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 .

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).

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.
