When I was a kid, I was taught to clean up after myself. But uranium companies haven't figured that out.
There are 272 old uranium mines and prospects in South Dakota. The vast majority have never been cleaned up, and some of them are over 50 years old.
Multiple studies done by School of Mines professors and graduate students show that these old mines are putting contamination into our water. They're polluting the Moreau, Grand, and Cheyenne River watersheds.
Besides mines, companies also left old drill holes, mine shafts, and even holes large enough for a person to fall into in the southern Hills. One picture in a School of Mines study shows someone dangling his feet into a hole large enough for two people to fall into.
So why should we let uranium companies start mining in the Black Hills again? Haven't we learned our lesson?
I sure hope so.
