Regarding uranium extraction in Czechoslovakia, the Soviets later mined uranium in other sites by pumping sulfuric acid into the ground. This has caused a lasting ecological damage which has to be managed to this day. The acid was meant to dissolve the ore and was then sucked back out. The only issue was that they ended up pumping a more sulfuric acid into the ground than sucking out. This created an underground lake of sulfuric acid in an with other underground water "lakes". This sulfuric lake is threatening to spill into these water sources. I heard about this from my teachers at the university who were involved in the modelling of the underground spill. Using a limited number of wells, they were supposed to predict how the spill is spreading and what actions to take to stop it. I found some pictures from the site here: https://zpravy.aktualne.cz/domaci/pitna-voda-tezba-uranu-kyselina-ekologicka-zatez/r~i:gallery:15715/r~i:photo:319256/ https://zpravy.aktualne.cz/domaci/pitna-voda-tezba-uranu-kys...
