Zero Valent Iron Injection Tool. Zero valent iron (ZVI) is a strong reducing agent. It has been used successfully in numerous in situ applications to address chlorinated organic, metal, and explosive compounds (including perchlorate) in contaminated groundwater. ZVI is suited both for injection directly into source zones and for placement along a permeable reactive barrier as a groundwater containment remedy. This training tool focuses on ZVI injection for treating chlorinated solvents. ZVI can be injected in a variety of sizes, media, and methods. Alternative injection sizes include micron or nanoscale ZVI (nZVI). Alternative media include ZVI contained in an emulsified oil (EZVI) or with other iron-carbon combinations (e.g., EHC®; ABC®) to stimulate anaerobic biodegradation. Alternative injection technologies include pressurized nitrogen gas or water as carrying fluids to help the iron powders disperse into the subsurface. ZVI technology has grown and progressed in terms of its use, regulatory acceptance, application methods, and reactive media options. This Web tool is designed to assist Navy remedial project managers in the development and implementation of effective ZVI injection applications. The site uses graphic illustrations to demonstrate the use and behavior of ZVI in the subsurface. Users can: learn about the scientific concepts related to the use of ZVI and the types of ZVI media available for injection, understand the different injection methods used to deliver ZVI to the subsurface, understand which factors influence the applicability of the ZVI technologies, and benefit from the lessons learned during ZVI use at other sites.

DCE/VC Stall Tool. The ability of microorganisms to transform chlorinated solvents to innocuous end products enabled the development of in situ bioremediation as a remedial strategy; however, complete dechlorination of perchloroethene (PCE) and trichloroethene (TCE) to innocuous end products (e.g., ethene and ethane) is not always observed. When the reductive dechlorination process is incomplete, levels of dichloroethene (DCE) and/or vinyl chloride (VC) can build up over time in groundwater. This process is referred to as DCE/VC stall, and it can limit the ability of a bioremediation approach to meet cleanup goals and obtain site closure. The purpose of this training tool is to provide remedial project managers with the information necessary to recognize DCE and/or VC stall. A video graphic can be played that explains reductive dechlorination of PCE and TCE to DCE, VC, and ethene. This tool also explores the biological and/or environmental causes of DCE/VC stall, along with potential solutions. Reductive dechlorination of PCE and TCE to DCE appears at most sites where the redox potential in the aquifer is sufficiently reducing (e.g., iron to sulfate reduction), but at some sites, conditions for complete reductive dechlorination of PCE or TCE to ethene are not present, and degradation stalls at DCE and/or VC. Three basic requirements must be met to form a complete reductive dechlorination pathway: sufficient electron donor (a fermentable carbon source), appropriate redox potential (strongly reducing conditions) in the aquifer, and microbial communities capable of complete dechlorination of PCE to ethene.
