Use of SADA for Spatial Analysis - March 9. Spatial Analysis and Decision Assistance (SADA; http://www.tiem.utk.edu/~sada/) is evolving freeware that incorporates tools from environmental assessment fields into an effective problem-solving environment. Robert Stewart, who leads the development of the software at the University of Tennessee, will focus this discussion on using SADA for spatial analysis. This seminar goes beyond the general SADA CLU-IN seminar (archived at: http://www.clu-in.org/conf/tio/sada_081506/) to show the specific capabilities of SADA for making decisions using correlation, interpolation, and probability; and the caveats for using these methods at hazardous waste sites.

Nanotechnology - DNAPL Remediation - March 15. The Superfund Basic Research Program (SBRP), in collaboration with the Environmental Protection Agency (EPA), presents "Nanotechnology - DNAPL Remediation." In the last decade, the potential to use nanoparticles (particles <100nm in size) for environmental remediation has attracted much attention, particularly to address the challenging scenarios encountered with Dense Non-Aqueous Phase Liquid (DNAPL) contamination. This seminar will explore both the theoretical potential and practical challenges associated with the application of nanoscale particles for in situ remediation of DNAPLs. Matt Hull (Luna Innovations, Inc.) and Peter Vikesland (Virginia Tech) will present "Magnetite Nanoparticles for Remediation of Contaminated Groundwater." As part of their EPA SBIR collaboration, they have developed stabilized suspensions of nanoscale magnetite (Fe3O4) particles for the remediation of groundwater contaminated with carbon tetrachloride (CT). Greg Lowry (Carnegie Mellon University) will present "Functionalized Reactive Nanoscale Fe0 (NZVI) for in situ DNAPL Remediation: Opportunities and Challenges." Dr. Lowry will discuss the potential of surface-functionalized reactive Fe0 nanoparticles (NZVI) to overcome some of the challenges of DNAPL remediation. This is the third seminar in the Risk-e-Learning Series "Nanotechnology - Applications and Implications for Superfund." For more information and to register, see http://clu-in.org/studio .
ITRC Risk Assessment and Risk Management: Determination and Application of Risk-Based Values March 27. This training course describes the development and application of risk-based screening values. The first module provides a review of key risk assessment concepts related to risk management. The second module focuses on the process by which risk-based levels are derived in different states. The third module examines the application of risk assessment to remediation operations in two case studies providing examples of how risk assessment has actually been implemented, based upon research and case studies conducted by the ITRC Risk Assessment Resources team. This training course describes a number of the reasons behind variations in risk-based screening values and their use in risk management.

New Documents and Web Resources
Nanotechnology White Paper (EPA 100-B-07-001). Nanotechnology presents new opportunities to improve how we measure, monitor, manage and minimize contaminants in the environment. New generations of nanomaterials will evolve and with them new and possibly unforeseen environmental issues. The purpose of this White Paper is to inform EPA management of the science issues and needs associated with nanotechnology, to support related EPA program office needs, and to communicate these nanotechnology science issues to stakeholders and the public (February 2007, 132 pages).

Emerging Nanotechnologies for Site Remediation and Wastewater Treatment. This document was prepared by Katherine Watlington, a National Network of Environmental Management Studies (NNEMS) grantee, under a fellowship from the U.S. Environmental Protection Agency. This paper seeks to provide a holistic view of the state of the science of nanotechnology. Both the commercialized nanotechnology products and many of the technologies being researched in academia are discussed. Attention is given both to the research itself as well as the remedial capabilities. The toxicity and safety concerns of the individual technologies are also briefly outlined as are the overall toxicity concerns related more generally to the field of nanotechnology. Finally the current state of regulation is addressed (August 2005, 55 pages). View or download at http://clu-in.org/techpubs.htm.
Innovations in Site Characterization Case Study: The Role of a Conceptual Site Model for Expedited Site Characterization Using the Triad Approach at the Poudre River Site, Fort Collins, Colorado (EPA 542-R-06-007). This case study examines how systematic planning, an evolving conceptual site model (CSM), dynamic work strategies, and real time measurement technologies can be used to unravel complex contaminant distribution patterns and design a remedy at the Cache La Poudre (Poudre) River site. The investigation and design of the remedy involved a former burn landfill, hydrocarbon fuel contamination, and mobile manufactured gas plant (MGP) coal tar waste. The remedy was driven by recreational reuse and proximity to the Poudre River. The remedy involved pathway elimination and stream restoration in a location central to the City of Fort Collins, Colorado (February 2007, 144 pages).

Updated CLU-IN Vendor Support Area. The US EPA Technology Innovation Program announces the release of the newly revamped Vendor Support site, created to provide technology developers and vendors with tools to help advance technologies through all stages of product development from bench scale to full commercialization. The resources collected for this site cover a broad range of topics that include business planning, marketing, financing, and technical issues. Topics are organized into six sections arranged, approximately, in the order in which they are encountered in developing and commercializing a technology. Each section addresses a particular group of activities that lead to the advancement of a technology from the germination of an idea to research, development, testing, and finally to commercial application.

CL:AIRE Technical Bulletin 5: The Use of Geophysical Investigation Techniques in the Assessment of Contaminated Land and Groundwater. This bulletin describes the use of
geophysical investigation techniques in the assessment of contaminated land and groundwater in the United Kingdom (January 2007, 4 pages).
CL:AIRE Technical Bulletin 12: Statistical Assessment of Contaminated Land: Some Implications of the Mean Value Test (Technical Bulletin 12) Statistical methods are commonly used to guide decision-making in many regulatory contexts. For the assessment of potentially contaminated land, it is common practice to use the Mean Value Test approach defined in Appendix A of Contaminated Land Report 7 (DEFRA and Environment Agency, 2002). This bulletin suggests alternative techniques to reduce the risk of underestimating the true 95% Upper Confidence Limit of the sample mean (November 2006, 4 pages).
