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: warning signs, signs. see more » incorporation of lucs into a base master plan notice to federal or state regulators, property owners, etc. before changes in land use or ownership. a warning sign is in place surrounding the area annual written certification of compliance with lucs groundwater use restricted. 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. prohibit residential use in certain areas, unless prior written approval of the navy and lead regulatory agency is obtained. a landfill cover at the site prevents exposure to contaminated soil and reduces infiltration of groundwater. this cover will be inspected and maintained. 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 sediment, unless prior written approval of the navy and lead regulatory agency is obtained. no recreational use, including camping and overnight stays, are permitted in the area. 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. prohibits any use other than industrial in certain areas, unless prior written approval of the navy and lead regulatory agency is obtained. « see less
37 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.

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 »
