Geophysics survey have been done at Ngaglik, Sambi, Boyolali in determining the depth and spreading of salt water aquifer. The equipment used in this survey is OYO McOHM-EL model 2119 C. This research used resistivity method with the Wenner configuration for mapping and dipole-dipole configuration for sounding. The mapping data was processed using a software surfer and the sounding data was processed using a software RES2DINV. The result of this research showed that the resistivity value of salt water aquifer is in the range of 0.1 – 1.0 Ωm and the depth is less than 10 m. It spreads about 60 m to the north from the source of salt water. This aquifer is predicted as a mixture with clay and surrounded by sand stone and clay stone.
