This work was mainly focused on assessing the water quality of the aquifer Bauru in the city of Araguari, MG and verification of any changes related to the loss of water quality. The survey was based upon assessment of quality parameters of water samples extracted from wells. The wells were carefully chosen due their functionality within water supply system These analysis were combined with simulations of particle trajectories. The analyzed parameters can be related with pollution from sewage, with the diffuse input of fertilizers and with the presence of suspended solids. In this context, were analyzed the parameters nitrate, nitrite, pH, total phosphorus, COD, BOD, color, turbidity, coliform organisms and, finally, the series of solids. Considering the results for each individual water quality parameter, a correlation analysis was carried out. Computational simulations were used to locate the likely origin of substances found in wells. The results of water quality analyzes and simulations of particle trajectories indicate that sewage leaks, especially when occurring in zones whose natural vulnerability indices are higher, may be the cause of the presence of substances such as nitrate and volatile solids in some wells.
