Groundwater sensitivity studies are widely used to protect aquifers in basins from pollution elements and to take necessary precautions. In this study, the SINTACS model was used in conjunction with GIS and AHP to determine groundwater sensitivity. The SINTACS model is generally preferred in karstic lithologies. The Burdur Cine Basin (BCB) is located in the karstic area defined as the Taurus Limestone Belt in southwestern Turkey. In the basin where intensive agricultural activities are carried out, there is a university campus and numerous villages. The groundwater in the basin is used both for drinking water in Burdur province and for agricultural activities. In determining the sensitivity of groundwater; the parameters of water depth (S), infiltration (I), unsaturated zone (N), soil (T), hydrogeological features (C), and topographic surface (S) were used. These model parameters were weighted using normal and karstic SINTACS scenarios based on the characteristics of the basin. In the parameter weighting process with AHP, the geological, hydrogeological, meteorological, and land use characteristics of the region, particularly the karstic structure, were taken into account. The SINTACS index was found to be in the range of 26-222, while the modified SINTACS index was in the range of 63-269. The modified SINTACS method has provided higher index values due to the addition of two parameters. According to the modified SINTACS method, it has been determined that 44.36% of the basin has very high, 22.08% high, 13.02% moderate, and 10.17% extremely high sensitivity. The areas with very high and high sensitivity include areas where the slope is low and soil over the aquifer is permeable. This situation indicates that the groundwater aquifer in the basin is highly sensitive to pollution.
