Annual Report of Monitoring at Barnes, Kansas, in 2013
- Argonne National Lab. (ANL), Argonne, IL (United States)
Barnes, Kansas, is a small rural community (population approximately 150) in Washington County, in north-central Kansas. Barnes is located in Section 9, Township 4 South, Range 5 East, at approximate latitude 39°43'0" north and longitude 96°52'25" west. The city lies in a transition zone between the Flint Hills and the glaciated region. The area’s topography consists of gently sloping hills of Pleistocene loess (< 20 ft) overlying a shale unit and interbedded shale, limestone, and siltstone of the Permian Chase Group. Groundwater for the public water supply is obtained from wells PWS2 and PWS3 at reported depths of 155 ft and 160 ft below ground level (BGL), respectively, located in the northwestern portion of the city. The water is produced from the bedrock aquifer of the Chase Group. In 1986, low levels of carbon tetrachloride were detected in public supply wells PWS2 (2.1 μg/L) and PWS3 (0.5 μg/L), below the maximum contaminant level of 5.0 μg/L for carbon tetrachloride in drinking water. Multiple samplings of the wells in 1986-1996 found repeated sporadic detections of carbon tetrachloride at low concentrations. In 1996-1999, the Kansas Department of Health and Environment (KDHE) conducted two investigations to identify potential sources for the carbon tetrachloride in groundwater and to determine the extent of the contamination. In 2006, the CCC/USDA assumed responsibility for the site investigation relating to potential carbon tetrachloride contamination. Initially, the CCC/USDA developed and implemented a work plan for targeted groundwater sampling and monitoring well installation. The investigation and subsequent monitoring were performed by the Environmental Science Division of Argonne National Laboratory. This report contains results of the 2013 testing.
