Title: Final report : 2004 monitoring well installation and sampling at Centralia,Kansas.

Abstract

This document reports on monitoring well installation and sampling in 2004 at the location of a grain storage facility formerly operated in Centralia, Kansas, by the Commodity Credit Corporation (CCC) of the U.S. Department of Agriculture (USDA). Argonne National Laboratory is conducting environmental investigations of carbon tetrachloride contamination in groundwater at this site for the CCC/USDA. With the approval of the Kansas Department of Health and Environment (KDHE), Argonne installed six monitoring wells at the former facility in July 2004 to supplement existing monitoring points (piezometers) installed during Argonne's Phase I investigation in 2002. Together, the monitoring wells and piezometers constitute a monitoring network designed to (1) confirm the lateral distribution of carbon tetrachloride in the groundwater, (2) track any migration of contaminants that might take place, and (3) monitor aquifer geochemical characteristics. To verify that the six new monitoring wells had been developed adequately, they were sampled after their installation in July 2004 for analysis for volatile organic compounds (VOCs). The monitoring wells were sampled again in August 2004, after a stabilization period of four weeks. Five of the Phase I piezometers were also sampled in August 2004. Results of analysis of the August 2004 groundwater samples for VOCsmore » confirmed the Phase II investigation's findings (based on sampling in March and April 2003) that carbon tetrachloride contamination in groundwater is generally confined to the boundary of the former CCC/USDA facility. Little migration of contamination from the former facility has been evident. Nevertheless, the network of monitoring wells now in place may not be adequate to delineate the extent of the plume. Future expansion of the network will proceed per agreement between the CCC/USDA and the KDHE. The groundwater samples collected in August 2004 were also analyzed for attenuation parameters that are helpful in determining whether the subsurface environment is suitable for natural in situ biodegradation of carbon tetrachloride. A preliminary screening of the results with a protocol of the U.S. Environmental Protection Agency showed limited evidence for active reductive dechlorination, one of the anaerobic processes by which carbon tetrachloride is biodegraded. These results indicate that additional monitoring of the groundwater contamination at the former CCC/USDA facility at Centralia is merited. On the basis of the findings and conclusions of the Phase I and Phase II investigations, as well as the results of the 2004 well sampling, a program of twice yearly groundwater monitoring in the expanded network is recommended to collect the data necessary to (1) monitor changes in plume dynamics and (2) evaluate the suitability of monitored natural attenuation as a remedial option for the Centralia site. This monitoring program should be conducted for a minimum of two years. After completion of the two-year monitoring program, remedial action objectives and potential corrective action alternatives are to be developed to address the groundwater contamination at Centralia.« less

  • This report documents the activities associated with the installation in 2004 of three groundwater monitoring wells at Morrill, Kansas, and the subsequent sampling of these wells and the six existing Kansas Department of Health and Environment (KDHE) monitoring wells. Also sampled were known private wells located within and downgradient of an area of groundwater contaminated with carbon tetrachloride. These activities were conducted as part of an ongoing environmental investigation at Morrill that is being performed by the Environmental Research Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S.more » Department of Energy (DOE). The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), has entered into an interagency agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. The need for three additional monitoring wells at Morrill to supplement the existing sixwell network initially installed by the KDHE (GeoCore 1996) was documented in a letter report (Argonne 2003a), based on the data collected in October 2003, during the Phase I-Phase II expedited site characterization (Argonne 2004a). In December 2003, following approval of the proposed locations by the KDHE, a work plan for the installation and sampling of the monitoring wells was prepared and submitted to the KDHE (Argonne 2004b). This work plan, together with subsequent modifications (Argonne 2004c), was approved by the KDHE on April 8, 2004. Field work associated with the installation of the three monitoring wells was conducted in May 2004. Sampling of the existing monitoring wells and the known private wells within and downgradient of an area of groundwater contaminated with carbon tetrachloride occurred in June 2004. For one private well, permission to sample was denied. One private well at the co-op was sampled in February 2004, and one private well identified after June 2004 was sampled in August 2004.« less
  • This ''Work Plan'' outlines the scope of work for a targeted groundwater sampling investigation and monitoring well installation at Barnes, Kansas. This activity is being conducted at the request of the Kansas Department of Health and Environment (KDHE), in accordance with the intergovernmental agreement between the KDHE and the Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA). Data resulting from the proposed work will be used to determine the hydraulic gradient near the former CCC/USDA facility, delineate the downgradient carbon tetrachloride plume, and determine additional monitoring requirements at Barnes. The overall goal is to establishmore » criteria for monitoring leading to potential site reclassification. The proposed work will be performed on behalf of the CCC/USDA by the Environmental Science Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The Farm Service Agency of the USDA has entered into an interagency agreement with DOE, under which Argonne provides technical assistance with environmental site characterization and remediation at former CCC/USDA grain storage facilities. Argonne issued a ''Master Work Plan'' (Argonne 2002) to provide general guidance for all investigations at former CCC/USDA facilities in Kansas. The ''Master Work Plan'', approved by the KDHE, contains the materials common to investigations at all locations in Kansas.

