Project Approach:
One of increasing complexity:
- homogeneous solutions single mineral phases soils
- soil suspensions 1-D soil columns 2-D soil flow systems
Aqueous and solid phase composition determinations
- aqueous composition – ICP; ICP/MS
- solids composition – NMR; XAS; Microscopy; XRD; IR
Columns (1 and 2D) - to identify transport defined processes
- changes in porosity – g-ray attenuation
- reactive transport directed secondary phases (hydrotalcite vs. zeolite)
Contaminants of interest – Cr, Sr, Co, Tc, and U
