“…Sena et al (2020) studied water quality variations at the Macela reservoir from 2004 to 2014 and observed that the reservoir water throughout this period remained highly saline and hypereutrophic, characterized as a nutrient-enriched environment (N and P) with high algal production and displaying nitrogen as a limiting nutrient for algal production. The main N and P inputs to the reservoir are domestic waste and effluents originating from a variety of small industrial plants (Santos et al, 2013).…”

The geochemical processes that potentially control the chemical characteristics of the waters of three reservoirs located in the state of Sergipe, Northeastern Brazil, were evaluated using the Gibbs diagram, correlation analysis, ionic ratios and geochemical modeling. The results of the reverse geochemical modeling applied between two water samples from each reservoir were in agreement with the observations of the correlation analysis and ionic ratios, which indicated sea salt dissolution, silicate weathering and, to a lesser extent, carbonate dissolution, as the main geochemical processes responsible for the chemical characteristics of the waters of the three reservoirs, also confirming the importance of ion exchange for the Macela and Ribeirópolis reservoirs. These findings therefore suggest that the growing salinization process of the reservoirs is mainly controlled by water-rock interactions and may also be influenced by contributions from evaporation and anthropogenic inputs.
