Often, dynamic patterns are constructed from the concatenation of the patterns identified on each state of the process. In this work it is shown that the interpretation of dynamic patterns can not be constructed as a simple concatenation of the concepts associated to the components of the dynamic process. This phenomenon is defined as a Paradox of the Mitigant Trajectories (PTM). A method to identify PTM's is proposed as well as a method to correct them. Also, the proposal is applied to a Wastewater Treatment Plant (WWTP). The correct interpretation of dynamic patterns is crucial as inducted knowledge to be considered for an input to Intelligent Environmental Decision Support Systems (IEDSS).
