Waters have some function for human life. So, the necessary of water is very much. Clean water specially. The clean water is more function as much as the peoples growing. The necessaries just from the surface but from the groun water. Groundwater can be faound at permeable geological structure, as known with aquifer. The reseach of aquifer depth with geoelctrical method is better.

Because this method are popular and give information of reservoir rock resistivity. Pakisaji District is the area wich have difficult geological formation with little groundwater debit. The water pump are in the street side. Just some dots.the peoples knowledge about groundwater depth are minimally. Because of that very important to do some reseach in this district and may can solve the water problems and can know the case that caused in Pakisaji.

In this reseach use the survey method with geoelectrical equipment.with  2 villages as samples. Kendalpayak and Karangpandan. This method use 5 sounding dots. The data from samples are analyzed with IP2win sofware. This results are rock resistivity. Next step is interpretation from this resistivity. From tis step we can know the rock arrangement. The last step is making the map with Surfer 9.0. 

The aquifer from analisist can be found in dot 1 at 14,885 m and 47,9 m. In dot 2 at 9,972 m and 45 m. In dot 3 at  4,58 m and 33,7 meter. In dot 4 at 1,87 m. And the last dot in dot 5 at 0.838 m. The aquifer at dot 1 has highest debit with q = 7,08 m/s, and at dot 4 with q = 1,36 m/s. 

According this result, we can know some conclutions. (1) the Northern Pakisaji has more potential aquifer than Southern Pakisaji, with 6 aquifer structure from 3 dot. The aquifer thickness of Northern Pakisaji is bigger than Sothern Pakisaji. So do the permeability and aquifer debit. (2) the accuration level from this method and equipment is good with error average 1,78%.
