ABSTRACT

Water is an essential natural resource for improving economic activities, especially in urban areas which have domestic and industrial activities. The massive freshwater resource on earth is groundwater. In contrast, the volume of groundwater resources is minimal compared to the whole water volume in the world. Information on groundwater recharge is essential for optimum utilization. Therefore, this study aimed to estimate groundwater recharge using the Chloride Mass Balance (CMB) method in old and new residential areas in Yogyakarta City, Indonesia. This study was carried out during a period of the dry season and the wet season starting from September 2021 to February 2022. Collected data in this research were daily rainfall of 6 months of observation, nine groundwater samples, and three rainwater samples of each study area. The chemical content of groundwater and rainwater samples was analyzed using ion chromatography to obtain each sample's Cl- concentration. The analysis showed that the average yearly rainfall in both study areas is 2972.39 mm/year. The average Cl^- concentration of groundwater in old and new residential areas was 21.06 mg/L and 22.65 mg/L. The average Cl^- concentration of rainwater in old and new residential areas was 0.90 mg/L and 0.83 mg/L. Using the CMB method equation, the average groundwater recharge in old and new residential areas was 126 mm/year and 109 mm/year. These values were far below the result of groundwater recharge estimation reported by previous studies.
