The authors show exact analytic solutions for hydrogeologic transport of contaminants from an array of point sources in a waste disposal site, and contaminants released from finite areal sources into a planar fracture. For dispersion from an array of sources, dispersion may be isotropic or anisotropic, and equilibrium sorption and radioactive decay are considered. For contaminant released into a fracture, the solution includes the effects of advection in the fracture, transverse dispersion and surface sorption, as well as diffusion into and sorption in the rock matrix. The authors illustrate the solutions through numerical and graphical displays of the spatial and temporal distribution of the contaminant. The numerical illustrations show that at a certain distance away from the sources, indicated by a distance parameter, equivalent single-source solutions give acceptable approximations.
