Recent two dimensional nuclear magnetic resonance (NMR) techniques access exchange in
pore structures through surface relaxation and diffusion based relaxation [1-4]. This research
applies these techniques to measure pore changes due to biofilm growth and the impact this
growth has on diffusion transport. The porous media used in this study are model beadpacks
constructed from borosilicate glass beads with diameters approximately 100 µm. This
research shows that through changes in the relaxation rates, NMR can be used to verify
biofilm growth in porous media
