    Even if our planet is filled with water, the potable portion is very small in comparison to all existing water, besides an irregular distribution among the population, and suffering more and more degradation by man, due to industrialization, agriculture, for example. Several parameters are analyzed for this to be accomplished, and based on this, this work analyzed the physical, chemical and microbiological parameters of the treatment plant (ETA) of the municipality of Bandeirantes – PR at its six catchment points (Rio das Cinzas – RC, four points of the Guarani Aquifer – AG1, AG2, AG3 and AG4 and Poço Artesiano Sertãozinho – PAS), comparing the seasons of the year in three consecutive years. pH, turbidity, organic matter, color, heterotrophic bacteria, total and fecal coliforms were evaluated. The results demonstrated, for example, that the RC point presented pH close to neutrality, while in the PAS point it had a range of 6.9 to 8.0 and in the aquifers values with higher pH between 8.0 and 9.6, that is, also higher in comparison to the RC point. Alkalinity was higher in the aquifers with intervals of 75–163 mg/L CaCO₃ between them, and PAS ranged from 109–130 mg/L CaCO₃ compared to RC, which had values of 46–55 mg/L CaCO₃, which is related to the higher pH and the high alkalinity of the aquifers. In the same way, dissolved oxygen with values at the RC point obtained higher values ranging from 5.45–16.2 mg/L, while in aquifers AG1, AG2, AG3 and AG4 obtained smaller values with intervals between 0.56–8.50 mg/L, and PAS ranged from 4.39–14.9 mg/L, due to the depth and high temperatures of these sites. In addition, data from the analysis of pesticides in water proved to be satisfactory under the legislation. It is concluded with this study that the RC point needs a more complex treatment for its use destined to the consumption of the population of the municipality in question.
