Public Notice

New iconOct. 25, 2019 - Department of Natural Resources hosts public meeting on Litton Systems and Electro-Pac sites - The Missouri Department of Natural Resources invites 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. The meeting will be held from 4 to 8 p.m. on Thurs., Nov. 7, at the Relics Event Center, 2015 W. Battlefield Road, Springfield.

Site Description

The former Litton Systems Inc. site is located at 4811 West Kearney Street 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.

Water Testing and Treatment Systems

What if I'm not in the area of interest, but want to have my well tested myself?

Local Laboratory: PDC Laboratories
PDC Lab in Springfield will take a walk in request and provide residents with containers to collect samples along with an instruction sheet and a chain-of-custody. The resident would have to pay up-front ($180) for the EPA Method 524 VOC Drinking Water analysis. Turnaround time is 8 business days and the samples are sent to the certified PDC Lab listed on the link above that is located in Peoria, IL.

What if I have TCE in my water below the MCL and I want to install a treatment system myself?
MoDNR cannot recommend a water system or a company that sells water treatment systems; however, when we searched, we found these local companies that do sell and install whole house carbon filtration water treatment systems:

ECOWATER Systems, 557 South Ingram Mill Road, Springfield 417-832-8479

Culligan of Springfield, 2111 East Central Court, Springfield 417-863-9500

The National Sanitation Foundation (NSF) tests and certifies water treatment systems for reducing specific contaminants in drinking water:
