Abstract: Surface self-potential SP geophysical method conducted in Seikanian suburban area situated in north of Kirkuk city about 5 km which is suffer from deficiency of water supply. To acquire SP data two survey lines of gradient layout achieved , one in northern part near the foothill another perpendicular to the former, addition 22 grid points of SP measurements taken spread over the studied area. Water Pumping test carried out in a well with SP reading monitoring the water table drawdown operation. The aim was to delineate underground water accumulation and sensitivity of self-potential signal to water hydraulic head in the well. The acquired data interpreted by profiling curves and SP contour maps using Surfer 8 Software. The results showed there is streaming electric potential condition in the subsurface of the studied area indicates groundwater existence and the pumping test procedures with accordance by monitoring SP device proved that SP readings is sensitive to hydraulic head which is a good tool to estimate some hydrologic properties namely water transmissivity and conductivity of the aquifer . The water table depth is about 7 m in the study area.
