Cleanup Status
After a more comprehensive round of groundwater monitoring in May 2014, high concentrations of trichloroethene were discovered at Monitoring Well MW06A. Because of this well’s location close to and just upgradient of the building, a vapor intrusion investigation was begun in November 2014 that included the collection of sub-slab and indoor air samples from several areas within the building. To date, no indoor air samples have exceeded protective screening levels, but several sub-slab samples have exceed screening levels. In April 2015, a sub-slab depressurization system was installed in the building to mitigate the sub-slab contamination. The vapor intrusion investigation will continue at least through 2016. In addition, a soil investigation in the area of MW06A is proposed to take place later in 2016 to determine if a localized source of contamination exists in this area and can be remediated, and groundwater monitoring continues to ensure that contamination is not migrating off-site, general trends of contaminant concentrations site-wide are stable or continue to decrease, and favorable conditions for monitored natural attenuation continue to exist.
Site Description
The 67-acre site was owned and operated by Honeywell Inc. from 1965 until 1986. During this time, Honeywell manufactured instruments and control systems for industry. In 1986, the facility was sold to 1100 Virginia Drive Associates. Honeywell continued to lease a portion of the facility for manufacturing of electronic controls and mechanical valve assemblies until March, 1993, when all of Honeywell’s manufacturing operations were transferred to other locations. Honeywell continued to lease a portion of the facility for office space until 2006. The facility was subsequently sold to Liberty Property Trust in 2006 and is currently being leased to other parties.
Contaminants at this Facility
Groundwater beneath the facility is contaminated with trichloroethene (TCE) along with lower levels of other chlorinated ethenes. Groundwater is not used for any purposes at the facility; therefore, the primary potential exposure route to this contamination is through vapor intrusion into indoor air. Several areas of the facility continue to be monitored to ensure that indoor air is not being adversely impacted by vapors from contaminated groundwater.

No formal institutional controls have been applied to the Facility at this time; however, it is likely that institutional controls prohibiting the use of groundwater beneath the Facility and restricting land use at the Facility to non-residential purposes will be implemented in the future. A groundwater pump and treatment system , initially required in an 1995 EPA order, has been approved by the EPA to be shutdown in October 2012.
Land Reuse Information at this Facility
The facility continues to be leased to several commercial and industrial tenants.
Site Responsibility at this Facility
Resource Conservation and Recovery Act (RCRA) Corrective Action activities at this facility have been conducted under the direction of EPA Region 3.
