Description
Summary:Jambakan is a village in Bayat District, Klaten Regency, Central Java Province, Indonesia. Brackishwater exists in the aquifers of study area, even though the location is ±30 km apart from the sea. In light of this, scientific discussion on where this water comes from is deemed necessary. The groundwater quality analysis at the local wells, detected brackishwater existence in shallow aquifers at the depths of 5-8 m. The geoelectrical method using the Schlumberger and dipole-dipole electrode configurations screened for any aquifers vertically and horizontally. The results showed that aquifers were distributed discontinuously, for which they were interpreted as fan alluvial deposits in shallow seas or molasses accumulations on the land. The interpretation also revealed that the brackishwater resulted from contacts with minerals in seawater sediments that composed the aquifers in this village.
