heal.abstract	The aim of this article is to predict, through reactive transport modeling, the progress of the reaction front in lignite-based fly ash permeable reactive barriers by taking into account media compositional changes and degradation rates as well as the drop in reactivity due to precipitation and clogging, metal ion concentration, and removal mechanisms. In order to simulate field conditions, synthetic solutions with the quality of leachates generated at waste disposal sites (in terms of pH and toxic load) were pumped upflow in two 40-cm-long laboratory columns placed in series. In addition, this article aims to introduce engineering and science tools in understanding the mechanisms and the geochemical processes that determine the fate of contaminants during migration of acidic plumes in environmental media. The following methodological approach may be helpful in forensic investigations aiming to establish the contamination history at waste disposal sites. Copyright © Taylor & Francis Group, LLC.	en
