Over time, excessive groundwater usage in urban areas can affect groundwater conditions both in quantity & quality. In some regions, groundwater in the unconfined aquifer has been heavily involved, but for confined aquifers that are deep & tend to be protected, they are not involved too much. The extensive effect, especially groundwater quality, is very significant, especially in coastal areas where seawater intrusion is common & changes in water salinity occur within a specific time range. Regarding these conditions, research was carried out related to changes in spatial & temporal distribution patterns of groundwater quality, exceedingly physical & chemical parameters related to salinity in confined aquifer conditions in coastal areas. By taking a case study in the alluvial plains of Semarang City, this study aims to determine whether there are significant changes in the five years, starting from 2016 to 2020. By using data sourced from groundwater quality tests taken in the reference year, the results gained from the data processing explained that the groundwater quality parameters such as electrical conductivity, total dissolved solids (TDS), acidity (pH), & chloride ions (Cl-) are changing respectively, both spatially & temporally.
