Book excerpt: In-well vapor stripping is a groundwater remediation process whereby volatile constituents are transferred from a liquid to a vapor phase while simultaneously inducing groundwater circulation. The purpose of this research was to design and model a solar powered in-well vapor stripping system to remove chlorinated solvents from groundwater using existing or new monitoring wells, and to provide an affordable alternative to conventional remediation technologies. An analytical model was developed and calibrated for a pilot study conducted at a former dry cleaner site. The study found that induced groundwater circulation increased the rate of contaminant transport into the well by about two orders of magnitude and the average effluent concentrations of dissolved tetrachloroethylene and trichloroethylene leaving the treatment system were reduced by about 83% from the source area. The study estimated an initial 0.9-foot radius of influence that would likely increase over time due to diffusion. The results indicate that the system could cost-effectively be used as either a single- or multi-well point technology to reduce and/or remediate the migration of dissolved chlorinated solvents in groundwater.

Available in PDF, EPUB and Kindle. Book excerpt: In-Well Vapor Stripping extracts volatile organic compounds (VOCs) dissolved in groundwater, and removes these contaminants as a vapor. The technology is based on a well within a well design. Groundwater is recirculated by air injected through the central well. VOCs dissolved in groundwater are vaporized and transferred to the flowing air bubbles. The outer well is kept under vacuum where VOC vapors are extracted in the offgas stream. The outer well delivers the offgas stream to the surface for treatment.

Available in PDF, EPUB and Kindle. Book excerpt: This work plan provides the information necessary for drilling, sampling, and hydrologic testing of wells to be completed in support of a demonstration of the in-well vapor stripping system. The in-well vapor stripping system is a remediation technology designed to preferentially extract volatile organic compounds (VOCs) from contaminated groundwater by converting them to a vapor phase. Air-lift pumping is used to lift and aerate groundwater within the well. The volatiles escaping the aerated water are drawn off by a slight vacuum and treated at the surface while the water is allowed to infiltrate the vadose zone back to the watertable.

Available in PDF, EPUB and Kindle. Book excerpt: Tremendous progress has been made in the field of remediation technologies since the second edition of Contaminant Hydrogeology was published two decades ago, and its content is more important than ever. Recognizing the extensive advancement and research taking place around the world, the authors have embraced and worked from a larger global perspective. Boving and Kreamer incorporate environmental innovation in studying and treating groundwater/soil contamination and the transport of those contaminants while building on Fetter’s original foundational work. Thoroughly updated, expanded, and reorganized, the new edition presents a wealth of new material, including new discussions of emerging and potential contaminant sources and their characteristics like deep well injection, fracking fluids, and in situ leach mining. New sections cover BET and Polanyi adsorption potential theory, vapor transport theory, the introduction of the Capillary and Bond Numbers, the partitioning interwell tracer testing technique for investigating NAPL sites, aerial photographic interpretation, geophysics, immunological surveys, high resolution vertical sampling, flexible liner systems, groundwater tracers, and much more. Contaminant Hydrogeology is intended as a textbook in upper level courses in mass transport and contaminant hydrogeology, and remains a valuable resource for professionals in both the public and private sectors.
