Hydrogeologic and Water Quality Conditions, South Tank Farm Plume, Rocky Mountain Arsenal.
Abstract
The purpose of this report is to present an updated, more comprehensive characterization of the distribution of contaminants in the South Tank Farm Plume (STFP) for developing and evaluating alternative technologies under the IRA proposed by Shell. In addition to providing the results of the Spring 1990 field investigation, information from previous field and laboratory investigations (i.e., 1988 and 1989) is included to evaluate the significance of biodegradation in controlling the distribution and concentration of STFP contaminants. The STFP is located in the southern half of Sections 1 and 2 on the RMA (Figure 1). It is defined as the composite plume of benzene, toluene, xylene, bicycloheptadiene (BCHPD), and dicyclopentadiene (DCPD) dissolved in groundwater in the uppermost water-bearing zone (WBZl) and migrating from a plume of light non-aqueous phase liquid (LNAPL) near Tank 464A toward Lake Ladora and Lower Derby Lake. The constituents of the STFP are those present in the LNAPL plume which is the primary source of the dissolved plume. those present in the LNAPL plume which is the primary source of the dissolved plume.
