Groundwater Characteristics and Their Associations with Paleogeomorphological Dynamics in Gantiwarno, Klaten Regency, Central Java Province, Indonesia; A Preliminary

Ensuring the safety of groundwater is essential in ensuring people's health in Gantiwarno, as most rely on groundwater. However, based on the data on disabilities in Gantiwarno, it is very probable that something hidden within its groundwater has caused a high rate of many disability forms. This study analyzes the data on the disability rate in Gantiwarno and its surrounding areas to find the anomaly. Once the rate pattern was figured out, intensive and extensive reference research was performed to find the paleo and current geomorphological characteristics of Gantiwarno. Besides, this study tries to analyze the hydrogeochemistry of the area. The groundwater in Gantiwarno originates from a mixed process called sulfate groundwater. The groundwater in the study location is dominated by Na2SO4 type and unsuitable for health. Contaminants that have caused a high rate of disability in Gantiwarno possibly exist in its groundwater. All of this is possibly caused by the geohydrology, and paleogeomorphological dynamics of Gantiwarno, especially during and after the formation of the Gantiwarno Swamp. This preliminary study has tried to see some possible factors that have caused the situation and invites other researchers to conduct their study in Gantiwarno to investigate further this condition.
