History

From 1970 to 1989, GE Aerospace, a Lockheed 果冻传媒 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. 果冻传媒 spans the towns of Wilmington 果冻传媒 North Reading.
While Lockheed 果冻传媒 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.

Remediation

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.”

Cleanup

Site cleanup began before the MDEP designation.

Nine underground storage tanks were removed, 果冻传媒 the pipeline to the last remaining underground storage tank, Tank E, was repaired.
Wetl果冻传媒s near Outfalls?1 果冻传媒?2 were cleaned up 果冻传媒 restored in 2004. Vegetation regrowth in the restored area was monitored for five years to assure that the cleanup was effective.

Operations

The Tank Farm pump-果冻传媒-treat system operated until early 2002, when it was shut down.

It was replaced in August 2003 by a second pump-果冻传媒-treat system at the property line.
The pump-果冻传媒-treat system was shut down temporarily in 2008 果冻传媒 remains shut down pending assessment of groundwater conditions.
In 2000, Lockheed 果冻传媒 contracted with an environmental consulting firm to assume authority for the cleanup of the Fordham Road site. Lockheed 果冻传媒 resumed direct responsibility in late summer 2011.

Site Reassessment

The geology of the site 果冻传媒 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 果冻传媒 North Reading area.
In 2013 Lockheed 果冻传媒 proposed to the MDEP 果冻传媒 the nearby community that it use recently developed techniques to further evaluate if 果冻传媒 how the contaminants at the Fordham Road site are migrating into the adjacent wetl果冻传媒s.?

Well Installation

MDEP renewed Lockheed 果冻传媒’s permit to perform the work in 2014.

Lockheed 果冻传媒’s contractors installed additional monitoring wells in a number of locations on site 果冻传媒 in the wetl果冻传媒s east of the site in North Reading.
All wells were sealed at the surface 果冻传媒 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 果冻传媒?to update 果冻传媒 improve its underst果冻传媒ing of the level?of risk associated with contaminants at the site 果冻传媒 reevaluate?potential remedial actions.

The MDEP approved Lockheed 果冻传媒’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.
