Our objective was to evaluate the physicochemical parameters of waste brine from reverse osmosis desalination plants and to evaluate the physicochemical parameters of soils where it is discharged in rural communities in the western Potiguar region of the state of Rio Grande do Norte, Brazil. Soil samples of two types (Eutrophic Red Argisol and Fluvic Neosol) were collected in the dry and rainy seasons in two communities at two distances from the discharge point (1 and 2 m) and at the point itself, in two layers for each point (0–20 and 20–40 cm). In addition, samples of waste brine were taken from the desalination plants for the evaluation of the physicochemical quality and contamination risks. All brine samples were classified as C3 or C4, which is, extremely high risk of salinization, needing special practices for salinity control. The two soils that received the brine presented significant alterations of their attributes and quality throughout the periods. This was more pronounced in the dry season and the layers of soils with a greater amount of clay, which resulted in the soil receiving different classifications, which were influenced directly by the brine.
