ITRC Mining Waste Treatment Technology Selection - December 12, 2013, 2:00PM-4:15PM EST (19:00-21:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mining Waste Technology Selection site 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 Mining Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

Using GIS Tools to Analyze, Compute, and Predict Pollution, Session III - Community Engagement - December 13, 2013, 1:00PM-3:00PM EST (18:00-20:00 GMT). In the first presentation, Andy Larkin will discuss how he is integrating fine particulate matter, coarse particulate matter, and ozone air pollutant data into models for the state of Oregon that use Androids and iPhones to make personal and easy to understand air quality predictions. The predicted pollutant concentrations at smartphone locations are displayed on phones as interactive Google maps and graphs, and users are warned if predicted concentrations within 10km exceed custom set warning levels. The predicted pollutant levels at all participant locations are anonymously collected and used to create 3D exposure projection maps for the entire sampling population. In the second presentation, Lex van Geen, Ph.D., will illustrate how field kits could play a much greater role in reducing community exposure to contaminated water or soil. The health risk of human exposure to certain contaminants is often spatially highly variable. This is the case for groundwater that is naturally contaminated with arsenic in many shallow aquifers across South and Southeast Asia, and for soil contaminated with lead from mine tailings. Highly localized knowledge of contaminants from field kits can drastically reduce exposure at a relatively low cost, where laboratory analyses of contaminated water or soil and sensitive field instrumentation are not available.

ITRC Biochemical Reactors for Mining-Influenced Water - December 17, 2013, 2:00PM-4:15PM EST (19:00-21:15 GMT). Mining influenced water (MIW) includes aqueous wastes generated by ore extraction and processing, as well as mine drainage and tailings runoff. MIW handling, storage, and disposal is a major environmental problem in mining districts throughout the U.S and around the world. Biochemical reactors (BCRs) are engineered treatment systems that use an organic substrate to drive microbial and chemical reactions to reduce concentrations of metals, acidity, and sulfate in MIWs. The ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013) and this associated Internet-based training provide an in-depth examination of BCRs; a decision framework to assess the applicability of BCRs; details on testing, designing, constructing and monitoring BCRs; and real world BCR case studies with diverse site conditions and chemical mixtures. At the end of this training, you should be able to complete the following activities: describe a BCR and how it works; identify when a BCR is applicable to a site; use the ITRC guidance for decision making by applying the decision framework; improve site decision making through understanding of BCR advantages, limitations, reasonable expectations, regulatory and other challenges; and navigate the ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013).

CEC Training for OSCs...Community Engagement and Communication Tools for the OSC - December 18, 2013, 1:30PM-3:30PM EST (18:30-20:30 GMT). OSCs are challenged to be well versed in many technical and regulatory aspects of the environmental field. One of the regulatory aspects is the requirement for community involvement as specified in the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The NCP outlines specific activities, deliverables and timelines that must be followed during a given removal action. In addition to the required community involvement activities, there are many useful and timely activities that an OSC can engage in to support their removal action and avoid miscommunication and confusion between the agency and the public. This two-hour webinar provides practical information and tools including: take-home handouts outlining the specific requirements for community involvement as set forth in the NCP, a discussion on the development of an Administrative Record and public notifications, lessons learned: a community engagement case study, and useful tips for developing presentations and communicating information.

Superfund Remedy Report, Fourteenth Edition (EPA 542-R-13-016). The Superfund Remedy Report (SRR), Fourteenth Edition, was published by the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) in November 2013. The SRR 14th Edition summarizes remedy decisions back to 1982 with a focus on the analysis of Superfund remedial actions selected from fiscal years (FY) 2009 to 2011. The report includes remedies selected in 459 decision documents (Records of Decision [RODs], ROD amendments, and Explanations of Significant Differences with changes to remedy components) signed in this three-year period. The SRR compiles data on overall remedy selection and remedies for source materials (such as soil and sediments), groundwater, surface water and air related to vapor intrusion. This edition of the report, for the first time, presents a detailed look at sediment remedies and an analysis of vapor intrusion remedies. The report also analyzes media and contaminants for sites under investigation with planned RODs. The online version includes downloadable appendices that summarize all the remedy components selected for sources and groundwater in each individual decision document (November 2013, 139 pages). View or download at http://clu-in.org/techpubs.htm .

Optimization Review: Naval Base Kitsap OU-1, Keyport, Washington (EPA 542-R-13-009). The document discusses the optimization review performed at the Naval Base Kitsap OU-1 in Keyport, Washington. The Navy and EPA agreed to work collaboratively to conduct an optimization review of OU-1 to evaluate potential options for improving remedy performance. The review focuses on OU-1, with emphasis on addressing the VOC contamination (August 2013, 71 pages). View or download at http://clu-in.org/techpubs.htm .

Soil Vapor Extraction System Optimization, Transition, and Closure Guidance. Soil vapor extraction (SVE), a prevalent remediation approach for volatile contaminants in the vadose zone, may exhibit a diminishing rate of contaminant extraction over time due to diminishing contaminant mass, and/or slow rates of removal for contamination in low-permeability zones. Upon indications of a diminished contaminant removal rate, SVE performance needs to be evaluated to determine whether the system should be optimized, terminated, or transitioned to another technology to replace or augment SVE. The guidance presented in a new report specifically addresses the elements of this type of performance assessment. A stepwise approach is presented for gathering information and performing evaluations to support SVE remedy decisions. Steps include revisiting the conceptual site model, considering relevant information, quantifying the impact of remaining vadose zone contaminant sources on groundwater, and integrating the assessment outcomes into a decision logic approach to addressing optimization, transition, and closure decisions. This material highlights relatively recent advances in use of mass flux/discharge approaches and includes a calculation tool to facilitate the evaluation process. The Soil Vapor Extraction Endstate Tool (SVEET) is a spreadsheet tool that allows the user to easily enter data and calculate the estimated groundwater concentration for one or more scenarios conforming to the generalized conceptual model described in the report. This software provides a convenient method for the user to apply the calculation procedures described in Appendix C of the guidance report (which also walks through an example calculation). Appendix D of the report provides details about the SVEET software, including system requirements, installation, the user interface, and application of the software (February 2013, 130 pages). View or download at http://bioprocess.pnnl.gov/SVEET_Request.htm .

State-of-the-Science Workshop on Mercury Remediation in Aquatic Environments Archive. The U.S. EPA Region 9 State-of-the-Science Workshop on Mercury Remediation in Aquatic Environments was held on September 26, 2013, in San Francisco, California, and via webinar. The workshop brought together participants and speakers from nongovernmental organizations, academia, private industry, regulatory agencies, the consulting sector and all levels of government (federal, state, local and tribal). They shared the latest information regarding mercury remediation techniques and their effects on levels of mercury in fish tissue and presented a balanced and honest assessment of what is and is not working with respect to remediation. This was driven by concerns resulting from legacy mining activities, aerial deposition and other potential sources of methyl mercury. Archives for the workshop are available, including proceedings, audio and slide recordings of the live event, all presentation materials, instructor contact information, and some additional handouts. View and use at http://www.clu-in.org/conf/tio/hg/ .

Evaluating Matrix Diffusion Effects on Groundwater. A new spreadsheet-based tool helps site managers and consultants determine if matrix diffusion processes will cause "rebounding" of downgradient plume concentrations above remediation goals after plume remediation or isolation is complete. Having this information readily available before a remedy is implemented will assist stakeholders in selecting more appropriate remedies and improving effective risk communication. The tool was developed by GSI Environmental Inc. and Colorado State University with support from ESTCP.
