The vials have since been transferred to a secure lab at the federal Centers for Disease Control and Prevention in Atlanta. <div class="fullattribution">Copyright 2014 NPR.

I'm Melissa Block.<p>AUDIE CORNISH, HOST: <p>And I'm Audie Cornish. Syria has handed over the last of its declared chemical weapons. That's according to the world's chemical weapons watchdog. The move is a key step in a deal negotiated last fall, after the U.S. had threatened to conduct airstrikes against Syria. But many questions remain about Syria's use of chemical weapons and whether remnants of its chemical stockpile remain. Joining me to discuss all this is NPR's Geoff Brumfiel.

It is hard to even say that sentence without feeling like you're relating some science fiction tale. But it's true. The ice wall is designed to stop hundreds of tons of radioactive groundwater from leaking into the nearby Pacific Ocean. NPR's Geoff Brumfiel has been covering this story for a long time.
