Composição isotópica – δ18o e δd – das águas do sistema aquífero Bauru no Estado de São Paulo

Geociências (São Paulo) (2016)

Márcia Regina Stradioto Chang Hung Kiang

Environmental isotopes, particularly δ 18 O e δD, provide important information on groundwater origin, mixture of different groundwater and aquifer recharge. The present study presents the results of isotope ratio of δ 18 O e de δD for groundwater of Bauru Aquifer System (SAB), as well as their distribution over the aquifer units occurring in the state of Sao Paulo. The study was performed using water samples collected in previously selected wells in the outcrop areas of the Bauru Group in Sao Paulo. Statistical analysis was useful to test isotope ratios similarities among the major aquifer units, using 339 groundwater samples distributed over the entire area of occurrence of SAB in the state of Sao Paulo. Isotope ratios vary from –8,94‰ to –3,55‰ for δ 18 O and from –62,5‰ to –25,4‰ for δD with the values falling closely along the Global Meteoric Water Line.

Geochemical evolution, residence times and recharge conditions of the multilayered Tubarão aquifer system (State of São Paulo – Brazil) as indicated by hydrochemical, stable isotope and¹⁴C data

Isotopes in Environmental and Health Studies (2020)

Sibele Ezaki Didier Gastmans Mara Akie Iritani Vinícius dos Santos Márcia Regina Stradioto

The Tubarão aquifer system constitutes a very complex, multilayered aquifer enclosed in the Paraná basin (central-southern part of Brazil). Despite the relatively low productivity of wells, groundwater represents an important source of water for the very populated and industrialized zones of the State of São Paulo. An extensive water sampling campaign was carried out followed by hydrochemical and isotopic (δ2H, δ18O, δ13C and 14C) studies, aiming at a better understanding of the aquifer's geochemical evolution, recharge processes, and its groundwater residence times. Two main hydrochemical facies were recognized and divide the aquifer in two portions. The shallow portion – the active hydrological zone of the aquifer – is characterized by the Ca-HCO3 water type, evolving as a system open to atmospheric CO2. Mean residence times are typically lower than 5000 years. The lower portion is mostly characterized by the stagnant, Na-HCO3 water type, evolving under closed system conditions. Residence times average up to 15,000 years, but can reach 44,000 years, which indicates the exploitation of (possibly non-renewable) fossil waters. This study contributes to the establishment of proper policies regarding the sustainable groundwater exploitation of the Tubarão aquifer system.

Water-Rock Interactions in the Bauru Aquifer System – São Paulo State, Brazil

Procedia Earth and Planetary Science (2017)

Márcia Regina Stradioto Elias Hideo Teramoto Maria Rita Caetano-Chang Chang Hung Kiang

The study focuses on the assessment of mineral saturation indexes using data of physicochemical analysis of groundwater samples from different units of the Bauru Aquifer System, in the State of São Paulo, Brazil. The analysis revealed that calcite (CaCO3) undersaturated waters dominate in the aquifer, but eventually groundwater reaches saturation with respect to this mineral. The majority of water samples are supersaturated with quartz, SiO2, and undersaturated with amorphous silica, SiO2(am). In the equilibrium diagrams, the samples are predominantly concentrated in the stability fields of the kaolinite and montmorillonite, which indicates that these mineral phases are the most probable sinks for Si and Al derived from weathered aluminosilicates.

Despite the relatively low productivity of wells, groundwater represents an important source of water for the very populated and industrialized zones of the State of São Paulo. An extensive water sampling campaign was carried out followed by hydrochemical and isotopic (δ²H, δ¹⁸O, δ¹³C and ¹⁴C) studies, aiming at a better understanding of the aquifer's geochemical evolution, recharge processes, and its groundwater residence times. Two main hydrochemical facies were recognized and divide the aquifer in two portions. The shallow portion – the active hydrological zone of the aquifer – is characterized by the Ca-HCO₃ water type, evolving as a system open to atmospheric CO₂.

Sucessão sedimentar do Grupo Bauru na região de Pirapozinho (SP)

Geociencias (Sao Paulo) (2006)

Flávio de Paula e Silva Chang Hung Kiang Maria Rita Caetano-Chang Márcia Regina Stradioto

There is yet enthusiastic debate in the literature about the environmental conditions that originated the Cretaceous deposits of the Bauru Group, despite many authors accept that arid climatic conditions widely dominant at the base, evolved to chiefly fluvial-lacustrine conditions at the intermediate portion, and to arid conditions again at the top of the unit. The Bauru Group covers an area of about 117.000 km² of the Parana Basin in Sao Paulo State territory. Core samples of this lithostratigraphic unit collected from a drill hole at Pirapozinho (Southwest of the Sao Paulo State) are described and together with well log data brought new information that do not agree with the described model. It was identified in this well the Caiua, Pirapozinho, Santo Anastacio, Aracatuba and Adamantina formations. The study of these core samples clearly showed the dominance of hydrodynamic sedimentary structures and high to medium intensity of bioturbation in whole profile. These characteristics observed in core samples and compared to patterns of geophysical logs testify the dominance of fluvial processes in the Bauru Group deposition at the studied area. These new data suggests that the paleo-environmental evolution of the unit was much more complex, showing strong lateral and vertical changes that diverges from the model more widely accepted in the literature.
