| Popis: | Water abstraction from phreatic aquifers allows easy access at low cost. However, these waters’ direct consumption can be harmful, especially in unsewered areas where domestic effluents are discharged into cesspits. This study assesses the quality of the groundwater explored by the Guriri beach resort residents. Samples from 35 residential wells were characterized, considering physicochemical and microbiological parameters. The water balance (rainfall–evapotranspiration), proximity to the shoreline, and separation between the well and the cesspit were taken into account in the interpretations. The evaluation with statistical tests (mean and correlation), graphs (Piper and Gibbs), and multivariate techniques (PCA and HCA) allowed the separation of two chemically distinct groups of waters. One from shallow wells (3 to 4 m depth) with lower electrical conductivity (EC) and acidic characteristics and the other gathering the deeper wells (11 to 13 m) with higher EC and neutral pH. All samples were classified as freshwater (TDS |
