In this talk we identify the stochastic process governing the motion of molecules in a solute diffusing in a one-dimensional medium with piecewise constant diffusion coefficient. The process turns out to be a generalization of skew Brownian motion to the case of several interfaces. We give some background on novel tools required to make the connection between the stochastic process at the microscopic scale and the partial differential equations in the macroscopical model Finally, properties of the stochastic process are used to study the transport of solutes in rock with periodical cracks.
