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.

This book was released on 2012-04-23 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is meant to provide the practitioner with information on the natural mixing processes occurring in aquifers as well as to describe basic strategies that can be implemented to enhance mixing in particular cases. For example, when it comes to mixing miscible liquids, one can speed up mixing in the formation by manipulating the flow such as through the use of recirculation wells. Furthermore, much of the mixing can be achieved partially within recirculation wells themselves, where contaminated water is admixed with additives, volatile products may be removed through a vapor mass exchanger, etc. Thus, adding mixing wells can significantly increase the performance of the delivery and mixing system and speed up the process of remediation.
