We are currently experiencing technical difficulties with requests for some documents. If an attempt to download an individual document from the “Documents/Photos Available” link does not return the expected results, please contact the Project Manager associated with the Identified Site or the Remedial Section at 785-296-1660. We are working to resolve this problem as quickly as possible and apologize for any inconvenience this may cause.

The Continental Tank Car Corporation Site (CTCC) is located within the boundaries of the North Industrial Corridor Site in Wichita, Kansas. Industrial activities at the two buildings on the site have included storage, ripening of bananas by E.L. Banana House, Inc., and wood finishing and other light manufacturing by Great American Design Fabricators and Impala Industries. Groundwater investigations conducted from 1988 to 1991 at the property and adjacent properties showed a high probability of release of solvents from the facility.

In 1992, CTCC entered in to a Consent Order (CO) agreement with KDHE to conduct a Remedial Investigation (RI). The RI findings identified a soil source area and found soil and groundwater impacts of chlorinated volatile organic compounds (VOCs), including 1,1,1-trichloroethane (1,1,1-TCA), trichloroethene (TCE), cis-1,2-dichloroethene (cis-DCE), and 1,1-dichloroethene (1,1-DCE). In 1997, CTCC signed a second CO with KDHE to monitor the plume, further define the source area, and to develop interim remedial measures for source control.

On-site and off-site investigations have been conducted in a phased approach from 1993 to 2001. A site Remedial Investigation completed in 1994 showed a major source area on the property related to spillage and/or improper disposal of solvents (mainly TCE). A groundwater plume extends off of the property onto City of Wichita property to the south-southwest and subsequently further southwest to the Coleman North site. The plume appears to be controlled/contained by Coleman's groundwater pump and treat system.

CTCC conducted a source-IRM pilot test in December of 2002. The IRM pilot test consisted of injection of Hydrogen Release Compounds (HRC) into vadose soils, the capillary fringe and the upper two feet of the water table to test for in-situ source control and groundwater remediation by enhanced natural reductive dechlorination of VOCs within site soils and groundwater. The results of this test have not been provided to KDHE.

Semi-annual groundwater monitoring is required under the 1997 consent order; however, many of the required sampling events have not been conducted. CTCC has been referred to Legal.
