The Lockheed Martin facility at 199 Borton Landing Road in Moorestown, N.J., opened in 1954. Originally an asparagus farm, the land was purchased and converted into a manufacturing site by RCA, which is a Lockheed Martin heritage company. For four decades, the site used chlorine-based solvent chemicals in metal parts cleaning operations. It also stored fuel oil in underground storage tanks to feed the boilers. In 1975, the 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 sold from RCA to General Electric, traces of the chlorine-based chemical solvents and fuel oil were found on-site in the soil and groundwater. Immediately after they were discovered, a plan to mitigate the impact of those chemicals to soil and groundwater was developed in coordination with the New Jersey Department of Environmental Protection (NJDEP).

Soil sampling conducted in coordination with the NJDEP over the next two years revealed nine Areas of Concern (AOCs) at the site. A cleanup plan was submitted to the NJDEP and approved in 1992. In 1994, treatment systems were installed to mitigate contaminants in the on-site soil and groundwater. Since then, five of the nine areas have been remediated to levels determined acceptable by the NJDEP. Three AOCs are still in active mitigation in accordance with applicable regulations and oversight by the NJDEP, and one area is in the investigation phase. To mitigate the impacts:

• Three recovery wells were installed near the fuel oil storage tanks to recover the fuel oil that leaked into the groundwater.
• A groundwater treatment system and a vapor extraction system were installed near the former chemical dispensing shed to remove the solvents from both water and the soil.
• A perimeter system was designed and installed along Borton Landing Road to prevent further migration of contaminants in groundwater across the property boundary. The perimeter system currently consists of 10 wells designed to mitigate the presence of solvents in the groundwater.

In December 2008, Lockheed Martin, along with two outside contractors, began conducting investigations related to groundwater and soil contamination at the residences across Borton Landing Road. The investigations targeted a commonly used solvent called trichloroethylene (TCE) and the effects of TCE migrating from the groundwater into soils beneath buildings, known as vapor intrusion. The investigations focused on evaluating the presence and extent of TCE in the groundwater and precautionary testing for vapor intrusion.

In May 2009, Lockheed Martin completed precautionary testing at the properties across Borton Landing Road. Results of the testing found no evidence of vapor intrusion. Lockheed Martin will continue to monitor offsite groundwater monitoring wells and work closely with the NJDEP and Burlington County Department of Heath to adhere to local and state guidance.
