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.

ITRC Protocol for Use of Five Passive Samplers - June 7. This training
supports the understanding and use of the ITRC Protocol for Use of Five
Passive Samplers to Sample for a Variety of Contaminants in Groundwater (DSP-5,
2007). The five technologies included in this document include diffusion samplers,
equilibrated grab samplers; and an accumulation sampler. The training starts with
information common to all five samples then focuses on each sampler as instructors
describe the sampler and explain how it works; discuss deployment and retrieval of the
sampler; highlight advantages and limitations; and present results of data comparison
studies. For more information and to register, see http://www.itrcweh.org or http://ciu-in.om/studio .
ITRC Risk Assessment and Risk Management: Determination and
Application of Risk-Based Values - June 14. 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

> New Documents and Web Resources
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. Overtime, the
matrix also may be expanded to include other types of contaminants. For more
information, see http://www.clu-in.ora/ecorevitalization .
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). View or download

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. View or

RemTech Proceedings (2002-2006). RemTech is sponsored by the
Environmental Services Association of Alberta (ESAA), a not-for-profit business
association dedicated to building a strong environment industry through leadership in
technology, human resources, quality improvement and market development. All of the
proceedings from the annual Remediation Technologies Symposium (RemTech) are
online. This resource is free and searchable and contains approximately 200 technical
presentation (from the past five years) and case studies all focused on remediation and
a variety of technologies, applications and contaminants. For more information, see

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). View or download at http://clu-in.ora/techpubs.htm .
