In this work we simulate the contaminant transport problem in three dimensions that takes place throughout soil of waste disposals. Such problem is modeled by a diffusion-dominated equation. The solution is addressed by using hybridized mixed finite elements for the spatial discretization of the equation. The resulting linear algebraic system is handled by an iterative domain decomposition procedure. This procedure is naturally parallelizable, and permits to implement an algorithm in distributed memory machines in order to save on CPU time. The numerical results from serial and parallel codes are in a good agreement with experimental results, and performance measures indicate that the parallelizable procedure is able to perform an efficient simulation.
