonable remediation objective? The model discussion will focus on the unique features of selected models and how those features can support strategy development. Emphasis will be on REMChlor, a newly released tool that simulates both source and plume remediation. By providing the ability to simulate sites where conditions change in space and time, REMChlor can provide information "equivalent" to the types of output from more sophisticated numerical models.
