Abstract
Traditionally, spring water is one type of water resource that is important for meeting clean water and irrigation needs. The Dieng Plateau in Central Java province is a national tourism strategic area (KSPN). Being located in 2 groundwater basins, namely CAT Wonosobo and Karangkobar, the Dieng Plateau has problems in fulfilling the clean water needs. With the rise of tourism in Dieng, clean water needs must be covered in terms of quality and quantity. Many cold springs in the Dieng area have not been maximally utilized. Therefore, it is important to conduct a spring inventory to supply the community^s need for clean water in the future, both in quantity and quality. This study collected data on springs^ presence and measurements of groundwater^s physic-chemical properties and spring discharge. From the mapping results, 16 (sixteen) springs occurred in the study area. Based on the measured discharge value (l/s), the total spring discharge was 251 l/s, with a maximum discharge value of 133.2 l/s in the CAT Karangkobar area. The Dieng Plateau springs have complied with the drinking water standards based on applicable references and regulations regarding physic-chemical parameters. This is proven by the average pH value of 7.07, the average TDS of 206.1 mg/L, the average EC of 412.1 μ-S/cm, and the average temperature of 18.2 degC. The springs in the Dieng area are classified as cold/normal springs based on their groundwater temperature and have potential as a raw water source.
