Identification of the groundwater basin system is needed to get qualitative and quantitative data like as surface and subsurface geological condition, type of aquifer, number of aquifer, aquifer medium, relation between aquifer. And also the datas of aquifer hydraulic charateristic, hydraulic conductivity, transsmissivity and specific capacity. These condition can get to predict the groundwater potential and the amount of groundwater can be taking in order to groundwater balance in that area.<p>The study is taken in Umbulan groundwater basin in the town of Pasuruan and Pasuruan residence, East Java. Umbulan groundwater basin is a part of the Pasuruan-Ponorogo groundwater basin, and having area 1012, 62 km2. Geological condition mainly is volcanic rock result volcanic eruption consist of Tuf Rabano and Upper Quarter Volcanic Rock. The lito logy is sandy tuff, breccia tuff, breccia, sandy breccia, volcanic breccia, pumice tuff and lava. <br />
