Treatment of Heavy Metals and Elimination of Sulfur with a Novel Sulfate Reducing Permeable Reactive Barrier Containing ZVI - August 27. Acid mine drainage and acid rock drainage contain sulfuric acid together with heavy metals. Biological treatment often relies on sulfate reducing bacteria, which use organic electron donating substrates to enable bacteria to reduce sulfate to sulfide. Subsequently, sulfides precipitate heavy metals. However, excess sulfides are released from the treatment system, so the process is not very effective in removing sulfur. Excess sulfides have oxygen demand, are corrosive and malodorous. A process developed at the University of Arizona uses zero valent iron (ZVI) either alone or mixed with organic substrates. The main advantage of using ZVI is that ferrous iron (Fe2+) released from its corrosion will precipitate sulfides formed by sulfate reduction, thereby avoiding the discharge of excess sulfides from the barrier system. For more information and to register, see .

Using High-resolution Piezocone to Determine Hydraulic Parameters and Mass Flux Distribution - August 27. This seminar will cover the results of an ESTCP-funded ( demonstration of the use of the high-resolution piezocone direct push sensor probe to determine direction and rate of ground water flow in three dimensions. Field hydraulic measurements can be used to determine seepage velocity distributions through interpolation methods recently incorporated into Groundwater Modeling System. Probe data comprised of soil type and co-located hydraulic information is particularly amenable to innovative data fusion based interpolations available through the modeling platform. Following chemical concentration data collection, these innovative data processing approaches allow for the determination of flux distributions at resolutions and spatial configurations never before available. Field scale data collection, interpolation, and modeling results will be presented and discussed. The final technical report for the ESTCP demonstration can be found at For more information and to register, see .

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems - September 11 and October 8.

In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3). This publication systematically lays out the technical and related regulatory considerations for in situ bioremediation (ISB) of chlorinated ethene dense DNAPL source zones, providing information related to site characterization requirements, treatment system application and design criteria, process monitoring, and process optimization. The ability of ISB technology to enhance the dissolution and desorption of nonaqueous-phase contaminants to the aqueous phase, where they can be degraded by the microbial population, depends on the spatial distribution of DNAPL mass in the subsurface (e.g., pool/ganglia ratio) and the ability to deliver amendments throughout this architecture (June 2008, 138 pages).

User's Guide to the Collection and Analysis of Tree Cores to Assess the Distribution of Subsurface Volatile Organic Compounds. Analysis of the volatile organic compound content of tree cores is an inexpensive, rapid, and simple approach to examining the distribution of subsurface volatile organic compound contaminants. The method has been shown to detect several volatile petroleum hydrocarbons and chlorinated aliphatic compounds associated with vapor intrusion and ground-water contamination. Tree cores, which are approximately 3 inches long, are obtained by using an increment borer. The cores are placed in vials and sealed. After a period of equilibration, the cores can be analyzed by headspace analysis gas chromatography. Because the roots are exposed to volatile organic compound contamination in the unsaturated zone or shallow ground water, the volatile organic compound concentrations in the tree cores are an indication of the presence of subsurface volatile organic compound contamination. Thus, tree coring can be used to detect and map subsurface volatile organic compound contamination. (July 2008, 72 pages). View or download at .

Approach to Vapor Intrusion at Contaminated Dry Cleaner Sites: A Survey of Member States. Contaminant movement into buildings due to vapor migration from volatile organic chemical (VOC) contamination in soil and groundwater has become a significant concern to the public, business and regulatory agencies. Dry cleaning operations use a number of VOCs that, if released to the soil and groundwater, can lead to vapor migration into buildings and pose a health threat to people. This paper summarizes responses to a short survey conducted in 2007 regarding how State Coalition for Remediation of Drycleaners (SCRD)-represented states approach vapor migration investigation, mitigation, and site closure at contaminated drycleaner properties. The survey is intended to begin a dialogue regarding state approaches to vapor migration at drycleaners (August 2008, 10 pages). View or download at .
