Water is the source of life for all living things on Earth. Indonesian people make groundwater the main source of water, including the people in Semarang City. The city of Semarang, which is the capital city of Central Java province, with the development of industry, trade and tourism growing rapidly, has forced groundwater exploitation on a large scale. As a result, disasters such as drought, the phenomenon of seawater intrusion and groundwater contamination have started to occur in the city of Semarang, especially in the alluvial plains area. This study aims to determine the level of groundwater contamination in the study area. In this study, 30 groundwater samples were taken to test the chemical content of groundwater. The methods used were the geospatial analysis and the Pollution Groundwater Index (PGI). The geospatial in Geographic Information System/GIS method aims to determine the distribution of groundwater quality in the study area. The PIG method aims to determine the level of groundwater contamination. PGI results show that there is 1 sample belonging to high pollution and 1 other sample belonging to groundwater with very high pollution. Geospatially, it shows that the distribution of groundwater contamination is in the western and central parts of the study area. This is also supported by geospatial analysis for the physicochemical conditions of groundwater which includes parameters of pH, EC, TDS and Hardness. From this research, it is known that groundwater in Semarang City is starting to experience pollution. So there is a need for efforts to restore groundwater conditions and start reducing the use of groundwater by utilizing surface water.Introduction
