The presence of groundwater is strongly related to its geological and geohydrological conditions. It is, however, important to study the groundwater potential in an area before it is utilized to provide clean water. Werner-Schlumberger's method was used to analyze the groundwater potential while hydraulic properties such as soil porosity and hydraulic conductivity were used to determine the quality and ability of the soil to allow water's movement in the aquifer. The results show that the aquifer in the Sekara and Kemuning Muda is at a depth of more than 6 meters below the ground level with moderate groundwater potential. It is also found that the aquifer at depths of over 60 m have high groundwater potential. Moreover, soil porosity in Kemuning is found to be average while the ability to conduct water was moderate. This makes it possible for some surface water to seep into the soil while the remaining flows to the rivers and ditches.

There are rising interests in the utility of groundwater in various aspects, which is capable of triggering problematic issues. The excessive exploitation for anthropologic uses, without regards to aquifer capacity, will decreases the water table as well as capacity of groundwater in the aquifer. This research was aimed to provide aquifer model of underground water by consideration of various environmental factors, with the propensity of being modeled, in an attempt to predict groundwater conditions in subsequent years. The purpose of this research was to forecast water requirements, availability, as well as three-dimensional model of groundwater depth in Kemuning, Indragiri Hilir Regency-Indonesia between 2015 and 2022. Furthermore, various environmental factors, from aquifer proiles to anthropologic demand, are taken into account in the evaluated model, including water requirements, encompassing recharge and aquifer parameters, which consists of storativity and transmissivity. From anthropologic side are domestic requirements, trade, public facilities, agriculture, and livestock. The results show that groundwater availability in Kemuning is to be safe condition, and average diference is 1.06×108 m3/yr. The coeicient of storativity and transmissivity are 16.514 m2/day and 9897.26 m2/day, respectively, while the average depth was recorded as 2.8965 m to 10.4927 m.
