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 signs dig permits deed restrictions deed notices local use ordinances notations in master plan zoning construction permit prohibit, or otherwise manage excavation below a specified depth prohibit sensitive use (e.g. hospital, daycare, school) prohibit or otherwise manage excavation prohibit residential use prohibit installation of drinking water well prohibit agricultural-irrigation-livestock use of groundwater landfill restriction - prohibit activities that would impact the landfill cap (or cover system) and drainage system landfill restriction - prohibit excavation on landfill 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 landfill restriction - restrict plantings that interfere landfill cap or cover system (roots that penetrate the cap or cover system) landfill restriction - restrict vehicular traffic restrict withdrawal or use of groundwater without treatment restrict land use - mitigation area(s) protection prohibit human consumption of groundwater « see less

144 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.

Soil: Low Risk

Explosives from the subsurface soils have been detected in the GW from this area. GW screening data suggets possible perchlorate migration from subsurface soils. Nothing from surface soils are migrating to GW. The site is very small. Constituents of concern are in subsurface soil, not surface soil. Access to potentially impacted wetland area is extremely difficult due to proximity to the installation security fencing and the abundant growth of underbrush.

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 »
