Abstract:

This report presents the results of a treatability study TS performed by Parsons Engineering Science, Inc. Parsons ES at Building 1212, Fairchild Air Force Base, Washington to evaluate remediation by natural attenuation RNA of dissolved fuel-hydrocarbons in the shallow groundwater. The TS focused on the fate and transport of dissolved benzene, toluene, ethylbenzene, and xylene BTEX in the shallow groundwater system at the site. Residual light nonaqueous-phase liquid LNAPL present within the vadose zone and phreatic soils serves as a continuing source for the dissolved groundwater contamination. There is no evidence of mobile LNAPL at this site. The site history also is summarized in this report. No previous investigations have been conducted at the Building 1212 site to determine the nature and extent of soil and groundwater contamination. Comparison of BTEX, electron acceptor, and biodegradation byproduct isopleth maps for the Building 1212 site provides strong qualitative evidence of biodegradation of dissolved BTEX compounds
