Abstract

The semi-arid region of the Brazilian northeastern has been grieved during the last years by prolonged drought characterized by irregular precipitations and below the historical average for the region. This has led populations to seek new sources of water to meet their needs. One of the most sought sources is groundwater. This was the case of the municipality of Sousa in the state of Paraíba, which, through the City Hall, promoted the drilling of several wells in the urban area of the city. However, no hydrochemical studies were done on the quality of these waters. In this sense, the objective of this work was to evaluate hydrochemically the groundwater of 13 wells in the urban area of the municipality of Sousa-PB from July to December 2017. The parameters pH, electrical conductivity, carbonates, bicarbonates, chlorides, calcium, magnesium, potassium, and sodium. It was verified that the waters of these wells have high dissolved solids contents, having been classified as sodium chlorinated and sodium bicarbonated. Regarding a possible use in agriculture, all the samples presented a risk of high or very high salinization and a risk of sodium ranging from low to very strong.
