Análise da qualidade da água subterrânea para abastecimento público: estudo de caso na comunidade Alto do ferrão, em Itaiçaba-CE.

Abstract

In Brazil, groundwater is explored through wells popularly known as artesian or semi-arty wells. The exploitation of this resource has increased more and more due to the low cost invested in the extraction of water in the subsoil. A large part of the Brazilian population does not have access to piped water, leading them to resort to this resource. However, there is a concern to investigate the quality of these waters, considering that they may be contaminated by anthropic action or not have natural quality for consumption without prior treatment. This work aimed to analyze the quality of groundwater in the Alto do Ferrão community in Itaiçaba- CE. For the diagnosis of water consumed in the community, physical-chemical and microbiological parameters were analyzed, according to the minimum investigation carried out by the state water company. The research was carried out in two water collection campaigns to later determine the parameters and evaluate the existence of the available treatment. It can be seen that the pH parameters and total dissolved solids were in accordance with the current legislation while turbidity and color exceeded the limit established by the norm. In the microbiological analysis, the presence of total coliforms in the water was found. With respect to the existing treatment, it consists only of the filtering process. Therefore, it can be concluded that the water available is not suitable for consumption in its raw form or with the current treatment system.
