    Argonne National Laboratory has modeled the groundwater flow in the area of the Twin Cities Army Ammunition Plant (TCAAP) with the Coupled Fluid, Energy and Solute Transport (CFEST) computer code. Argonne performed the modeling for the US Army in support of a remedial action program to capture and treat groundwater contaminated by past activities at TCAAP. This report presents the results of model development and calibration, in which various parameter values were tested to obtain the best match between model-predicted and observed groundwater elevations. After calibration, the model was used to evaluate the efficacy of the extraction well system usedmore » to pump contaminated groundwater to an on-site treatment plant. Argonne found that the wells effectively capture contaminants in the Hillside Sand (Unit 3) aquifer but not in the Prairie du Chien/Jordan (Unit 4) aquifer. 17 refs., 23 figs.« less

    Geophysical studies at Site H of Twin Cities Army Ammunition Plant have delineated specific areas of dumping and waste disposal. Anomalous areas noted in the geophysical data sets have been correlated with features visible in a chronological sequence of aerial photos. The photos aid in dating the anthropogenic changes and in interpreting the geophysical anomalies observed at Site H and across Sunfish Lake. Specifically, two burn cages and what has been interpreted as their surrounding debris have been delineated. The areal extent of another waste site has been defined in the southwest corner of Area H-1. Depth estimates to themore » top of the Area H-1 anomalies show that the anomalies lie below lake level, indicative of dumping directly into Sunfish Lake. Except for these areas along the northwestern shore, there is no evidence of waste disposal along the shoreline or within the present-day lake margins. Magnetic, electromagnetic, and ground-penetrating-radar data have pinpointed the locations of mounds, observable in aerial photos, around the first burn cage. The second burn cage and its surrounding area have also been clearly defined from aerial photos, with support from further geophysical data. Additional analysis of the data has yielded volumetric estimates of the amount of material that would need removal in the event of excavation of the anomalous areas. Magnetic and electromagnetic profiles were also run across Marsden Lake. On the basis of these data, it has been concluded that no large-scale dumping has occurred in or around Marsden Lake.« less

  • This study is to develop a cost-effective and technically practical modernization program for the steam/power plants at the Twin Cities Army Ammunition Plant (TCAAP) while meeting the intent of the Army energy goals of reduced dependence on oil and natural gas. The recommended modernization approach is to provide new coal-fired boilers complete with required auxiliary equipment in an addition to Building 515. One existing oil-fired boiler in Building 515 will be converted to burn coal. This approach will satisfy facility steam requirements from peacetime through mobilization demands. Upon completion of construction the remaining boilers in Building 115 and 515 willmore » be abandoned in-place. Total expenditures required to complete this modernization program are $59 million in FY 1982 dollars or $69 million in actual dollars. Funding allocations are anticipated for FY 1985 through FY 1989.« less

  • The New Brighton/Arden Hills site, also known as the Twin Cities Army Ammunition Plant (TCAAP) site, is in New Brighton, Minnesota. Past disposal of ammunition manufacturing wastes onsite resulted in contamination of ground water beneath and downgradient of the site. A total of 14 waste-disposal locations have been identified and assigned as Sites A through K. During remedial investigations at Site D, soil was discovered to be contaminated with PCBs and other organic and metal contaminants. A soil-gas extraction system was implemented to remove the source of volatile organic contamination and reduce the potential of migration to ground water. Inmore » implementing the soil gas extraction system, PCB-contaminated soil was removed, stockpiled near Site D, and sealed with a plastic-liner material. The interim remedy addresses the treatment and disposal of contaminated soil that is stockpiled near Site D. The primary contaminants of concern affecting the soil are VOCs including TCE and PCE, other organics including PCBs, and metals including arsenic and lead.« less

  • The decision document presents the selected remedial action for addressing groundwater contamination at operable unit 1 (OU-1) of the New Brighton/Arden Hills Superfund Site in Ramsey County, Minnesota. The NB/AH site has been divided into three operable units. The first operable unit, OU-1, addressed by the remedy selected in this ROD, consists of the North Plume of off-TCAAP contaminated groundwater.
