Technical justification for a request to reclassify the former CCC/USDA facility at Canada, Kansas. (open access)

Technical justification for a request to reclassify the former CCC/USDA facility at Canada, Kansas.

Contamination in groundwater at Canada, Kansas, was discovered in 1997, during limited private well sampling near former grain storage facilities of the Commodity Credit Corporation, U.S. Department of Agriculture (CCC/USDA). Subsequent investigations by the Kansas Department of Health and Environment (KDHE) confirmed carbon tetrachloride and nitrate concentrations in groundwater above the respective maximum contaminant levels (MCLs) of 5.0 {micro}g/L and 10.0 mg/L. The KDHE investigations identified both the former CCC/USDA grain storage facility and a private grain storage facility as likely sources for the carbon tetrachloride contamination. The CCC/USDA funded extension of a rural water district line to provide a permanent alternate water supply, and the KDHE has conducted long-term monitoring under the State Water Plan. This document presents an analysis of the available information for the Canada site, acquired in previous investigations and the long-term KDHE monitoring. This analysis forms the technical justification for a request to reclassify the former CCC/USDA grain storage facility at Canada as a site requiring no further action under the Intergovernmental Agreement (IGA) between the KDHE and the USDA's Farm Service Agency. The KDHE's long-term water level monitoring results indicate a consistent groundwater flow direction to the east-southeast. Consequently, the wells with the highest …

Interim Measure Conceptual Design for Remediation at the Former CCC/USDA Grain Storage Facility at Centralia, Kansas: Pilot Test and Remedy Implementation. (open access)

Interim Measure Conceptual Design for Remediation at the Former CCC/USDA Grain Storage Facility at Centralia, Kansas: Pilot Test and Remedy Implementation.

This document presents an Interim Measure Work Plan/Design for the short-term, field-scale pilot testing and subsequent implementation of a non-emergency Interim Measure (IM) at the site of the former grain storage facility operated by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in Centralia, Kansas. The IM is recommended to mitigate both (1) localized carbon tetrachloride contamination in the vadose zone soils beneath the former facility and (2) present (and potentially future) carbon tetrachloride contamination identified in the shallow groundwater beneath and in the immediate vicinity of the former CCC/USDA facility. Investigations conducted on behalf of the CCC/USDA by Argonne National Laboratory have demonstrated that groundwater at the Centralia site is contaminated with carbon tetrachloride at levels that exceed the Kansas Tier 2 Risk-Based Screening Level (RBSL) and the U.S. Environmental Protection Agency's maximum contaminant level of 5.0 {micro}g/L for this compound. Groundwater sampling and analyses conducted by Argonne under a monitoring program approved by the Kansas Department of Health and Environment (KDHE) indicated that the carbon tetrachloride levels at several locations in the groundwater plume have increased since twice yearly monitoring of the site began in September 2005. The identified groundwater contamination currently poses no unacceptable …

Final Work Plan for Targeted Investigation at Inman, Kansas. (open access)

Final Work Plan for Targeted Investigation at Inman, Kansas.

In 1997, low levels of carbon tetrachloride (below the maximum contaminant level [MCL] of 5 {micro}g/L) were detected in groundwater at Inman, Kansas, by the Kansas Department of Health and Environment (KDHE). The 1997 KDHE sampling was conducted under the U.S. Department of Agriculture (USDA) private well sampling program. The Commodity Credit Corporation (CCC), a USDA agency, operated a grain storage facility in Inman from 1954 to 1965. Carbon tetrachloride is the contaminant of primary concern at sites associated with former CCC/USDA grain storage operations. Inman is located in southwest McPherson County, approximately 10 mi southwest of the city of McPherson (Figure 1.1). To determine whether the former CCC/USDA facility at Inman is a potential contaminant source and its possible relationship to the contamination in groundwater, the CCC/USDA has agreed to conduct an investigation at Inman, in accordance with the Intergovernmental Agreement between the KDHE and the Farm Service Agency of the USDA. For this work plan, Argonne compiled historical data related to the previous investigations and grain storage operations at Inman. Through a review of documents acquired from all available sources, other potential contaminant source areas (in addition to the former CCC/USDA facility) have been identified as (1) the …

March-April 2007 Monitoring Results for Morrill, Kansas. (open access)

March-April 2007 Monitoring Results for Morrill, Kansas.

In September 2005, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) initiated periodic sampling of groundwater in the vicinity of a grain storage facility formerly operated by the CCC/USDA at Morrill, Kansas. The sampling at Morrill 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), to monitor levels of carbon tetrachloride contamination identified in the groundwater at this site (Argonne 2004, 2005a). Under the KDHE-approved Monitoring Plan (Argonne 2005b), the groundwater is being sampled twice yearly for a recommended period of two years. The samples are analyzed for volatile organic compounds (VOCs), as well as for 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 12 monitoring wells and 3 private wells (Argonne 2006a; Figure 1.1), at locations approved by the KDHE.

Final report : results of the 2006 investigation of potential contamination at the former CCC/USDA facility in Ramona, Kansas. (open access)

Final report : results of the 2006 investigation of potential contamination at the former CCC/USDA facility in Ramona, Kansas.

