Letterkenny Army Depot (LEAD) is located in Southcentral Pennsylvania in Franklin County, five miles north of the Borough of Chambersburg. The depot covers 19,243 acres, most of which is devoted to ammunition storage (16,895 acres). Warehousing, vehicle storage, industrial/maintenance, administrative and recreational activities, and housing also occurred at the site. These operations consisted of cleaning, stripping, painting, lubrication, and plating activities, which involved the use of solvents, blast media, paints, chemicals, petroleum products, and metals. Storage spills, releases, and disposal of these materials led to the current environmental concerns at LEAD.

Surface drainage at LEAD is divided into two watersheds - the Susquehanna River to the northeast and the Potomac River to the southwest. Both eventually drain into the Chesapeake Bay. The property of LEAD consists primarily of industrial and developed land, small stands of trees and open grassy areas, and agricultural areas. There is not a viable source of groundwater available within LEAD boundaries to supply the Depot's industrial mission. The only use of groundwater in the area is outside LEAD, where some individual homes depend on the groundwater for their domestic supply and as a water supply for livestock.

LEAD was established in January 1942, as an ammunition storage facility. The facility is divided into two different parts: the property disposal office (PDO) and the Southeastern (SE) area. The PDO area encompasses approximately 1,490 acres in the southern part of the Depot. The SE Area encompasses approximately 1,136 acres and has eight Operable Units (OUs) associated with it.

In February 1995, the US Secretary of Defense submitted a recommendation to Congress that LEAD be selected for realignment. Between 1980 and 1988, numerous environmental investigation programs were conducted at LEAD to evaluate potential contamination in the soil and groundwater at the Depot. InFebruary 1989, a Federal Facilities Agreement (FFA)was reached between the US Department of Defense (DoD), the Environmental Protection Agency (EPA), and the Pennsylvania Department of Environmental Protection (PADEP).

Operable Unit 6 (OU6):
OU6 is composed of Base Realignment and Closure (BRAC) Waste Sites, located in the to-be-excessed part of the PDO Area. Based on the information collected to date for the PDO Area, OU6 is one of six OUs that have been created. A Record of Decision (ROD) was completed for OU6 in September 1998.
 
Remedy:  The selected remedy shall include the following components: restricting the property for commercial and industrial use only; not permitting soil excavation activities below a depth of three feet above the water table without prior approval of the Army; not permitting construction of any subsurface structure for human occupation without the prior approval of the Army, Pennsylvania Department of Environmental Protection (PADEP), or the Environmental Protection Agency (EPA); restricting access or use of the groundwater underlying the property without prior written approval of the Army, PADEP, and the EPA. In addition, upon transfer of the property, the Army, in consultation with EPA and PADEP, will establish periodic inspection procedures to ensure adherence to the institutional controls.
