Early on in the planning process, it was recognized that whole-scale removal of the COCs (arsenic, copper, lead, zinc, and cadmium) was impracticable and infeasible.ln situ treatment of soils and wastes, using alkaline amendments to raise pH and immobilize metals, was developed to re-establish vegetation. Methods to assess ecological dysfunction and assign remedial actions, treatability studies and demonstration plots were all developed in the 1980s and 1990s, resulting in remedial actions beginning in the late 1990s. As work is completed, more information was gained from the results. While much of the revegetation work was successful, other areas were not, particularly in those areas close to the former smelters where COC concentrations in soil were much higher. EPA identified phytotoxicity concerns in certain areas during the 2010 Five Year Review. EPA and the responsible party collaboratively conducted a study evaluating plant growth in remediated areas while looking at several factors such as COC levels in soil. This evaluation led to development of a total metal index for soil based on the probable success of reclamation grass species. Using this information, EPA and the responsible party revised the existing vegetation management plan for the site to allow for voluntary remediation to achieve higher levels of cleanup to allow unrestrictive land use (e.g., with no long-term O&M requirements). This represents a "win-win" for the landowner, the responsible party, and the regulatory agencies. This webinar will review the results of over 20 years of remedial activities at the Anaconda Smelter site, and how the knowledge gained from this work has been used to develop a better cleanup that satisfies all party involved.

ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions - June 16, 2015, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Environmental molecular diagnostics (EMDs) are a group of advanced and emerging analytical techniques used to analyze biological and chemical characteristics of environmental samples. Although EMDs have been used over the past 25 years in various scientific fields, particularly medical research and diagnostic fields, their application to environmental remediation management is relatively new and rapidly developing. The ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013) and this companion Internet-based training will foster the appropriate uses of EMDs and help regulators, consultants, site owners, and other stakeholders to better understand a site and to make decisions based on the results of EMD analyses. At the conclusion of the training, learners should be able to determine when and how to use the ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013); define when EMDs can cost-effectively augment traditional remediation data sets; and describe the utility of various types of EMDs during remediation activities.

This guidance document reviews the current knowledge of DNAPLs and their subsurface behavior. Using an integrated site characterization (ISC) approach that emphasizes adequate data resolution to fully characterize a site, this document describes how to align data on contaminant distribution, geology, and groundwater flow at a spatial resolution appropriate to the site-specific remedial objectives. With improving understanding of subsurface contaminant behavior, both existing and new tools and techniques can be used to measure physical, chemical, and hydrologic subsurface parameters to better characterize the subsurface. This document synthesizes the knowledge of DNAPL site characterization and remediation and provides guidance on simultaneous characterization of contaminant distributions, hydrogeology, and attenuation processes to allow for improvements in the following areas: assessment of ongoing contaminant exposures; quantification of contaminant transport, storage, and attenuation patterns; prediction of future exposures that would occur without intervention; prediction of changes in future exposures that would occur in response to remedial actions; and selection and design of remedial actions (May 2015, 381 pages).

Promoting Nanoremediation Using Nanoscale Zerovalent Iron (nZVI): Risk-Benefit and Markets Appraisal, Initial Exploitation Strategy and Consultation. NanoRem (Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment) is a research project, funded through the European Commission's Seventh Framework Programme. NanoRem focuses on facilitating practical, safe, economic and exploitable nanotechnology for in situ remediation of polluted soil and groundwater. Part of the project is to understand the future promise of iron nanoparticles/nanoscale zero valent iron (nZVI) use in remediation as a remediation technology and to understand more about stakeholders thoughts and knowledge of the technology and its future opportunities. NanoRem has recently produced an interim "Risk-Benefit and Markets Appraisal, Initial Exploitation Strategy and Consultation" on the use of nZVI. This short report summarizes NanoRem's initial findings. NanoRem is interested to collect additional opinions from different practitioners and stakeholders about the issues raised in this report and its interim findings. In order to do this NanoRem has created a short questionnaire where they would greatly value your input. View or download the report and complete the questionnaire at: http://www.nanorem.eu/Displavnews.aspx?ID=810 Research Brief 245: Using Lead Isotopes to Identify Sources of Metal and Metalloid Contaminants. By sampling wind-blown dust and aerosol, researchers from the University of Arizona Superfund Research Program have measured airborne metal and metalloid contaminant dispersion patterns from mining operations. While using an existing technique in a new way, the UA SRP researchers measured the extent of soil contamination near a mine and smelter while verifying the use of lead isotope analysis to identify contaminant sources.

Workshop Report: Informal Workshop on Burial and Mobility Modeling of Munitions in the Underwater Environment. The objectives of the informal workshop were to enable SERDP project teams to 1) collaboratively share research progress with peers; 2) identify needs for integration of observations and modeling efforts; 3) comprehend the concerns of DoD site managers; 4) define a pathway forward; and 5) clearly state the product expected to culminate from all relevant project efforts. Quite often, underwater environments can be dynamic locations where munitions are more likely subject to mobility, burial, and re-exposure when compared to terrestrial environments. One of the goals of the burial and mobility modeling aspect of the SERDP Munitions Response (MR) program is the development of predictive models to TechDirect: June 1, 2015 4 of 7 clu-in.ora/newsletters ------- quantify both the short- and long-term behavior of the distribution of unexploded ordnance (UXO) present at each underwater site. These predictive models must be probabilistic in nature such that they not only make predictions, but also simultaneously estimate the uncertainty of the predictions to allow site managers to make the most informed decisions with regards to remediation and risk.This report summarizes the results and discussion from the informal workshop, identifies areas and topics for future research, and may be used as a guide for future proposals (December 2014, 23 pages).
