In early 2005, Argonne National Laboratory conducted an Engineering Evaluation/Cost Analysis (EE/CA; Argonne 2005b) to address carbon tetrachloride contamination identified in groundwater and surface water at Murdock, Nebraska, approximately 22 mi east-northeast of Lincoln (Figure 1.1). The EE/CA study was performed for the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA), as the technical basis for a proposed removal action for the Murdock site. The EE/CA was conducted in compliance with an Administrative Order on Consent issued for Murdock by the U.S. Environmental Protection Agency (EPA 1991). Three removal action alternatives were examined through the use of site-specific data and predictive simulations of groundwater flow and contaminant transport performed with calibrated numerical models. The alternatives were evaluated individually and compared against performance criteria established under the National Oil and Hazardous Substances Pollution Contingency Plan and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). On the basis of these evaluations, an alternative employing phytoremediation in conjunction with seasonal groundwater extraction and treatment by spray irrigation was recommended by the CCC/USDA to permanently reduce the carbon tetrachloride contaminant levels in groundwater and surface water at the site. The proposed alternative is being implemented in cooperation with the EPA. Under …

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

A report about the Geology of three locations in Nebraska. Each location primarily are made up of Shale and chalk of Late Cretaceous age.

The following report was prepared as part of a program of the Department of the Interior for the development of the Missouri River basin. The report focuses on the study of the geology of part of south-central Nebraska, with emphasis on the deposits of the Pleistocene age and their engineering characteristics.

"Results of a reconnaissance geochemical survey of the Broken Bow Quadrangle, Nebraska are reported. Statistical data and aerial distributions for uranium-related variables are presented for 578 groundwater and 442 stream sediment samples. Also included is a brief discussion on location and geology." (from Abstract)

The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) operated a grain storage facility in Waverly, Nebraska, from 1952 to 1974. During this time, the grain fumigant '80/20' (carbon tetrachloride/carbon disulfide) was used to preserve stored grain. In 1982, sampling by the U.S. Environmental Protection Agency (EPA) found carbon tetrachloride contamination in the town's groundwater. After an investigation of the contaminant distribution, the site was placed on the National Priority List (NPL) in 1986, and the CCC/USDA accepted responsibility for the contamination. An Interagency Compliance Agreement between the EPA and the CCC/USDA was finalized in May 1988 (EPA 1990). The EPA (Woodward-Clyde Consultants, contractor) started immediate cleanup efforts in 1987 with the installation of an air stripper, a soil vapor extraction system, a groundwater extraction well, and groundwater and soil gas monitoring wells (Woodward-Clyde 1986, 1988a,b). After the EPA issued its Record of Decision (ROD; EPA 1990), the CCC/USDA (Argonne National Laboratory, contractor) took over operation of the treatment systems. The CCC/USDA conducted a site investigation (Argonne 1991, 1992a,b), during which a carbon tetrachloride plume in groundwater was discovered northeast of the former facility. This plume was not being captured by the existing groundwater extraction system. The remediation …

Interview with Jennifer Leia Krier, a USAF Afghan War veteran and Bronze Star recipient from Fremont, Nebraska. Krier discusses her time at the University of Nebraska, ROTC, becoming a logistics planning officer, work at Yokota Air Base in Japan, the effect of 9/11 and the War on Terror on military life, struggles as a servicewoman and misogyny, joint training with the Army, deployment to Kuwait, deployment to Afghanistan, work and leadership at the brigade level, female integration in combat units, leaving active duty for the reserves, and life off-duty. In appendix is an overview of Krier's Air Force career, photos of her, and photos of her commendations.
