Abstract:  The National Aeronautics and Space Administration NASA Langley Research Center (LaRC) is a 787-acre NASA research center located in southeastern Virginia in the Hampton Roads area. It is bounded by State Route 172, Brick Kiln Creek, and Langley Air Force Base (AFB). NASA LaRC together with Langley AFB was finalized on the National Priorities List (NPL) in 1994. Groundwater in the area can be found at a depth of 5 to 50 feet below the land surface. This aquifer, known as the Columbia Aquifer, is brackish and is limited to lawn and garden watering. Both the Yorktown and the Yorktown-Eastover Aquifers underlie the Columbia Aquifer. The Yorktown-Eastover Aquifer is confined and is used as a source of domestic potable water.

The primary function of NASA LaRC is research and development of advanced technologies for aircraft and spacecraft. In conducting its research and development mission, NASA LaRC requires many support facilities including underground storage tanks (USTs) for fuel and other raw products, power plants, wind tunnels, laboratories and administrative buildings. All of these facilities have the potential to impact the environment through disposal activities, transfer operations and inadvertent releases such as spills or mechanical malfunctions.
Remedy:  Langley Air Force Base (AFB), the Environmental Protection Agency (EPA), and Virginia Department of Environmental Quality (VDEQ) have determined that no action is necessary for this site. Risk assessment results indicate that OU42 soils do not pose an imminent or substantial danger to public, health, welfare, or the environment.
