Book Description
Previous investigations at Travis AFB concluded that groundwater in portions of the Base is contaminated with chlorinated hydrocarbons and petroleum hydrocarbons. The nature and extent of the contamination are described in Remedial Investigation (RI) reports prepared for four operable units (OUs) at Travis AFB. Each OU covers a portion of the Base and encompasses multiple sites. Natural attenuation of contaminated groundwater is a potential remedy considered for the NEWIOU. In the remedy selection process, the Natural Attenuation alternative (Alternative 2) was compared with the No Action alternative (Alternative 1) and the Extraction, Treatment, and Discharge alternative (Alternative 3). In general, sites considered favorable for natural attenuation are those for which "active" remediation (i.e., extraction, treatment, and discharge) may not be cost-effective because of the relatively low concentrations of contaminants, strong sorption of pollutants on soils, and the potential for natural processes to remediate the contaminant plume in a reasonable amount of time while being fully protective of human health and the environment. The NEWIOU Groundwater WOD selected natural attenuation as the interim remedy for one site (LF006) and identified two sites and a portion of five other sites where the selection of the interim remedy has been deferred, but where natural attenuation will be assessed further. More details regarding the relationship of these sites to the Natural Attenuation alternative are provided in the FS, Proposed Plan, and Groundwater IROD. While the nature and extent of contamination at these sites are characterized in the RI reports, data are lacking with respect to natural attenuation. The understanding of natural attenuation has only recently developed to the point where a systematic assessment of the complex processes involved is possible.

Book Description
Test Area North (TAN) at the Idaho National Engineering and Environmental Laboratory (INEEL) is the site of a large trichloroethene (TCE) plume resulting from the historical injection of wastewater into the Snake River Plain Aquifer. The TAN Record of Decision (ROD) selected pump and treat as the final remedy and included a contingency for post-ROD treatability studies of alternative technologies. The technologies still under consideration are in situ bioremediation, in situ chemical oxidation, and natural attenuation. Both anaerobic and aerobic laboratory microcosm studies indicate the presence of microorganisms capable of chloroethene degradation. Field data indicate that TCE concentrations decrease relative to tritium and tetrachloroethene indicating an as yet unknown process is contributing to natural attenuation of TCE. Several methods for analyzing the field data have been evaluated and important limitations identified. Early results from the continued evaluation of the three alternative technologies suggest the combined approach of active remediation of the source area (in situ bioremediation and/or chemical oxidation replacing or augmenting pump and treat) and natural attenuation within the dissolved phase plume may be more cost and schedule effective than the base case pump and treat.
