https://goldcountr...nation-has-spread/ The moral of this story is that the Lincoln site, and by logical extension, the others as-well are a very serious (albeit mostly unaddressed) issue for the property owners, adjacent property owners, and any intelligent person with a business or residence in the area. None of us would want to deal with the anxiety of wondering if the drinking water we & are family use is safe, the water used to make the dough at our pizza or doughnut shop is safe, if our home or business has any re-sale value due to the groundwater contamination issue, etc.
So it's pretty understandable if the site owners, neighbors, etc. are already having a bad day when they see you poking-around on or near the site and thus not likely to appreciate your adventuresome spirit, etc. Army Corps of Engineers (contractors) come-around as they get project funding available. Sometimes they do half the job, then funding runs-out or they get pulled to a higher priority project, and maybe come back 2 years later to do a little more work... It gets political, always contentious and usually a decades-long fiasco (look at the former Hunter's Point Naval Ship Yard -- they've got something somewhat scarier -- ionizing radiation).
The reality is that just about every 20th century US military site does or did have some level of soil contamination. Sounds crazy by today's standards, but back in the day, gasoline was a cleaning solvent to cut through grease & grime. Got some nuts & bolts or other tank parts? Soak 'em in a bucket or barrel full of gas, then just dump the gas out onto the ground somewhere convenient! Also poured onto a rag & used to hand-wash cars, jeeps and just about every other grimy metal item that didn't have high-gloss paint...
