Stead Solvent Site
The Site is located in the northwest portion of the former Stead AFB in Washoe County, Nevada. The Stead AFB was constructed in the early 1940s. Prior to its construction, the area was primarily utilized for ranching. The site was operated as a military aviation facility until 1958. After 1958, the area was used as a military training facility, light aircraft airport, and for light industrial and manufacturing activities. Acreage from the original Stead AFB was gradually sold or deeded to various parties between 1958 and the present. The general location of the Stead Solvent Site is shown on Figure 1: Site Location Map.
Solvent use on the site could extend back to 1944 when the Stead AFB was constructed and used as a military facility. Bulk solvents were reportedly stored at the former military fuel depot structure located southwest of the intersection of Mt. Anderson Street and Alpha Avenue. In addition, small quantities of solvents were reportedly used at the two hangars in the north portion of the site. Lear Fan, one of the post-military base industrial tenants with several facilities, may have used solvents in plating operations. Precision Rolled Products on Cocoa Avenue was cited by the NDEP for mishandling sludge containing solvents on their property. Other facilities within the area may also have used solvents in their operations.
Starting in 1994, in response to the discovery of chlorinated solvents in the groundwater and the potential for impacts to drinking water supplied from deep aquifers in the area, certain potentially responsible parties established a cooperative effort to perform site investigations of suspected soil and groundwater contamination. The investigations identified multiple, distinct plumes of chlorinated solvent impact and their potential source area soils that were closely collocated.
