The aim of this study was to map the response time of water table depths. For this purpose, time series of groundwater, precipitation and potential evapotranspiration monitoring data were extracted in a representative area of Bauru Aquifer System (BAS), at Médio Paranapanema hydrographical region (UGRHI-17), located in São Paulo state, Brazil. From this data, impulse-response (IR) functions were obtained calibrating the so-called Predefined Impulse Response Function in Continuous Time (PIRFICT) model. Model parameters were interpolated using geostatistical methodology. The results presented themselves as important ancillary tools for decision makers in adopting waste and effluent management practices, water use, remediation plans, and public policies for water resource management.
