## Abstract
Abstract The purpose of this study was to determine the aquifer parameters and the condition of groundwater in the study location, namely the continuity coefficient (Transmissivity, T), water retention (Storativity, S) and permeability coefficient (Hydraulic Conductivity, K). This aquifer parameter is very necessary, especially in the project to be excavated for basement construction, where the high groundwater is one of the problems that must be overcome when the excavation of the soil. This pumping test was carried out by making 10 investigation well points, namely 1 point of the pump well (TW) and 9 points of observation well (OW1-OW9). Thus the pump well (TW) is installed to a depth of 20 m, the end is 2 meters into the hard consistency clay layer. While 9 points of observation well (OW1 - OW9) were installed to a depth of 15 m, so that all the pipes were in a layer of the fine sand relative density of moderate just above the very stiff consistency clay layer. Based on calculations with the Theis method obtained: a) The cross-section A-A has a value of Transmissivity (T) ranging between 124.27 - 966.58 m2/day, Hydraulic Conductivity (K) ranges between 0.012 - 0.094 cm/s, Storativity (S) ranges between 0.084 - 0.472. b) The cross-section B-B has a value of Transmissivity (T) ranging between 230.14 - 621.37 m2/day, Hydraulic Conductivity (K) ranges between 0.022 - 0.060 cm/s, Storativity (S) ranges between 0.125 - 0.416.
