The site is composed of 102,062 acres and had numerous improvements, including Quonset huts, wood frame structures, reinforced concrete structures, Bunkers, docks, hangers, fuel storage facilities, an airstrip, and numerous other support facilities. The site consisted of a main cantonment area and two satellite areas. The site is owned by the State of Alaska and three native corporations. This property is known or suspected to contain military munitions and explosives of concern (e.g., unexploded ordnance) and therefore may present an explosive hazard.

Contaminated Areas
Surface Water (Fresh): High Risk
Already in the watershed. Analytical data indicates that contaminants in surface water are present at a point of exposure for a surface water receptor. Receptors have been specifically identified as having access to surface water or sediment to which the contaminants have moved. This includes the use of water as drinking water, for watering livestock. Main water source for livestock on the ranch.
Contaminants: Acrolein 880.0 ug/L
Surface Water (Human): High Risk
Already in the watershed. Analytical data indicates that contaminants in surface water are present at a point of exposure for a surface water receptor. Potential for use is thought to exist because of nearby populations. Site visitors use the water for drinking water source.
Contaminants: Acetone 670.0 ug/L Acrolein 880.0 ug/L
Soil: Medium Risk
Analytical data and direct observation indicates that contamination is present at a point of exposure. There are no workplaces, residences, schools, or daycare centers in the area of contamination, but access is not restricted. Cattle and ranch hands may be exposed to contaminants

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.
Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
Data: All data comes from the Defense Environmental Restoration Program and the U.S. Army Corps of Engineers, and will be released soon at the ProPublica Data Store. Read our methodology »
