Such nuclear waste disposal wasn't isolated to there.
My parents live fairly closely to Apollo PA, former home of NUMEC, and my dad works with a lot of people who live there. My dad works with a woman who lives literally across the street from the former plant.
NUMEC disposed of their waste by digging 10 trenches with a bulldozer on site, pushing the... Whatever... in and covering it up.
After years of locals campaigning due to very high cancer rates, it finally got Superfund status and the Army Corps of Engineers hired a contractor, around 2012. In 2014, the contractor just up and left. The next day, the army started patrolling the area with assault rifles. The woman could literally see people with rifles watching her kid play in her yard. No one knows what they found, of course, they're not saying.
Considering the company lost 600 pounds of highly enriched uranium in the 60s, well...
https://en.wikipedia.org/wiki/The_Apollo_Affair The wikipedia page hasn't been updated since before the original contractor pulled out- It originally was supposed to be done in 2015 and is now scheduled for 2019 until 2031 and cost over half a billion total. They've kept the area under guard this whole time.
All to cleanup a field in on the edge of a small town in the middle of nowhere.
Of course my dad's coworker's house is completely worthless, despite being pretty nice. No one wants to live across the street from a radioactive military zone. The government should just buy it from her.
