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: deed restrictions. see more » annual written certification of compliance with lucs a deed restriction is documented in the parcel deed. prohibit construction and/or operation of businesses, structures or other areas frequented by sensitive populations, such as children and the elderly, unless prior written approval of the navy and lead regulatory agency is obtained. prohibit residential use in certain areas, unless prior written approval of the navy and lead regulatory agency is obtained. groundwater use restricted. prohibits the disturbance or use of existing groundwater wells, unless prior written approval of the navy and lead regulatory agency is obtained. prohibits disturbance of surface or subsurface soil due to invasive activities such as construction, unless prior written approval of the navy and lead regulatory agency is obtained. « see less
5 Active Sites

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 »