The investigation reported here was conducted by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in 2006. The investigation addressed carbon tetrachloride contamination on the former CCC/USDA grain storage facility at Ramona, Kansas. The results clearly demonstrate that only minimal contamination is associated with the past use of carbon tetrachloride on the former CCC/USDA property. No soil contamination was detected at concentrations above Kansas Department of Health and Environment (KDHE) risk-based screening level (RBSL) Tier 2 standard of 200 {micro}g/kg for the soil-to-groundwater protection pathway. Carbon tetrachloride concentrations in groundwater above the RBSL and maximum contaminant level (MCL) value of 5.0 {micro}g/L were detected in only two samples, collected at adjacent locations on the southeast part of the property. The relatively low concentrations detected and the limited areal extent of the contamination demonstrate that no imminent threat exists on the former CCC/USDA property to warrant remediation. The soil and groundwater contamination detected on the former CCC/USDA property is clearly separate from contamination detected at off-site locations. The carbon tetrachloride and chloroform contamination in groundwater (at concentrations above the RBSL and MCL value) associated with past activities on the former CCC/USDA property is contained within the property boundaries. …

Final work plan for targeted investigation at Hilton, Kansas. (open access)

Final work plan for targeted investigation at Hilton, Kansas.

This Work Plan outlines the scope of a targeted investigation to update the status of carbon tetrachloride contamination in groundwater associated with grain storage operations at Hilton, Kansas. The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility in Hilton during the 1950s and 1960s. At the time of the CCC/USDA operation in Hilton, grain storage facilities (CCC/USDA and private) were located along the both sides of the former Union Pacific railroad tracks (Figure 1.1). The main grain storage structures were on or near the railroad right-of-way. The proposed targeted investigation, to be conducted by Argonne National Laboratory on the behalf of CCC/USDA, will supplement Argonne's Phase I and Phase II investigations in 1996-1997. The earlier investigations erroneously focused on an area east of the railroad property where the CCC/USDA did not operate, specifically on a private grain storage facility. In addition, the investigation was limited in scope, because access to railroad property was denied (Argonne 1997a,b). The hydrogeologic system at Hilton is potentially complex.

Final Report : Groundwater Monitoring at Morrill, Kansas, in September 2005 and March 2006, With Expansion of the Monitoring Network in January 2006. (open access)

Final Report : Groundwater Monitoring at Morrill, Kansas, in September 2005 and March 2006, With Expansion of the Monitoring Network in January 2006.

This document reports the results of groundwater monitoring in September 2005 and March 2006 at the grain storage facility formerly operated at Morrill, 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 monitoring network sampled in September 2005 consisted of 9 monitoring wells (MW1S-MW5S and MW1D [installed in the mid 1990s] and MW6S-MW8S [installed in 2004]), plus 3 private wells (Isch, Rillinger, and Stone). The groundwater samples collected in this first event were analyzed for volatile organic compounds (VOCs), dissolved hydrogen, and additional groundwater parameters to aid in evaluating the potential for reductive dechlorination processes. After the monitoring in September 2005, Argonne recommended expansion of the initial monitoring network. Previous sampling (August 2004) had already suggested that the initial network 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 3 additional monitoring wells (MW9S-MW11S). Details of the monitoring well installations are …

March 2007 Monitoring Results for Centralia, Kansas. (open access)

March 2007 Monitoring Results for Centralia, Kansas.

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 being 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 …

Recommendations for new monitoring wells at Everest, Kansas. (open access)

Recommendations for new monitoring wells at Everest, Kansas.

On February 15, 2007, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) submitted Recommendations for Remedial Action at Everest, Kansas. Those Recommendations were accepted by the Kansas Department of Health and Environment (KDHE) in a letter to the CCC/USDA dated March 5, 2007. The approved Recommendations document outlines a plan for systematic groundwater sampling and monitoring at Everest to provide data necessary for the critical evaluation of remedial options - including a phytoremediation alternative - for restoration of the groundwater and protection of the surface waters of the intermittent creek at this site. Phase I of the KDHE-approved monitoring plan includes the following activities: (1) Groundwater sampling at existing monitoring wells, with analyses for volatile organic compounds (VOCs) and selected biodegradation parameters; (2) Sampling of surface waters along the intermittent creek for VOCs analyses; and (3) Periodic manual measurement and automated recording of groundwater and surface water levels in the vicinity of the intermittent creek. The locations selected for groundwater and surface water sampling and analyses under the approved monitoring program were determined in consultation with the KDHE. As a result of subsequent discussions among representatives of the KDHE, the CCC/USDA, and Argonne regarding the technical program …

Recommendations for Remedial Action at Everest, Kansas.

On September 7, 2005, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) presented a Scoping Memo (Argonne 2005) for preliminary consideration by the Kansas Department of Health and Environment (KDHE). This document suggested possible remedial options for the carbon tetrachloride contamination in groundwater at Everest, Kansas. The suggested approaches were discussed by representatives of the KDHE, the CCC/USDA, and Argonne at the KDHE office in Topeka on September 8-9, 2005, along with other technical and logistic issues related to the Everest site. In response to these discussions, the KDHE recommended (KDHE 2005) evaluation of several remedial processes, either alone or in combination, as part of a Corrective Action Study (CAS) for Everest. The primary remedial processes suggested by the KDHE included the following: (1) Hydraulic control by groundwater extraction with aboveground treatment; (2) Air sparging-soil vapor extraction (SVE) in large-diameter boreholes; and (3) Phytoremediation. As a further outcome of the 2005 meeting and as a precursor to the proposed CAS, the CCC/USDA completed the following supplemental investigations at Everest to address several specific technical concerns discussed with the KDHE: (1) Construction of interpretive cross sections at strategic locations selected by the KDHE along the main plume migration …
