Ground Water, Pollution, SINTACS Method, DRASTIC Method, VulnerabilityAbstract
Most residents of Sumobito District still use groundwater as their raw water source through dug wells. Groundwater in this area is potentially vulnerable to pollution. This can happen because of the increasing number of industrial and household waste, as well as the use of pesticides on rice fields, which triggers the emergence of potential sources of pollution for ground water. This research aims to identify the location distribution of groundwater vulnerability levels. Identification was carried out at 23 dug well points that had been determined for 5 months. The methods used in this research are the SINTACS method and the DRASTIC method with 7 hydrogeological parameters each. The results of this research are dominated by rather high vulnerability which tends to be in the western and southern parts of the research location with an area of 17.43 km2 to 39.66 km2 for the SINTACS method. Meanwhile, the DRASTIC method is dominated by moderate vulnerability which tends to be in the eastern and southern parts of the research location with an area of 46.79 km2 to 47.20 km2. Sustainable groundwater protection planning with a land conservation perspective is the right step to prevent contamination of groundwater from pollutant sources.
