Apatite Barrier Appears to be Stopping Strontium-90 Migration in Groundwater at Hanford

Annette Cary of the Tri-City Herald has an interesting article on the latest efforts to keep radioactive strontium from reaching the Columbia River. Worth the time, for sure.
"Less radioactive strontium appears to be reaching the banks of the Columbia River at Hanford thanks to an underground chemical barrier still undergoing testing. This spring Fluor Hanford injected a 300-foot-long natural chemical barrier along the river near Hanford's N Reactor as part of a test of technology developed by Pacific Northwest National Laboratory."
