Aquifers underground computational models can be built to help the decision making on water resource management, simulating varied situation in adverse conditions, in order to propose environmental accidents solutions, such as contamination by toxic substances problems that affect the consumed water quality. Computer models for aquifers consider the water disposal in porous medium and contaminants transport in the water. Rapprochement models and time and space discretization, as the finite differences model, finite volume and element are generally used for this purpose. This work presents a methodology involving computer simulations by the finite elements method and parallelized genetic algorithm , in order to select the most appropriate solution in well remediation allocation, which will withdraw the contaminated water from the aquifer. It was taken into account the financial cost as a restriction of the sought depollution and the objective function is to minimize the cost and increase the pollutant reduction, considering area restrictions for wells allocation, variation in the number of wells and ability to pumping in each.
