Position Summary

RSI is recruiting for an AS&T Intern who will assist personnel in the Environmental Sciences Laboratory (ESL) with setting up and running columns filled with uranium mill tailings from the Rifle, Colorado, Disposal Site. The intern will then assist with geochemical analyses of the column effluent, along with assembling, plotting, and interpreting the resulting data. The goal is to test a potential method (addition of hydroxyapatite) for reducing or even eliminating uranium mobility in mill tailings.
