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 »
