What is it about?
This is a mathematical model of an environmentally relevant problem - the removal of heavy metal from buried cylindrical concrete waste forms in soil. The heavy metal can be leached from the buried and supposed contained samples into water. As it turns out, certain biological systems (acid forming) can enter the contained samples and render them leak-able so the contained material can be leached out into water.

Why is it important?
The mathematical model addressed an approach that can be used to predict the concentrations that may be leachable into adjacent soil. The model takes into account the notion of heterogeneous chemical reaction and demonstrates how to derive analytical solution exclusive of statistics.
Perspectives
The approach used in deriving a closed form solution emphasizes the underlying transport phenomena while exposing the type of mathematics encountered in undergraduate calculus courses. It serves as a reason for including such math courses and how they might be used to solve relevant practical problems.
