301 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: deed restrictions, local use ordinances, fences. see more » fences guards signs dig permits deed restrictions deed notices local use ordinances notations in master plan zoning education programs construction permit environmental covenants landfill restriction - prohibit activities that would impact the landfill cap (or cover system) and drainage system prohibit sensitive use (e.g. hospital, daycare, school) restrict withdrawal or use of groundwater without treatment prohibit human consumption of groundwater prohibit agricultural-irrigation-livestock use of groundwater prohibit groundwater extraction that interferes with remedial action system prohibit residential use landfill restriction - restrict vehicular traffic prohibit or otherwise manage excavation landfill restriction - prohibit excavation on landfill cap or cover system prohibit installation of drinking water well landfill restriction - restrict plantings that interfere landfill cap or cover system (roots that penetrate the cap or cover system) landfill restriction - prohibit installation of utility system lines through the site landfill restriction - restrict access to the site landfill restriction - restrict construction of buildings that may interfere with landfill cap or cover system prohibit exposure to surface water prohibit exposure to sediments prohibit fishing except for recreational purposes (catch and release) prohibit, or otherwise manage excavation below a specified depth restrict land use - mitigation area(s) protection « see less

94 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 »
