15 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.
15 Inactive Sites
Sites where military cleanup actions are complete, according to the DOD. Note that this status does not necessarily mean the site is no longer hazardous, as many of these sites are put under long-term monitoring or other restrictions.

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 »
