Groundwater is a large percentage of sweet easily accessible water and is often the only option for drinking water supply. In general, it possesses better quality due to interactions with the ground during percolation. In urban areas, however, various activities compromise its quality and demand, such as installation of black tanks, wastewater without treatment or with inadequate treatment, improper disposal of solid waste, waterproofing recharge areas, storage of dangerous products in underground or air tanks without basin containment, among others. The aim of this study was to evaluate the contamination of the unconfined aquifer in the North Zone of Aracaju, SE, through the analysis of physical, chemical and biological parameters of water samples from shallow wells, relating to potential sources of contamination, evaluating the effects of seasonality and comparing them to the limits of potability of Decree No. 2,914 / 2011 of the Ministry of Health, the results show that all samples were unfit for human consumption for at least one of the 13 analyzed parameters, with the most significant change in the dry season.