  • This document reports the results of groundwater sampling in September-October 2005 and March 2006 at the grain storage facility formerly operated at Centralia, Kansas, by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA). These activities were the first and second twice yearly sampling events of the two-year monitoring program approved by the CCC/USDA and Kansas Department of Health and Environment (KDHE) project managers. The initial monitoring network sampled in September and October 2005 consisted of six monitoring wells (MW1-MW6) installed in 2004, plus five groundwater piezometers (SB01, SB04, SB05, SB08, SB09) installed in 2002. The combined September-Octobermore » 2005 sampling was the first monitoring event in the planned two-year program for Centralia. The groundwater samples collected in both September and October were analyzed for volatile organic compounds (VOCs), and samples collected in September were analyzed for dissolved hydrogen and additional groundwater parameters to aid in evaluating the potential for reductive dechlorination processes. After the monitoring in September-October 2005, Argonne recommended expansion of the initial monitoring network. Previous sampling (August 2004) had already suggested that this network of six monitoring wells and five piezometers was inadequate to delineate the extent of the carbon tetrachloride plume. With the approval of the CCC/USDA and KDHE project managers, the monitoring network was expanded in January 2006 through the installation of four additional monitoring wells (MW7-MW10) and one new piezometer (SB07R) to replace a damaged piezometer (the former SB07). Details of the monitoring well and piezometer installations are reported in this document. The expanded monitoring network of ten monitoring wells (MW01-MW10) and six piezometers (SB01, SB04, SB05, SB07R, SB08, and SB09) was sampled in March 2006. This March 2006 sampling was the second monitoring event in the planned two-year program. Results of analyses for VOCs showed further increases in contaminant levels and expansion of the carbon tetrachloride plume toward the south and west from the former CCC/USDA facility. The groundwater samples collected in March 2006 were also analyzed for additional groundwater parameters to aid in the evaluation of the potential for reductive dechlorination processes. Preliminary screening of groundwater parameters provided limited evidence that reductive dechlorination of carbon tetrachloride is taking place at some locations on the former CCC/USDA facility. Groundwater levels measured manually in September 2005, March 2006, and June 2006 were used to map the potentiometric surface at Centralia. Overall, these results were consistent with each other and with previous measurements, generally indicating a groundwater flow direction toward the south-southwest from the former CCC/USDA facility. Data recorders installed in wells MW01-MW06 in August 2004 are gathering long-term data on the groundwater elevation and gradient. Data downloaded in March 2005, September 2005, and June 2006 indicate that two wells north and west of the former CCC/USDA facility boundary show distinct, transient and seasonal water level variations. In contrast, two different wells southwest and south of the former facility boundary show virtually no response to the same events. The first two monitoring events of the planned two-year monitoring program for Centralia have demonstrated increased carbon tetrachloride concentrations and lateral expansion of the contaminated zone. Argonne recommends that the CCC/USDA and KDHE project managers consider development and approval of a work plan to expedite the selection and implementation of an active remedial alternative addressing the concentrated areas of groundwater contamination before the end of the two-year monitoring program in 2007.« less
  • This Work Plan outlines the scope of work for a program of twice yearly groundwater monitoring at the site of a former grain storage facility at Centralia, Kansas (Figure 1.1). The purposes of this monitoring program are to follow changes in plume dynamics and to collect data necessary to evaluate the suitability of monitored natural attenuation as a remedial option, under the requirements of Kansas Department of Health and Environment (KDHE) Policy No.BER-RS-042. This monitoring program is planned for a minimum of 2 yr. The planned monitoring activity is part of an investigation at Centralia being performed on behalf ofmore » the Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), by the Environmental Research Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE).

  • In September 2005, periodic sampling of groundwater was initiated by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in the vicinity of a grain storage facility formerly operated by the CCC/USDA at Centralia, Kansas. The sampling at Centralia is being performed on behalf of the CCC/USDA by Argonne National Laboratory, in accord with a monitoring program approved by the Kansas Department of Health and Environment (KDHE). The objective is to monitor levels of carbon tetrachloride contamination identified in the groundwater at Centralia (Argonne 2003, 2004, 2005a). Under the KDHE-approved Monitoring Plan (Argonne 2005b), the groundwater is beingmore » sampled twice yearly (for a recommended period of two years) for analyses for volatile organic compounds (VOCs), as well as measurement of selected geochemical parameters to aid in the evaluation of possible natural contaminant degradation (reductive dechlorination) processes in the subsurface environment. The sampling is presently conducted in a network of 11 monitoring wells and 5 piezometers (Figure 1.1), at locations approved by the KDHE (Argonne 2006a). The results of groundwater sampling and VOCs analyses in September-October 2005, March 2006, and September 2006 were documented previously (Argonne 2006a,b). The results have demonstrated the presence of carbon tetrachloride contamination, at levels exceeding the KDHE Tier 2 Risk-Based Screening Level of 5 {micro}g/L for this compound, in a broad groundwater plume that has shown little movement. This report presents the results of the groundwater sampling at Centralia in March 2007, performed in accord with the KDHE-approved Monitoring Plan (Argonne 2005b). The March 2007 sampling represents the fourth monitoring event performed under the recommended two-year monitoring program approved by the KDHE. A final sampling event under this program is scheduled for September 2007.« less
