Gapura is a sub-district with a large salt pond in Sumenep Regency, Madura Island,
Indonesia. In this area, many residents’ houses have drilled wells to meet their water needs. One
factor is that Municipal Waterwork (PDAM) does not reach the area due to limited water sources
and difficult accessibility. Residents in the area claimed to have found some groundwater that
tasted brackish. This study aims to apply hydrochemical analysis to identify the possibility of
seawater intrusion in the area. The assessment of seawater intrusion uses the total dissolved
solids (TDS) value and major ion of groundwater samples. In the analysis of thirty samples, two
samples have different values from the samples of freshwater. However, the value of these two
samples is relatively low to be classified as seawater intrusion. It is described on the TDS values
that belong to the class of brackish water, from Simpson ratio values classified as slightly
contaminated, and from the piper diagram plot that is still in the mixing zone in the middle of
the diagram. The presence of brackish water in these samples can be caused by a location close
to salt pond activities.
