Hydrochemistry types of the Bauru Aquifer System in the State of São Paulo
Groundwater is used for public supply in 55% of Brazilian municipalities. In the state of São Paulo approximately 72% of the cities, with an estimated population of 5.5 million inhabitants, are fully or partially supplied by groundwater, being Bauru Aquifer System the most widely used aquifer.
