“…The first major aspect is related to the unit adopted for the waters classification based on radioactivity. Mache reported in 1904 and 1905 the presence of radioactivity in waters occurring in Austria and Jáchymov, today Czech Republic [17][18][19], discovery that allowed the installation of spas in some sites. Mache also introduced one unit for expressing the radon activity, which was later named Mache Unit (MU), commonly used in Austrian and German literature.…”

This investigation was carried out within São Paulo State, Brazil, and involved the sampling of well-known mineral bottled waters for performing a comparative hydrochemical study and of a spring occurring at Corumbataí city, in order to evaluate its suitability for bottling. Several methods were utilized for acquiring the hydrochemical data like the methyl orange end-point titration, potentiometry, ion selective electrode, colorimetry, flame photometry and inductively-coupled plasma spectrometry. The results obtained for the analyzed samples were compared with the guideline values established by the National Commission of Rules and Standards for Food of the Brazilian Health Ministry published in 1976. The Brazilian Code for Mineral Waters that was established by Register 7841 published on 8 August 1945 was also taken into account for verifying if the spring waters are mineralized. The hydrochemical data allowed identify some constituents impoverishing the water quality, thus, implying on its nonutilization for commercial purposes (bottling). In one specific case, the spring water only can become appropriate for human consumption after previous chemical treatment.
