ABSTRACT

The city of Semarang, especially the Genuk area and its surroundings, is currently categorized as a critical zone for groundwater utilization because of the large groundwater abstraction discharge and poor groundwater quality. To fulfill the need for clean water, both for domestic and industrial purposes, groundwater is used to a depth of 150 masl, but it is still not fully fulfilled, especially for large-scale industries. Therefore, it is necessary to investigate the existence or potential of aquifers that are below a depth of more than 150 masl. The method used was a VES geoelectric survey with a Schlumberger configuration, drilling test wells, well electrical logging resistivity and Self Potential (SP) methods as well as porosity and permeability tests of aquifer samples from a depth of more than 150 mdpt.The results of the geoelectrical interpretation show the presence of an aquifer carrying layer at a depth of 135 – 220 meters. Meanwhile, from the measurement well electrical logging confined aquifer carrier layer at a depth of 160 - 176 meters and 188 - 210 meters. The characteristics of the aquifer at a depth of 160 – 176 meters have a porosity value of 2.9 – 8.22% and a hydraulic conductivity value of 0.017 – 0.036 m/day. The characteristics of the aquifer at a depth of 188 – 210 meters have a porosity value of 11.6 – 19.899% and a hydraulic conductivity value of 0.09 – 0.23 m/day. The results of this investigation generally indicate that there was a potential for depressed aquifers in this area at depths of more than 150 masl.
