Groundwater in Palapye, Botswana was studied using a model to estimate recharge rates and understand the aquifer's behavior. Environmental tracers like chlorofluorocarbons were used to confirm the model's accuracy. The aquifer is mainly made up of fractured sandstones and its water potential varies depending on connections to large fractures. The recharge comes mainly from precipitation, with little evaporation before reaching the water table. Recharge rates were estimated to be between 2% to 10% of the mean annual rainfall, in line with previous estimates.
