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.

This seminar presents a systematic approach for the evaluation of capture zones at pump and treat systems, and provides an overview of a recently published USEPA document on the topic (EPA 600/R-08/003, January 2008). The target audience is project managers who review those analyses and/or make decisions based on these types of analyses. This course will highlight: the importance of capture zone analysis during ground water remediation, particularly for sites requiring containment; key concepts of capture, such as "target capture zones" and "converging lines of evidence;" and typical errors made in capture zone analysis. Examples will be used to demonstrate key aspects of capture zone analysis. For more information and to register, see htt^v/ciuHtvoia/studia. Demystifying the DMA (Demonstration of Method Applicability) - July 28. The DMA is critical in evaluating and understanding the utility of any real time measurement technology or novel approach at a site. In accordance with Triad's goal of managing decision uncertainty, a DMA provides an initial look at any technology or strategy performance in terms of its ability to meet project decision criteria and guide dynamic work strategies. This presentation will include an overview of the DMA process and provide examples of how DMAs have been structured under Triad projects. Examples are expected to highlight the multitude of activities that can be considered for a DMA TechDirect: July 1, 2008 1 of 5 clu-in.ora/newsletters ------- while demystifying the process and providing a platform to design a DMA for your next Triad project.

This workshop was held April 1 -3, 2008, and was sponsored by EPA's Office of Air Quality Planning and Standards, Office of Research and Development, and Office of Solid Waste and Emergency Response. At the workshop, studies involving the use of differential absorption light detection and ranging systems (DIAL), solar occultation flux (SOF), and Fourier transform infrared spectroscopy (FTIR) techniques at petroleum related facilities in the Houston, TX area and open path techniques for use at other types of facilities were discussed (May 2008, 523 pages).

Biowall substrates are typically low-cost materials (e.g., mulch, compost). The substrates are mixed with common construction materials (e.g., sand, gravel) to prevent compaction and maintain permeability. Amendments can be added to stimulate both biotic and abiotic degradation processes, based on the type of contaminant(s) present and the desired degradation pathway(s) to be stimulated.The technology can be applied in source areas or use groundwater recirculation to capture deeper plumes in an in situ bioreactor configuration (May 2008, 302 pages).

Reduce, Reuse, and Recycle Construction and Demolition Materials at Land Revitalization Projects.Sustainable reuse of brownfield properties includes efforts to reduce the environmental impact by reusing and recycling materials generated during building construction, demolition, or renovation. Typical construction and demolition (C&D) materials include wood, drywall, cardboard, brick, concrete, metal, insulation and glass. There are numerous opportunities to recover and use C&D materials at brownfields and land revitalization sites (June 2008, 8 pages).

The SAGTA / NICOLE Workshop on 3rd March drew together current thinking and approaches, issues of both benefits and costs as well as the perceived gaps and uncertainties that may act as specific challenges to achieving sustainable remediation. Presentations were divided into two themes: defining sustainable remediation and how sustainable development might be better implemented in remediation. Several speakers from NICOLE, SAGTA and English Partnerships provided scene setting viewpoints, with papers from the UK, Austria and Switzerland exploring industry and regulatory in more detail. A series of case studies of decision support approaches and examples of sustainable remediation provided examples of implementation. These two themes of defining and implementing .sustainable remediation, were then explored further in two parallel syndicate sessions to provide conclusions for the meeting.

EPA is partnering with the U.S. Army Corps of Engineers to provide state, tribal, and federal regulators with information about new methods of optimizing groundwater monitoring programs. The training will be held at the EPA Region 9 Office in San Francisco, CA on July 30 and 31, 2008. Responsible parties, federal facility cleanup managers, and EPA have used LTMO methods at more than 100 sites nationwide and are likely to use them at more sites in the future. These methods are used to support decision making regarding optimal location and frequency of groundwater monitoring and to support changes to existing monitoring networks. The training includes 1-day of lectures on a variety of qualitative and quantitative methods, including: the Monitoring and Remediation Optimization System (MAROS); the Geostatistical Temporal-Spatial (GTS) algorithm; and the Three-Tiered Monitoring Network Optimization (MNO) approach. A 4-hour hands-on training session with the MAROS software program will be offered on the second day for a limited number of attendees. While the training is designed primarily for state, tribal, and federal regulators, federal facilities cleanup managers, potentially responsible parties (PRPs), and contractors are welcome to participate at no cost. State and federal regulators will receive registration priority. For more information and to register, see http://www.trainex.ora/ltmo . Call for Poster Abstracts!!
