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.

Upcoming Live Internet Seminars
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.
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.

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).

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).

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).

Technical Protocol for Evaluating the Natural Attenuation of MtBE (API Publication 4761).
This document was published by the American Petroleum 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).

Monitoring and Measurement for the 21st Century.
The EPA 21M2 website publishes a quarterly literature search for EPA identified monitoring need areas.
These need areas include DNAPL characterization techniques; monitoring mining waste sites; sensor technology development; vapor intrusion monitoring methods; test methods for dioxin, cyanide, mercury, pesticide, perchlorate, MTBE, and emerging contaminants; and remote sensing for a variety of applications.
The most recent quarterly search was posted to the website in June (64 pages).
The June search contains the most recent citations to the literature search database which contains thousands of citations and abstracts on these and other topics.
To access the June quarterly literature search and the database, see http://clu-in.org/programs/21m2/ .

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.
