Journalist Jeremy Shere describes the problems with most methods of nuclear storage:  "There have been a few other interesting ideas –such as burying nuclear waste beneath the ocean floor. Scientists have also thought about putting waste in really deep holes, burying it in polar ice sheets, and stashing it beneath uninhabited islands. [...] But there are problems with each of these ideas. For example, it would be difficult to monitor nuclear waste under the ocean floor. Waste buried deep in the earth, meanwhile, might contaminate ground water. And as ice sheets continue to melt, it’s hard to say how long nuclear waste would remain buried, or where it would end up if it floated away. Plans to store waste produced in the United States in Yucca Mountain, in Utah, have been put on hold. So for now almost all nuclear waste is kept above ground in special containers at a few hundred different sites around the country.”1  The point with underground nuclear storage is that geological conditions are often very different between states and regions; this would often mean that in some states underground nuclear storage would be completely inappropriate because it could leak due to geological changes. Further, underground nuclear storage as mentioned in the first opposition counter-argument, actively encourages a state to become reliant on nuclear power.
