Aquifer Susceptibility to Groundwater Pumping in Kediri City, East Java Province, Indonesia

The development of Kediri City in various sectors, such as industry, agriculture, and population growth, also increases water. The utilization of groundwater is still a major mainstay in this area. The utilization of groundwater includes the construction of production wells for irrigation and raw water. The aquifer susceptibility should be considered during groundwater exploitation to minimize a negative impact on the environment. This research aims to analyze the susceptibility of the aquifer to pumping in Kediri City, which is helpful for planning and making decisions in the management of groundwater resources. The determination of aquifer susceptibility is based on aquifer response characteristics, aquifer storage characteristics, allowable subsidence of groundwater level, and depth to the groundwater table. Based on those parameters, it can be concluded that the aquifer susceptibility on groundwater utilization in Kediri City is at moderate and high levels. Areas with moderate aquifer susceptibility are located on the west side of Kediri City, and high aquifer susceptibility is in the middle to the eastern side of Kediri City.
