A. For conservative solute transport, explain the physical difference between mechanical dispersion and molecular diffusion using diagrams in your answer as appropriate. Provide an example of conditions in a groundwater system where each of these two mechanisms would be dominant over the other.

B) In conservative solute transport, is the mechanical dispersion coefficient a constant value in all groundwater systems? Explain.

c). Explain the difference between the groundwater transport behavior of a conservative dissolved contaminant and a reactive dissolved contaminant. How is the term ‘retarded’ used within the context of the mobility of different groundwater contaminants?
