“…The lowest potentiometric levels of the SGAS are recorded in the extreme west of Paraná state close to the Paraná River, which is a mixing zone (Athayde, et al, 2012). Bongiolo, et al, (2011) showed that there are compositional differences between distinct compartments in the state of Paraná.…”

“…Samples richer in some variables that had similar characteristics to each other were associated with a specific component in the R-mode (variable grouping) cluster analysis. The same factorial technique for analyzing a complex data set that needed to be reduced in terms of variables was used in Bongiolo, et al, (2011). The main component technique was applied to a set of 45 samples studied for nine variables: pH, STD, HCO3 -, Cl -, SiO2, Ca + 2 , Mg + 2 , Na + and K + .…”

“…This same evolutionary pattern described previously based on hierarchy cluster analyses, confirming the existence of three major groups. One belongs to deep confined groundwaters of alcaline, SO4 -2 , Clcomposition, another to the intermediate zone of high pH and Na + -HCO3composition and the last one in the recharge zone of Ca +2 -HCO3composition with acidic pH (Hirata, et al, 2011;Bongiolo, et al, 2011). In Rio Grande do Sul state, through K-means technique, there are typically three groundwater chemical groups in each of the five SGAS compartments in the state, and the most salinized of the groups had influence of GAS and Pre-GAS units (Teixeira, et al, 2021).…”

The Paraná Basin in Brazil is of vital importance and because of a large groundwater reservoir and the high exploitation of this resource by the population a structural and hydrogeochemical knowledge is needed. Objectives: 1) Analyze studies that address the structural, hydrogeological and hydrochemical characterization of aquifers in the Paraná Basin; 2) Highlight the main techniques used in the respective studies and the scientific development arising from the use of these techniques for a better hydrochemical and structural understanding of the Paraná Basin. Methodology: Tracing lineaments from satellite image and field work are the main techniques used for structural characterization. For hydrochemical analyses, factorial methods physical-chemical analyses are used. Results: the most common chemical types of groundwater that circulate in the sedimentary and volcanic units of the Paraná Basin, which include the Pirambóia, Irati, Rio Bonito, Botucatu and Serra Geral formations are calciumbicarbonates, calcium-magnesian bicarbonates, calcium-sodium bicarbonates and sodium-sulphate-chloride bicarbonates. Sodium-sulfated waters are not found in the Serra Geral Formation, except when they come from the sedimentary units. Sodium and sulfate are not expected ions in basalt weathering, and therefore a greater understanding is needed on structural communication by means of faults that occur between the Serra Geral Aquifer System (SGAS) and the mesozoic and permian sedimentary aquifers and aquitards that contribute for unexpected ions in the SGAS. Conclusion: The Paraná Basin is a reason for interest in geological studies in Brazil because of its link to several areas of interest in geosciences, which include hydrochemistry, stratigraphy, paleontology and hydrogeology.

“…The sandy rocks saturated with water are interspersed with the intrusion of basaltic rocks of the Serra Geral Formation. The thickness of this sandy rock pack ranges from 200 to 800 m, reaching up to 1,800 m depth in the states of São Paulo and Paraná (Bongiolo et al 2011, Fioravanti 2010. The basaltic lava spill of Serra Geral Formation serves as a cap to the Paraná Basin.…”

This paper estimated the total water storage variation in the southern rim of the Guarani Aquifer System during a three-year time span, making use of data provided by the Gravity Recovery and Climate Experiment. Monthly data were used to estimate the Bouguer anomaly in Southern Brazil. A direct modeling, using the Bouguer plateau, was applied to quantitatively estimate the water volume variation of a specific thickness in the studied region. Meteorological almanac data were compared to the gravitational alterations. We found a direct proportionality between the monthly rain average and the water table level. A simple model was found to forecast water accumulation as a function of rainfall regime, which is validated by a Pearson index of 0.82 that indicates a strong correlation between pluviometric and gravimetric data. In order to raise the stored water level near the recharge area by 1 mm, approximately 3 mm of rainfall is needed.
