264 Hazardous Sites

Below are the locations of hazardous sites associated with this military installation, according to the DOD. A site’s contamination may affect a much larger area, including public and private lands and the water supplies beneath them.

High Risk

Medium Risk

Low Risk

Risk Not Evaluated or Not Required

Response Complete

We haven't independently confirmed the location of every site. If you notice a site placed at the incorrect location, please contact us.

Not all sites in the DOD data include location information, so there may be sites listed below that are missing from the map. The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.

Land Controls & Restrictions

Many sites have been declared “clean” by the DOD but are still not safe for people. This military installation is safe only with the following conditions in place: fences, dig permits, signs. see more » restrictions on land use dig permits fences notations in master plan restrictions on groundwater withdrawal signs landfill restrict land use - mitigation area(s) protection media specific restriction - ground water « see less

160 Active Sites

Sites where military cleanup actions are still ongoing. The risk level of a site refers to a relative risk assessment made by the DOD, which prioritizes the cleanup of sites that pose greatest threat to safety, human health, and the environment.

Groundwater: Medium Risk

Data from monitoring wells confirms that the plume has migrated away from site, although it is still on-base. SVE and LNAPL recovery have reduced the source area term and limited the potential for further migration. Groundwater not considered for cullinary or agricultural use. No threatened water supply well downgradient. Perched aquifer 50 feet below ground surface above the OU 8 plume area. Vapor intrusion does not appear to be a factor at this site.

Soil: Low Risk

Originally the site had the potential for migration via wind transport of contaminated surface soils. However a removal action of all surface and near surface soils above 1 ppm, down to a depth of 4 feet has reduced that risk. Digging restrictions are in place and a removal action of surface soils to 4 ft, greatly limited the potential for residents to be exposed to concentrations that could cause a health concern.

Contaminated Areas

Groundwater: Low Risk

Original migration of the plume from source area contaminated 25 acres of ground water off base. Source zone control (low perm wall, extraction wells) and an off-base interception trench have confined the area of contamination. Historically, residences had used the springs for irrigation and livestock. Groundwater is not considered a potential source of drinking water. Alternate sources of clean water for irrigation and or livestock have been provided where required.

Contaminants: 1,2-Dichlorobenzene 120.0 ug/L Bis(2-Ethylhexyl)Phthalate 460.0 ug/L 1,1,2-Trichloroethane 4500.0 ug/L Toluene 10500.0 ug/L Tetrachloroethylene 43500.0 ug/L Trichlorofluoromethane 53000.0 ug/L Methylene Chloride 175000.0 ug/L 1,1,1-Trichloroethane 180000.0 ug/L Trichloroethylene (TCE) 216000.0 ug/L

Soil: Low Risk

Soil contamination found only below the former disposal trenches. no known receptors

Contaminants: Trichloroethylene (TCE) 0.88 mg/kg

Surface Water: Low Risk

Contaminants were originally detected in off base springs 1000s of feet from the source area. These have since dried up due to construction of an interception trench and are no longer a potential exposure point. All contaminated springs currently have collection/treatment to eliminate exposure.

Contaminants: Nickel (soluble salts) 0.0 ug/L Cadmium and compounds 3.0 ug/L 1,2-Dichloroethylene (trans) 14.0 ug/L Lead 80.0 ug/L Tetrachloroethylene 1900.0 ug/L Methylene Chloride 4300.0 ug/L 1,1,1-Trichloroethane 11000.0 ug/L Trichloroethylene (TCE) 170000.0 ug/L

Contaminants detected in the sediment are confined to sediments in the bottom of the pond. Human receptors could possibly come in contact with the sediments. However, likelyhood of exposure is limited.

Contaminants: 1,2-Dichloroethene 1.5e-05 mg/kg p,p-Dimethylamino diphenylmethane 2.3e-05 mg/kg Benzo(g,h,i)Perylene 0.00155 mg/kg Benz(a)Anthracene 0.00224 mg/kg Benzo(a)Pyrene 0.00245 mg/kg Benzo(b)Fluoranthene 0.00337 mg/kg Arsenic 0.115 mg/kg

Surface Water: Low Risk

Water is released from the pond outlet into Kays creek during high runoff periods. Storm water discharge requirements are satisfied prior to release. Human receptors could possibly come in contact with the surface water. However, likelyhood of exposure is limited.

Contaminants: Benzo(a)Pyrene 0.27 ug/L Cadmium and compounds 18.0 ug/L

Surface Water (Fresh): Low Risk

Water is released from the pond outlet into Kays creek during high runoff periods. Storm water discharge requirements are satisfied prior to release. Fish (Bass) and ducks are both present at pond 3.

Contaminants: Benzo(a)Pyrene 0.27 ug/L Cadmium and compounds 18.0 ug/L

Dec 2010

This site is under ongoing monitoring until Sep 2099

Contaminated Areas

Groundwater: Low Risk

Contamination has migrated to groundwater at low concentrations. Very poor gw quality in the area and water table is 150' below ground surface. GW in area of plume not used for any purpose.

Contaminants: Trichloroethylene (TCE) 17.0 ug/L

Soil: Low Risk

Concentrations vary with depth - indicate contaminants traveling through the vadose zone. Model was done to determine estimated time of travel to the GW. Is potential for range personnel to access the site, however soils contamination is not on the ground surface. Unlikely that workers would ever come in contact with contamination.

Contaminants: 1,1,1-Trichloroethane 8.3e-07 mg/kg Cadmium and compounds 0.0011 mg/kg Tetrachloroethylene 0.0028 mg/kg Arsenic 0.0035 mg/kg Trichloroethylene (TCE) 0.0052 mg/kg Bis(2-Ethylhexyl)Phthalate 0.0062 mg/kg Copper and compounds 0.007 mg/kg Toluene 0.0079 mg/kg Vanadium 0.017 mg/kg Lead 0.0186 mg/kg Xylene (Mixed) 0.031 mg/kg Barium 0.154 mg/kg Manganese and compounds 0.172 mg/kg Iron 6.91 mg/kg

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 »
