The site show pictures of bacteria that converts uranium wast in water into solids. Yes, you now have radioative bacteria. But,This is easier to handle. (I hope) What I just said sounds like a 50s SF movie. With all the nuclear subs discussed on this site, I thought that this would be of interest

This bacteria is able to survive in radioactive environments and turn the uranium waste from a soluble form (that can contaminate water supplies) to a solid form.
Picture one of these things climbing up the Empire State Building.
