The new airport development plan in Kulon Progo district requires detailed information about carrying capacity of the environment. One of important parameters of carrying capacity is hydrogeology condition. Therefore, it is important to conduct hydrogeology study in this location. The aim of this research is to know groundwater quantity as well as quality. The method uses in this research comprise geological mapping, hydrogeological mapping, groundwater sample analysis and geophysical analysis. It shows that groundwater flow relatively to the south with groundwater depth is 0.2-5.7 m from local datum. Groundwater quality is still good with electric conductivity (EC) value 150-1190 µs/cm, total dissolved solidified (TDS) value 80-540 mg/l and pH 6.5-7.5. Based on the groundwater chemical composition can be divided into 4 types, that is (a) Na++K+ - HCO3, (b) Ca2+ - Na++K+ - HCO3 (c) Na++K+ - HCO3- - Cl- (d) Na++K+ - Mg2+ - SO42- - HCO3-. According to dimension and characteristic of aquifer the volume of groundwater is 2,895,903 m3. Generally, this location has a good groundwater quality and have not been exposed to groundwater pollution
