Chemical Barrier Will Protect River From Strontium

RICHLAND, Wash.- Fluor Hanford is using a previously tested technology to install a 300-foot apatite barrier along the Columbia River shoreline near Hanford's N Reactor.

The calcium phosphate chemical is being injected into wells along the shoreline with the hopes it will bond to and encapsulate radioactive Strontium-90 in the groundwater.

The apatite should turn it into a solid that will allow the strontium to deteriorate before it escapes the solid.

Fluor is also looking at planting trees near the shoreline with roots that will penetrate the groundwater and soak up strontium.
