https://ags02.sec....c5b960eb1cf9145738 The web page above takes you to a great GIS map of major & minor DERP-FUDS sites around the USA.
The US Army Corps of Engineers Defense Environmental restoration program - Formerly Used Defense Sites ("DERP-FUDS") is responsible for the evaluation & cleanup of all property that was under DOD control (meaning both DOD-owned as well as leased or otherwise used) & became surplus prior to 1986. Due to the number of small and large sites around the country and the expenses involved in properly remediating them, it's been an on-going effort for decades, and especially with some large sites, the efforts are piecemeal a certain budget is allocated each year to do different problem (such as unexploded ordnance) or different parcel of a site. *IF* the site was sold-off and the contaminated structure or area was beneficially re-used, the responsibility for environmental cleanup belongs to the person or business that was using the property, not USACE DERP-FUDS, so the site may not show-up on the above GIS map.
Understand that USACE DERP-FUDS doesn't have a broad historical interest in the site, it's just to determine that the property was indeed used by DOD, disposed-of before 1986, and then a basic understanding of what the DOD did with the property, in order to determine what environmental contaminants -- toxic materials, live ordnance, etc. may remain, and where they may be, so don't expect a lot of detailed & accurate overall information about a site.
