Despite the abundance of surface water resources in tropical countries, creeping pollution problems created by rapid industrialization call for the development of new uncontaminated water resources. Such can be found in the Parana basin, South America, where a huge untapped sandstone aquifer extending over about 1,000,000 km2 (mostly protected by confinement) might easily replace the deteriorating surface water currently in use. This aquifer (Botucatu) was studied extensively in the Sao Paulo state, Brazil, and in Uruguay. In the present paper a geohydrological evaluation using unconventional methods is discussed. |
