Águas de São Pedro
For four years, the Institute for Technological Research (IPT) of the University of São Paulo conducted a series of studies of those waters. Generally, water from great depths has a high concentration of substances that may be harmful to human beings, and its pH may not be suitable for bathing. In 1940 the results were published in Bulletin 26 of the IPT. The waters were deemed good for bathing, and their medicinal properties were studied by Professor João de Aguiar Pupo, Dean of the Faculty of Medicine of São Paulo.
