We analyze the shape of breakthrough curves (BTCs). In general, monotonicity of the late-time BTC slope is just assumed. We contend that local peaks may exist but are sometimes not reported for a number of reasons: in the field, either by subsampling or associating them measurement errors; in numerical simulations, from numerical dispersion in Eulerian methods, or from the use of a limited number of particles in Lagrangian methods. The presence of localized peaks in BTCs (when, at what magnitude...
