But when shell collides with armor, fine particles scatter, so the military use of depleted uranium has left soil and water tables in battlegrounds polluted. Although less radioactive than natural uranium, the depleted form is nonetheless toxic and as hazardous as lead or mercury.

It tends to be soluable when it is in its oxidized state. Once it gets into an anoxic part of an aquifer, it precipitates out of solution.

"So in laboratory experiments, they fed depleted uranium to so-called mycorrhizal fungi, which usually live in the roots of plants, taking carbon from the plants and furnishing nutrients in return. Within a few months, the team reports tomorrow in Current Biology, the mycorrhizal fungi had surrounded and chemically transformed the depleted uranium to a stable phosphate compound.

Key words there. We need do nothing at all, it's already present and working to neutralize all this "evil" DU, evil only because it has the word "uranium" in it, and we happen to make and use it to protect our troops from terrorist RPG attacks.
