Following a Lagrangian framework the biodegradation process along the single streamline is numerically solved by the method of the characteristics, where the heterogeneity is taken in account by the particle displacement statistics concerning the passive solute. This technique gives relevant advantages, since the space-time evolution of reactive solutes can be deduced on the knowledge of the passive solute displacement statistics with a limited computational effort. Moreover the numerical procedure allows us to define the va
