Abstract
The use of lead in pipe networks, and the subsequent lead emissions into
drinking water, is now a major concern to the European Union Member States.
Computer simulation offers the possibility for achieving a greater understanding
of the issues that relate to plumbosolvency control. An analytical and a
numerical scheme for the diffusion of lead into drinking water within a pipe
during a stagnation period are described. These have been validated by
experimental work. Three models have been investigated to simulate the flow of
water through a pipe. These flow models have been used in conjunction with the
equation of mass transfer to simulate the concentration of lead at the tap. This
has been used within a Monte Carlo framework in order to simulate a zone of
properties. The zo
