<p align="justify">Research area is located in Cigugur District, Pangandaran Regency, West Java Province, and geographically located at UTM coordinates of 210500 - <br /> 216500 mE and 9162000 - 9153500 mS (49S zone). The research area is 51 km2. Based on BMB classification, the research area is divided into four geomorphological units. Those units are Cigugur Cuesta Ridges and Homocline Valleys Unit, Pagerbumi Anticline Valley Unit, Kertajaya Karst Mountains Unit, and Cigugur Alluvial Plain Unit. <br /> Stratigraphically, the research area can be divided into four non-formal lithological units formed in Early Miocene - Holocene epoch. Those units, from oldest to youngest, are Breccia Unit, deposited in inner submarine fan <br /> environment, Limestone Unit, formed in inner neritic environment, Sandstone Unit, deposited unconformably in inner neritic environment, and Alluvial Deposit Unit which is still being deposited along Ci Gugur River until now. Folds and faults in the research area are the product of compressional deformation regime, trending N-S, formed in Plio-Pleistocene epoch. Hydrogeological observation result shows that the aquifer in the research area is a sedimentary rock aquifer system with unconfined aquifer type. Aquifers in the research area are the weathering result of Breccia Unit, Sandstone Unit, Limestone Unit, and Alluvial Deposit Unit. Therefore, the area has potential as recharge area. Its groundwater type is fresh (TDS 44,8 – 353 mg/L) with the dominant flows towards southwest and southeast. Carbonate mineral dissolution <br /> results in higher TDS and pH value in the southern than in the northern parts. Based on TDS and pH value analysis, and referring to Permenkes RI No.492/Menkes/PER/IV/2010, the consumable groundwater is in the northern part.<p align="justify">
