Abstract

Groundwater is a water resource that is limited in quantity, therefore its utilization must be wise so as not to have a negative impact on the environment. This study aims to detect the potential of drilled wells in meeting the operational needs of the Gedung Kuliah Bersama V (GKB V) UMM. The study was conducted through a well pumping test using static discharge to find the hydraulic parameters of the aquifer and a step drawdown discharge test to find the hydraulic parameters of the well. Data analysis using the Cooper-Jacop, Theis, Chow methods, and data recovery tests produced Transmissivity (T) values ranging from 20.48 - 36.95 m2/d. This value is included in the intermediate aquifer cluster with a production potential of 0.5 - 5.0 l/s. Well tests with step drawdown discharges produced Well Losses Coefficient (C) <0.5 min2/m5 and Development Factor (Fd)<0.1 d/m3, which can be categorized as very good well conditions. Well efficiency of 60% produces a discharge of 3.76 l/s exceeding the planned discharge of 3.00 l/sec indicating that the drilled well is quite reliable in meeting the water needs of GKB V UMM.
