The university is located in Yolo County, California on County Road 31 and is approximately twenty miles west of Sacramento and five miles northwest of Davis. The Yolo County Airport is approximately 1.75 miles northeast from the university (Maptech, 2000). The site is located on approximately 651 acres and 5 miles northeast of Winters in Yolo County. The site is now owned by Native Americans and used for Deganawidah-Quetzalcoatl University, Inc. as well as Yolo County for use in highway purposes.During its use as a support for the Corps Radio Station WVY, the Army constructed a communications building, barracks, storehouses, water pump plants, two incinerators, utilities, six underground storage tanks (USTs), twenty-two transformers, two wastewater oxidation lagoons (WOLs), two cooling water injection wells, and one water supply well. At the time of quitclaim, the site contained all of the original buildings, most of the generating and pumping machinery, two WOLs, two cooling water injection wells, six USTs, five above ground storage tanks (ASTs), and thirteen transformers. The six main buildings located on the site were used by the Army for dormitories, administration, maintenance support, and housing for intercontinental radio receivers and transmitters. D-Q University now used these buildings as classrooms, dormitories, an administrative office, a cultural art center, and for other school associated purposes. The university is enclosed by a chain link fence and surrounded by agricultural fields. There are no structures located within a 1-mile radius other than those associated with the site or farming activities. (Source: U.S. Army Corps of Engineers) « see less

Contaminated Areas
Groundwater: Medium Risk
The only movement of groundwater is within the perched water layer and at a low flow rate since the release. However, low concentrations have been detected approximately 2,500 feet downgradient in monitoring wells. Contaminated groundwater table is perched and has no interconnection to adjacent aquiffers. There is no potentially threatened water supply well downgradient of the source and the groundwater is not considered a potential source of drinking water and is of limited beneficial use. Class IIIB water source.
Contaminants: Vinyl chloride (child/adult) 6.8 ug/L 1,2-Dichloroethylene (cis) 37.0 ug/L Trichloroethylene (TCE) 230.0 ug/L

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
