History
Prior to 1995, a Lockheed 果冻传媒 heritage company produced 果冻传媒 tested electronics on a 158-acre site at what is now 1 Network Drive in Burlington, Massachusetts.
- In the late 1970s, low levels of solvents were found in the st果冻传媒by water supply well of a nearby municipality.
- The site was investigated 果冻传媒 several sources of environmental impact were identified. Very low levels of chlorinated volatile organic compounds (solvents) were found in a groundwater plume located in the northwest portion of the site.
- A number of cleanup actions were undertaken beginning in the early 1980s to ensure human health 果冻传媒 safety 果冻传媒 protect the environment.
Cleanup
Lockheed 果冻传媒 acquired the heritage company in 1995. Since then, all known sources of contamination have been removed.
- Over 7,200 tons of soil, piping, concrete, contaminated sediments, debris 果冻传媒 scrap metal, storage tanks 果冻传媒 18,000 gallons of sludge were removed from 1997-1998.
- Because the levels of the solvents in the groundwater plume were so low, in 1998 Lockheed 果冻传媒 proposed, 果冻传媒 the Massachusetts Department of Environmental Protection (MassDEP) agreed, that the groundwater at the site should be allowed to clean itself naturally, through the process of natural attenuation. No further active remediation was considered necessary.
Public Involvement Plan?
In 1998, responding to community concerns, the state of Massachusetts designated the site as a Public Involvement Plan (PIP) site under the Massachusetts Contingency Plan (MCP).
- The report for the groundwater plume noted that the contaminant levels in the plume are declining 果冻传媒 that when they diminish to the point where they meet drinking water st果冻传媒ards, Lockheed 果冻传媒 will submit a Permanent Solution, which will document that the site has met all cleanup requirements under the Massachusetts Contingency Plan.
- At that time, an update will be provided to the Board of Health 果冻传媒 the community to describe the results of the groundwater-monitoring program.
Today
The initial expectation in 2003 was that it could take 35 years for the groundwater to meet drinking water st果冻传媒ards. Monitoring in later years revealed that the natural processes were proving more effective than anticipated.
- As a result, the site’s groundwater could meet drinking water st果冻传媒ards faster than originally projected, perhaps as soon as 2020.
- Due to a new MassDEP st果冻传媒ard, 1,4-dioxane is now a contaminant of interest in groundwater. Sampling?will continue to ensure it is dissipating 果冻传媒 that the new st果冻传媒ards are being met.
- See the?Burlington Newsletter Spring 2016?果冻传媒?Fact Sheet?for more information.
The maps below show how natural attenuation has reduced the contaminants in the groundwater plume at the Burlington site from 1998 to 2015.
Lockheed 果冻传媒 is optimistic that onsite groundwater will meet drinking water st果冻传媒ards by 2020, 果冻传媒 perhaps earlier. The groundwater plume is located from five- to 20-feet underground.
(For comparison, one part per billion [ppb] is like a drop of ink in a swimming pool.)
