Abstract

Groundwater resources are vital for residents in Muntilan Sub-District and its surrounding area in Central Java. The residents use groundwater for daily consumption by developing dug wells. Therefore, groundwater sources from contamination should be protected to guarantee sustainable groundwater use in this area. Groundwater vulnerability maps can be used as basic information to prevent groundwater contamination, land-use planning, and groundwater resources management. Therefore, this study aims to develop the groundwater vulnerability map in the Muntilan, Salam, Ngluwar Sub-Districts, Magelang Regency, Central Java. The vulnerability assessment used the DRASTIC method. The method has used the sum of the weighting of various parameters, including topography, net recharge, groundwater depth, the impact of the vadose zone, soil media, hydraulic conductivity of the aquifer, and aquifer media. The analysis results described that the DRASTIC Index (DI) value ranges from low to high levels, low levels, and the moderate level of vulnerability covers Muntilan sub-district and salam sub-district, while high levels of vulnerability are located in Muntilan, Ngluwar, and Salam Sub-Districts. Therefore, this vulnerability can be used for regional spatial planning and groundwater protection in the district.
