Resumo
Among the geothermal energy direct-uses categories, bathing and tourism applications
(balneotherapy, health, well-being, recreation, and swimming pool) correspond to almost all
installed capacity in Brazil; where the best quality resources with the highest thermal power
range occur in the Guarani Aquifer System (GAS). In a comprehensive international project
on the use and protection of this transboundary aquifer, it is recommended to evaluate the
potential uses and characteristics of its geothermal resources. Through the hot/mineral
springs are developed resorts, water parks, SPAs, bath centers, and wellness destinations,
with recognized economic benefits and inducers of sustainability. Thus, this work compiles
physicochemical data (temperature, TDS, pH, SO4
-2, HCO3
-
, Cl-
, F-
, Na+, Ca+2, Mg+2, Si, B-3,
Fe, Li+, Mn+2, Zn+2) from 85 hydrothermal wellsprings located in GAS (Brazil, Argentina,
Uruguay and Paraguay), where tourism activities related to balneology are observed. The
values obtained are compared with minimum levels of beneficial bioactivities, literature
referenced to balneotherapy. The results indicate potential biologically active components
(BAC) present in most of the sites, fountains and thermal/mineral waters evaluated here,
through baths to experiences of SPA, relaxation, skincare, well-being or thermal medicine,
according to the forms and the continuity of the expositions. It is expected to contribute to
regional tourism development and marketing, as well as the promotion of related biomedical
research.
