This paper presents a semi-analytic procedure for obtaining solutions of co
ntaminant migration from a deeply buried cylindrical source surrounded by a
pproximately annular zones of material where each of these zones is homogen
eous with its own set of properties. The solution technique involves the us
e of Laplace transform to eliminate the time derivative of the advection-di
spersion equation governing contaminant transport. Solutions are found in t
he Laplace transform space and inverted numerically using an efficient inve
rsion algorithm due to Talbot(1) to obtain the concentrations in real space
and time. Copyright (C) 1999 John Wiley & Sons, Ltd.
