97 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, fences, warning signs. see more » a deed restriction is documented in the parcel deed. a warning sign is in place surrounding the area a fence around controlled area, with or without gate. a barrier, including but not limited to a paved surface or landfill cap, must be maintained in order to prevent exposure to contaminants, including vapor intrusion into an enclosed structure. notice to federal or state regulators, property owners, etc. before changes in land use or ownership. gate(s) and/or door(s) must be locked to prevent access and exposure to contaminants. notices other than in deed, e.g., newspaper advertisements. 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 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. groundwater use restricted. prohibits access, 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. prohibit removal or breaching of existing exposure barriers (e.g. concrete blding foundations, surfaced parking lots, and other paved surfaces), unless prior written approval of the navy and lead regulatory agency is obtained. prohibit fishing or consumption of fish. « see less
4 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 »
