    Water is an essential need for earth life including human, animal and plant. Study area located at Toro Jaya Village that has problem with degradation of surface water quality. The purpose of study is to investigate groundwater (aquifer) depth and study the quality of groundwater by groundwater chemistry. Vertical Electrical Sounding (VES) was conducted by using GEOCIST equipment. The result shown resistivity value of aquifer ranging 0,34 – 0,9 Ωm and aquiclude (clay layer) has resistivity value ranging 1,67 – 7 Ωm. Aquifer of study area consist of unconfined aquifer and confined aquifer. The depth of confined aquifer ranging from 3 to 7 m below surface. Quality of groundwater represented by some parameters like pH, TDS, Cl-, SO4 2-, Mn and Fe. All parameters shown that value and concentration is below threshold based on Minister of Health Regulation (PERMENKES) except Fe. Concentration of Fe at study area is 0,71 up to 0,94 ppm but the threshold of Fe concentration is 0,3 ppm. Nevertheless, quality of groundwater at study area can be conclude as good quality.
