Background & Timeline
Lockheed Martin has been committed to the community of Tallevast, Florida, since assuming ownership of the former Loral American Beryllium Company site in 1996. With the discovery of groundwater contamination in 2000, Lockheed Martin immediately notified the Florida Department of Environmental Protection (FDEP) and began voluntary site cleanup.
Community groups, state and local government agencies and corporate representatives have led a full-scale effort for several years to address the Tallevast contamination issue.
During a due diligence assessment conducted in 2000 to support the land sale of the Loral American Beryllium Company site, volatile organic compounds (VOCs) were identified in shallow groundwater beneath former concrete sumps located on-site at the eastern portion of the facility. The assessment indicated that some contaminants of concern were:
- Trichloroethene (trichloroethylene, TCE) — it has been detected at a range from non-detect to a maximum of 35,000 parts per billion (ppb). The TCE applicable standard in Florida is 3 ppb.
- 1,4-dioxane — it has been detected at a range from non-detect to a maximum of 2,710 ppb. The 1,4-dioxane applicable standard in Florida is 3.2 ppb.
The contaminated groundwater typically occurs at a depth of 20 feet below ground surface or greater.
In August 2005, the Centers for Disease Control & Prevention's Agency for Toxic Substance and Disease Registry published Florida Department of Health's Exposure Investigation health consultation report summarizing indoor air testing of three homes and one community center for 61 volatile organic compounds (VOCs) in the Tallevast area. The findings showed no evidence of harmful vapors existing in residents' homes.

In response to the Tallevast residents' requests for additional information on health risk, Lockheed Martin outlined a plan in June 2005 to assess the current and future risk to human health posed by contaminants in soil and groundwater attributed to the former Loral ABC site. A full-scale effort between Lockheed Martin, the Florida Department of Environmental Protection, Florida Department of Health, Manatee County and community members has assessed the contamination, mapped the groundwater plume, provided water for the community, and prepared for and begun remediation activities to ensure public health and safety.
In addition, the potential public health risk was significantly reduced because Lockheed Martin has worked with Manatee County utility to provide affected homes with a temporary connection to the public water supply. Lockheed Martin and the county utility are working together to get a permanent water connection for those homes.
