Remediation by Natural Attenuation Treatability Study for Operable Unit 5

Abstract

This report presents the results of a remediation by natural attenuation treatability study (RNA TS) performed by Parsons Engineering Science, Inc. (Parsons ES) at Operable Unit 5 (OU5), Hill Air Force Base, Utah to evaluate the use of natural attenuation with long-term monitoring (LTM) as a remedial option for dissolved chlorinated aliphatic hydrocarbon (CAH) contamination and soil contamination at the site was documented during the remedial investigation performed by Radian International (Radian). This TS focused on the impact of dissolved CAHs, primarily trichloroethene (TCE), on the shallow groundwater system at and downgradient from the site. Site history and the results of soil, groundwater, and surface water investigations conducted previously also are summarized in this report. Several lines of chemical and geochemical evidence indicate that, although dissolved CHAs are undergoing biologically facilitated reductive dehalogenation, the occurrence of this process is limited and localized.
