Wright-Patterson Air Force Base (WPAFB) is located in southwestern Ohio, east of Dayton and adjacent to Fairborn. The base is approximately 60 miles north of Cincinnati and 50 miles west of Columbus. It lies in Montgomery and Greene Counties.

The installation is composed of Wright and Patterson Fields, which are separated by State Route 444. Wright Field comprises area B, approximately 2,800 acres; and Patterson Field comprises Areas A and C, approximately 5,711 acres. The base has a significant proportion of its acreage devoted to logistical support/warehouse land uses, research and development and land uses, and administrative and classroom space. Airfield functions constitute 24 percent of all on-base land uses. The base has more than 2,500 acres of undeveloped land, but much of that acreage is restricted from certain types of development by environmental constraints, such as flood plains, steep slopes, Indian burial mounds, and other cultural/natural features. Other constraints, such as a new national park, laser testing facilities, explosive safety zones and clear zones for runways also restrict development in certain areas.

Adjacent land uses include agricultural, residential, institutional, commercial, and industrial. Commercial strip development in Fairborn and Riverside are situated across from the installation on State Route 444 and Springfield Pike and adjacent to the Page Manor residential area to the southwest. Industrial activities are situated to the northeast and northwest. Wright State University is adjacent to the south central portion of the installation. Open space remains primarily along the north/northwestern boundary. Residential development is established all along the south/southeastern boundary and occurs sporadically along other perimeter areas.

In 1981, the installation restoration program (IRP) was initiated at WPAFB. As part of the IRP, a Remedial Investigation/Feasibility Study (RI/FS) Work Plan was developed for 39 potential waste disposal sites. Twenty-five other sites were also identified and underwent investigations. All of these remaining sites, along with the original 39, were grouped into 11 operable units (OUs) across the base.
Remedy:  No action is the selected remedy for 21 sites within five operable units at WPAFB. The no action decision for these sites deals only with soils at the sites. Remedies for groundwater, surface water, and sediments at the no action sites will addressed under the Basewide Monitoring Program.

The selected remedy of no action includes currently existing conditions such as institutional controls and access/deed restrictions. All of these sites are located within an active military installation with limited access. Additionally, some sites have fencing around them, further limiting access. Digging/excavation at any of these sites is currently restricted by the nature of the installation and should remain minimal. If, in the future, portions of the base are sold for residential development, etc., the appropriate land use would need to be evaluated for those specific applications. No action is protective of public health because there is no current exposure to the subsurface contamination, however low, and future exposure is considered extremely unlikely because of the nature of the land uses.
