Solar Powered In-Well Vapor Stripping: A Design, Analytical Model, and Pilot Study for Groundwater Remediation

Abstract (Summary)

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.
