ITRC Vapor Intrusion Pathway: A Practical Guideline - July 19. The ITRC
Vapor Intrusion Team developed the ITRC Technical and Regulatory Guidance
document Vapor Intrusion Pathway: A Practical Guideline (VI-1, 2007), companion
document Vapor Intrusion Pathway: Investigative Approaches for Typical Scenarios
(VI-1A, 2007), and this Internet-based training course to be used by regulatory agencies
and practitioners alike. This training course provides an overview of the vapor
intrusion pathway and information on the framework (evaluation process), investigative
tools, and mitigation approaches. The training course uses typical scenarios to illustrate
the process. For more information and to register, see http://www.itrcweh.om or

Phytostabilization of Mine Tailings in Arid and Semi-Arid Environments -
July 25. This seminar is sponsored by the NIEHS Superfund Basic Research
Program (SBRP), in conjunction with the University of Arizona SBRP and EPA Region
9. In arid and semi-arid parts of the world, including parts of the western United States,
mine tailings and their associated contaminants are prone to wind dispersion and water
erosion. These problems are extensive and can persist for decades because these
sites lack normal soil stabilization processes including the establishment of a plant
cover and the associated development of soil structure. These sites can have profound
health and environmental consequences especially for children in nearby communities
or for sensitive riparian or wildlife refuge areas. Dr. Raina Maier, University of Arizona
Dept. of Soil, Water and Environmental Sciences, is investigating phytostabilization - the
establishment of a vegetation cover using the native plants - to minimize dispersion and
erosion processes. For more information and to register, see http://ciu-in.orn/sturtio .

Interim Guiding Principles for Good Samaritan Projects at Orphan Mine
Sites and Transmittal of CERCLA Administrative Tools for Good
Samaritans. This joint memorandum was issued by the U.S. EPA. This guidance is
intended to assist the Regions in the implementation of the Good Samaritan Initiative
and focuses on administrative tools developed under CERCLA. As EPA gains more
experience implementing this Initiative, the Agency may revise this guidance and the
attached administrative tools June 2007, 24 pages). View or download at

From Bench to Backyard: EPA Patents at Work Protecting Human Health
and the Environment. This document was published by the U.S. EPA Office of
Research and Development. The U.S. EPA Federal Technology Transfer Act (FTTA)
Program facilitates the transfer of environmental research and technologies into the
marketplace. This catalog describes some of the innovative ideas that help clean your
air, water and land, and contribute to a healthy environment (December 2006, 20
pages). For further information on the broad spectrum of technologies available for
licensing and further development, please visit http://www.epa.aov/osp/ftta.htm .
Characterization and Fate of Gun and Rocket Propellant Residues on
Testing and Training Ranges: Interim Report 1 (ERDC TR-07-1). This report
was published by the U.S. Army Corps of Engineers Cold Regions Research and
Engineering Laboratory. The objectives of the research described in this report are to
characterize the deposition and accumulation of propellant residues at the various
types of firing points at military firing ranges, develop process descriptors to allow
estimation of environmental transport rates of individual energetic chemicals from these
residues, and collect lysimeter and groundwater monitoring well samples to
experimentally assess off-site transport of residues (January 2007, 226 pages). View

Field Demonstration and Validation of a New Device for Measuring Water
and Solute Fluxes at CFB Borden (ESCTP 0114). This Cost and
Performance Report was published by the DoD Environmental Security Technology
Certification Program (ESTCP). In 2001 ESTCP funded a project (CU-0114) to
demonstrate and validate a new monitoring technology known as the passive flux meter
(PFM). This device provides direct in situ measurements of both subsurface water and
contaminant fluxes. The focus of this project was to demonstrate and validate the PFM
for measuring simultaneously the groundwater and contaminant fluxes in contaminated
aquifers. This report presents results of PFM demonstration/validation from a series of
controlled field experiments conducted at the CFB Borden Demonstration Site in
Ontario, Canada (November 2006, 152 pages). View or download at
http://www.estcp.org/viewfile.cfm?Doc=ER%2D0114%2DFR%2DBorden%2Epdf .
In-Situ Substrate Addition to Create Reactive Zones for Treatment of
Chlorinated Aliphatic Hydrocarbons (ESTCP 9920). This Cost and
Performance Report was published by the DoD Environmental Security Technology
Certification Program (ESTCP). The objectives of the demonstrations were to show the
ability to remediate contaminants in the subsurface over a relatively short time period
and to gather information for estimating long-term treatment effectiveness, life span,
and costs. The results of the demonstrations were used to develop a protocol using
ERD technology at Department of Defense (DoD) facilities (Suthersan, 2002). Also
important in these demonstrations was to show that the degradation of CAHs does not
"dead-end" at undesirable by-products such as cis-1,2-dichloroethene (cis-DCE) and
vinyl chloride (March 2007, 93 pages). View or download at

Institute. It provides guidance to those interested in assessing MtBE natural attenuation,
and those with the responsibility of reviewing such work. This manual is designed to:
Present the basic scientific principles relevant to the evaluation of MtBE natural
attenuation; Develop a framework for assessing the feasibility of incorporating MtBE
natural attenuation into an overall site strategy; Identify those data that can be used to
assess MtBE natural attenuation; Provide a concise technical reference for relevant
chemical properties, analytical methods, and field sampling techniques; Provide
protocols and guidance for data interpretation; and Provide guidance on the
presentation of natural attenuation data/information to facilitate regulatory and other
stakeholder review and acceptance of MNA remedies (May 2007, 186 pages). View

Environmental Information Management Systems (EMIS), Irvine, CA,
August 22. This event is sponsored by the Groundwater Resources
Association of California. In today's environmental industry, most clients, regulatory
agencies, and consultants use multiple, disconnected systems to store and manage
their environmental information (e.g., e-mail, office documents, intranets, enterprise
applications, analytical tools). Mission-critical information, data, and expertise needed
to make better and more informed decisions are dispersed across multiple silos of
information and data stores, not just enterprise applications. The reality of this situation
has become a key focus as many sites move to closure and long-term
monitoring/stewardship. Having possession and real time access to critical
environmental data has become a necessity. In addition, many companies are facing
greater scrutiny than ever before as shareholders demand accountability and accurate
reporting (Sarbanes-Oxley Act) and environmental liabilities are not exempt from this
requirement. For more information, please visit http://www.grac.org/eims.asp.
