Moorestown, NJ

 The facility located at 199 Borton Landing Road in Moorestown, NJ opened in 1954. Originally a vegetable farm, the land was purchased and converted into a manufacturing site by RCA, which later became part of General Electric Company (GE). In 1993, Martin Marietta, a predecessor to Lockheed Martin, purchased the facility from GE.

During its history, the site used chlorine-based solvent chemicals in metal parts cleaning operations. The site also stored fuel oil in underground storage tanks to feed the boilers. In 1975, the existing fuel oil storage tanks were closed, and in 1986 the site installed two new tanks made of double-walled fiberglass with leak sensors.

In 1987, when the site was acquired by GE from RCA, traces of the chlorine-based chemical solvents and fuel oil were found on-site in the soil and groundwater. Immediately upon discovery, a plan to mitigate the impact of those constituents to soil and groundwater was developed in coordination with the New Jersey Department of Environmental Protection (NJDEP).

Sampling conducted under the direction of NJDEP over the next two years identified 15 areas of concern (AOCs) at the site, six of which did not require further action. A clean-up plan was submitted to the NJDEP and approved in 1992. Three additional AOCs were identified subsequent to the 1992 clean-up plan bringing the total number of AOCs to 18. In 1994, treatment systems were installed to mitigate constituents in the on-site soil and groundwater.

Since then, five of the AOCs have been remediated to current levels determined acceptable by the NJDEP. Twelve AOCs are still in active mitigation or reporting in accordance with applicable regulations and one area is in the investigation phase. Below are steps taken to mitigate the impacts, along with the operating status of each remedial component:

  • Three recovery wells were installed near former fuel oil storage tanks to recover fuel oil that leaked into shallow groundwater (active); a recovery system actively removes fuel oil from this area.
  • A groundwater treatment system and a vapor extraction system were installed near a former chemical dispensing shed to remove the solvents from both water and soil (inactive; remediation completed).
  • An in-situ bioremediation pilot test was conducted to treat source material (active).
  • An extensive monitoring well network was installed to monitor groundwater quality beneath, across and beyond the site boundaries (active).
  • A perimeter system was designed and installed along Borton Landing Road to prevent further migration of constituents in groundwater across the property boundary (active).

The principal constituent found in groundwater associated with former site operations is trichloroethene (TCE). It was mainly used as a solvent to remove grease from metal parts. TCE can be found in low concentrations in some household products, including typewriter correction fluid, paint removers, adhesives and spot removers.

Because of recent studies of the potential for vapor intrusion (the potential for volatile organic compounds in groundwater to affect the quality of indoor air) to occur under certain circumstances, Lockheed Martin expanded its remediation efforts in 2007 to include vapor-intrusion testing in cooperation with the NJDEP.

Actions to Minimize Impact to the Public
Lockheed Martin continues to evaluate the environmental conditions at the site to ensure that impacts from groundwater are promptly mitigated. The information below identifies actions in response to site conditions.

  • The potential for exposure to constituents in the drinking water has been eliminated with the connection of residential drinking water sources to the Moorestown municipal water supply system.
  • The perimeter remediation system has been actively removing TCE and other constituents from shallow groundwater since 1995.
  • NJDEP approved and established a groundwater Classification Exception Area (CEA) and Well Restriction Area (WRA) for the onsite and offsite groundwater impacts in March 2002. The CEA and WRA are expected to be in effect through 2030.
  • Lockheed Martin has assessed the potential for vapor intrusion conditions at 52 properties in the area. No further assessment is required at over 95 percent of the properties assessed and none of the sampling results have triggered vapor mitigation systems. Lockheed Martin is conducting additional monitoring at a few properties to confirm previous results in accordance with NJDEP guidance.
