Description
Summary:Climate change has a negative impact on the reduction of groundwater resource potential in the Gunungsewu Karst Area, in terms of quantity, quality and continuity. This impact is felt by the people of Pucung Village who use water found in underground rivers and springs to meet their daily domestic water needs. The potential of water resources in the area is very vulnerable to a decrease in quality and quantity related to changes in the carrying capacity and capacity of the karst area as a result of climate change. This study aims to assess the groundwater vulnerability zone and the condition of the water catchment area in the karts area of Pucung Village, Eromoko District, Wonogiri Regency, Indonesia.The research method used is the EPIK method which is applied to the Geographical Information System (GIS). Research variables include (a) Epikarst; (b) Protective Cover; (c) infiltration conditions, and (d) karst network. The four variables obtained from the interpretation of remote sensing images, topographical maps, geological maps and field surveys were analyzed using scoring techniques. The results showed (1) 875.15 hectare or 88% of the area in Pucung Village is in a zone that is very vulnerable and susceptible to contamination of Groundwater; (2) agricultural activities in the water catchment area have the potential to contaminate of groundwater in the study area.
