NewJan. 10, 2020 - Missouri Department of Health and Senior Services Springfield Community Questionnaire Resident Letter and Enclosures The Missouri Department of Health and Senior Services has been working with the Missouri Department of Natural Resources to ensure public health protection related to trichloroethylene (TCE) in private well water associated with a groundwater contaminant plume originating from the Former Litton Systems, Inc. site in Springfield. During the recent open house and informational meeting hosted by the department, DHSS announced they were developing a public health consultation to help evaluate potential community exposures to TCE in private well water and that they would seek community input through a questionnaire intended to help gather community concerns and information on how best to communicate with the community. The following is a link to the online community questionnaire. The deadline for submission of the questionnaire is Jan. 31, 2020. If mailing in your survey, please mail to:

Site Description

The former Litton Systems Inc. site is located at 4811 W. Kearney St. in Springfield on approximately 70 acres of land just east of the Springfield-Branson National Airport. Litton Systems Inc. began manufacturing printed circuit boards in the 1960s and closed in 2007. The facility was demolished in 2008, and the site is now a vacant lot with only the concrete building slab remaining. The site is owned by Northrop Grumman Corporation Guidance and Electronics Company Inc., a subsidiary of Northrop Grumman Corporation that acquired the site from Litton Systems Inc. in 2001.

The Missouri Department of Natural Resources entered into a legal order, known as a consent decree, with Northrop Grumman in March 2010 to perform investigation and cleanup of the Litton site.The department is overseeing this cleanup through its Superfund Cooperative Program, an alternative for contaminated sites that otherwise would be referred to the U.S. Environmental Protection Agency.

Description of Contamination

During the course of operation, the facility generated wastes containing metals, predominantly copper, and volatile organic compounds (VOCs), predominantly trichloroethene (TCE). Until the early 1980s, the facility managed wastes in a series of on-site waste management units consisting of shallow lagoons, and waste piles and pits. The historic waste management units did not fully contain the materials; investigations of surrounding soils, shallow groundwater, deep groundwater and vapor intrusion have been conducted to determine the extent of potential on-site and off-site contamination.

The area in and around Springfield has an extensive network of voids, caverns and sinkholes in the shallow bedrock, and springs that surface at various points. This “karst” geology provides selective pathways for contamination to potentially travel farther than in soil or saturated groundwater zones. In karst geology, groundwater contaminant plumes are difficult to delineate because they often do not follow a predictable pattern. The department conducted a number of dye trace studies that showed materials traveled distances from 0.4 to 6.3 miles; additional investigations are ongoing.

Community Involvement

Nov. 7, 2019 - The Missouri Department of Natural Resources invited the public to an open house and informational meeting about the former Litton Systems Inc. site in Springfield and the former Electro-Pac site in Willard.
