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 contaminate1 ground water. And as ice sheets continue to melt2, 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 United3 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. So far the containers seem safe, but there’s always the possibility of corrosion4. So, basically5, there is no best way to store nuclear waste.
