From 1970 to 1989, GE Aerospace, a Lockheed Martin heritage company, operated its Aerospace Instruments Control Systems Department.
- The site is in a 13‑acre industrial park at 50 Fordham Road in Wilmington, Mass. and spans the towns of Wilmington and North Reading.
- While Lockheed Martin no longer owns the property, it retains responsibility for environmental cleanup associated with the former GE Aerospace business.
- In November 1999, private citizens petitioned the Massachusetts Department of Environmental Protection to have the four sites so named in accordance with Massachusetts Law.
Contamination at the site first came to the attention of the Massachusetts Department of Environmental Protection (MDEP) in early 1986.
- The Department was investigating sources of contaminants in the Stickney Well, a public water well located 500-feet east of the site. Over time, four areas of concern were identified at the Fordham Road site.
- Consequently, in October 1987 the MDEP classified the property as a “priority disposal site.”
Site cleanup began before the MDEP designation.
- Nine underground storage tanks were removed, and the pipeline to the last remaining underground storage tank, Tank E, was repaired.
- Wetlands near Outfalls 1 and 2 were cleaned up and restored in 2004. Vegetation regrowth in the restored area was monitored for five years to assure that the cleanup was effective.

The Tank Farm pump-and-treat system operated until early 2002, when it was shut down.
- It was replaced in August 2003 by a second pump-and-treat system at the property line.
- The pump-and-treat system was shut down temporarily in 2008 and remains shut down pending assessment of groundwater conditions.
- In 2000, Lockheed Martin contracted with an environmental consulting firm to assume authority for the cleanup of the Fordham Road site. Lockheed Martin resumed direct responsibility in late summer 2011.
The geology of the site and surrounding region is complex, reflecting ancient glacial activity.
- The Fordham Road site is one of four designated as Public Involvement Plan (PIP) sites, in the Wilmington, Reading and North Reading area.
- In 2013 Lockheed Martin proposed to the MDEP and the nearby community that it use recently developed techniques to further evaluate if and how the contaminants at the Fordham Road site are migrating into the adjacent wetlands.
MDEP renewed Lockheed Martin’s permit to perform the work in 2014.
- Lockheed Martin’s contractors installed additional monitoring wells in a number of locations on site and in the wetlands east of the site in North Reading.
- All wells were sealed at the surface and their locations
documented by survey. Groundwater from the newly installed wells has been sampled for the primary contaminants of concern.
- Restoration will be completed in the spring of 2015.
Supplemental Site Assessment
The additional data being collected from the supplemental site assessment will make it possible for Lockheed Martin to update and improve its understanding of the level of risk associated with contaminants at the site and reevaluate potential remedial actions.
- The MDEP approved Lockheed Martin’s request for more time to complete its characterization of the extent of contamination at the site; the extension was granted to May 3, 2017.
