Assessment of Hydrochemical Facies on Groundwater Quality in Daenaa Village and its Surroundings, West Limboto District

The study is required to evaluate the groundwater condition, such as finding relationship with lithology, determining facies of groundwater, and providing an overview present conditions, genetics, quality. This aims explain between lithology chemistry, quality, determination chemical determine genetic type groundwater. uses field survey methods random sampling techniques, measurements physical properties, trilinear piper diagrams, laboratory analysis in form rock geochemical (XRF) at PSDMBP Laboratory PT Global Quality Analytical Laboratory. results show that area consists clastic limestone, sandstone, breccia, dacite. Lithology primarily plays essential role ion enrichment Determination quality based on Permenkes, Permen ESDM, ISDW, which obtained eleven well points good category, five poor four other categorized Based diagram, there one (not varied), namely Ca-Cl facies. presence interpreted a seawater intrusion phase.
