Question 2
What is the primary mechanism by which non-aqueous phase liquids (NAPLs) move through the subsurface?
Question 3
Which parameter in the advection-dispersion equation accounts for the spreading of a contaminant plume due to both molecular diffusion and variations in groundwater velocity?
Question 4
