Abstract

The Tubarão Aquifer System is the main hydrogeological unit of the Capivari Municipality, State of São Paulo. Approximately 63,7 % of the total public water supply is drawn from it. This system is assumed to be extremely heterogeneous and discontinuous with variable discharge. It has been intensively exploited, as is evidenced by the potentiometric surface drawdown due to the increase of wells drilled in urban areas in recent decades. This scenario motivated the diagnosis of the hydrogeological potential for the Capivari Municipality, which defined areas of greatest productivity and exploitation. This study resulted in the proposal and delimitation of restricted areas of the aquifer, which will be of help for the establishment of municipal laws regarding groundwater exploitation and protection.
