ITRC Radiation Site Cleanup: CERCLA Requirements and Guidance - June 5. The focus of this ITRC training is EPA's guidance for remediating radioactively contaminated sites, which can facilitate cleanups that are consistent with how chemical contaminants are addressed, except where technical differences posed by radiation are addressed. This course also discusses long term stewardship (LTS) challenges related to the large radioactively contaminated sites. This understanding of LTS issues is integral to the cleanup process and decisions made at the radiation sites. For more information and to register, see or .

ITRC Protocol for Use of Five Passive Samplers - June 7.

Soil Remediation, Revitalization, and Reuse: Technical Performance Measures is now available. This CLU-IN section is a tool to assist site project managers in selecting appropriate Technical Performance Measures (TPMs) for evaluating the success (risk reduction) of soil amendments or other in situ technologies used for remediation, revitalization, and reuse of contaminated sites. The database of TPMs and the search engine at the heart of this new tool contain a range of potentially applicable TPMs. This provides site managers the flexibility they need to design the most appropriate testing for their sites while providing consistency and comparability between sites. The database includes a set of "core" TPMs chosen for their ready availability, reasonable cost, and level of standardization, plus supplemental TPMs that could be useful and/or important depending on specific conditions at your site. Users can search the database by using criteria (including the project goal, exposure pathway, and desired performance endpoint) that are appropriate for their sites. The search results provide information about each method that matches the selection criteria, including whether the method is a "core" TPM, comments on issues to consider when using the method, and references for additional information. The TPMs in the database currently focus on metals, and the list is not exhaustive. Users are encouraged to suggest other appropriate tests that should be included. Over time, the matrix also may be expanded to include other types of contaminants. For more information, see .

Triad Implementation Guide (SCM-3). This document was published by the Interstate Technology and Regulatory Council (ITRC). It provides guidance for environmental organizations that want to implement the U.S. Environmental Protection Agency Triad process into their business practices. This document is intended to complement the first Sampling, Characterization, and Monitoring Team document, Technical and Regulatory Guidance for the Triad Approach: A New Paradigm for Environmental Project Management (ITRC 2003). Although this document is written to specifically address issues that may be encountered by a state agency, it should also be helpful to those in other segments of government and in the private sector. Reasons for implementing Triad are discussed, as are myths, potential obstacles, and lessons learned. Challenges and solutions to anticipated issues are discussed. The appendices include an example of an organization attempting to establish Triad as an internal policy. Other appendices include information on legal defensibility, budget and procurement issues, and acceptability of data generated via field methods and considerations dealing with risk assessment (May 2007, 63 pages).

Grand Plaza Site Investigation Using the Triad Approach and Evaluation of Vapor Intrusion (EPA 540/R-07-002). This document provides a detailed report about a field study conducted by EQM/URS on behalf of EPA's National Risk Management Research Laboratory to characterize the subsurface contamination of volatile organic compounds (VOCs) at a Brownfield commercial site. The Triad approach was implemented to characterize the extent of soil, groundwater, and soil gas contamination. These data were used to assess impact on indoor air due to vapor intrusion. Seventy-seven soil samples, twenty-eight groundwater samples, and ten soil-gas samples were collected from Geoprobe(TM) borings and analyzed on-site by USEPA Method SW-846 8265 direct sampling ion trap mass spectrometry (DSTIMS). Additional SW-8260b and TO-15 analyses were performed on approximately 10% of the samples by off-site laboratories. Tetrachloroethylene (PCE), trichloroethylene (TCE) and cis-1,2-dichloroethylene (DCE) were detected in all media with PCE as the prevalent compound (September 2006, 86 pages). View or download at .

Vapor Intrusion and Ambient Air Study Final Results Report: Armen Cleaners, Ann Arbor, Michigan (EPA 542-R-06-010). This report summarizes data collection and results from an investigation at the Armen Cleaners site in Ann Arbor, Michigan. The primary focus of the investigation was to identify issues related to vapor intrusion. This report further provides suggestions and information on data utility, additional data needs, risk assessment, and remedial action for the site. The evaluations and suggestions presented in this report have been developed in accordance with the Triad approach to site characterization and remediation that EPA is promoting. The Triad approach stresses the use of systematic planning, real-time measurement technologies, and dynamic work strategies in the field to expedite environmental data collection and increase the weight of evidence generated to support environmental decision-making throughout the project or site life cycle.

Technology News and Trends (EPA 542-N-06-009). This issue highlights methods for harnessing energy from renewable resources to reduce remediation costs and minimize the environmental footprint left by remediation technologies. These methods currently are used to generate virtually no-cost electrical power for low-energy remediation systems, to "polish" remediation following aggressive baseline technologies, or to serve as baseline technologies addressing moderate contaminant concentrations. Incorporation of renewable energy resources early in remediation planning can significantly reduce long-term cleanup costs and allows site managers to evaluate environmental tradeoffs of potential remedies (May 2007, 6 pages).
