Abstract:A research and demonstration project was completed to evaluate the viability of permeation dispersal as a delivery method for delivering treatment agents to enable in situ remediation of contaminated low permeability media soils. This report describes field-scale testing using unconfined test cells established at the Clean Test Site (CTS) at the DOE Portsmouth Gaseous Diffusion Plant near Piketon, Ohio. At this site a commercially available multi-port injection system (MPIS) was used to deliver contrasting agents into a silty clay deposit. A companion report describes laboratory studies completed at the Colorado School of Mines where intact soil cores collected from the CTS were injected with two chemical oxidants (hydrogen peroxide and potassium permanganate) (see Urynowicz and Siegrist, 2000).
