Abstract
Groundwater survey has carried out at Samigaluh and its surrounding area, West Progo. This area is included in West Progo Dome and topographic map of Sendangagung. This research has been done by hydrogeological survey, equipped with groundwater sampling of four samples for physical/chemical testing at laboratory. Field data collecting includes physical properties (color, taste, odor, turbidity) and chemical properties (pH, TDS) of groundwater as well as local geological condition. Laboratory data is similar to field data plus ion contents. Data analysis includes hydrochemistry of groundwater based on all data. Results of research show that groundwater in research area is usually colorless, no taste, no odor and clear. Groundwater develops in most variable types, such as Ca-HCO3, Ca, Na-HCO3, Ca,Na,Mg-HCO3 and Ca,Mg-SO4. Groundwater types vary in some Piper class. The hydrochemical process is dominated by ion exchange, besides simple dissolution or mixing. The dominant groundwater facies are bicarbonate, due to the influence of siliciclastic rocks that interact with groundwater through the dissolution process. The number of elements Ca2+, Na+, and silica in the groundwater is influenced by the weathering of silicate minerals such as feldspar, plagioclase and clay minerals which derived from weathering minerals.
