Abstract:
The condition of an inundated and non inundated area is influenced by geology of a
particular area. This will affect the condition of the aquifer layer. This research aims
to identify the groundwater aquifer layers and quality. Measurements was conducted
in Delima Village, Binawidya Distric using the Wenner configuration geoelectric
method on two tracks with different geological conditions, which are inundated and
not inundated with a measurement distance from the starting point of approximately
150 meters and 100 meters. The analyzed parameters for groundwater quality tests
are pH, Turbidity, TDS, COD and Total Coliform. Based on the result of data
processing for the first track the aquifer layer is at a depth of 9,26-15,9 meters and a
thickness of 6,6 meters with a resistivity value of 22,8-267 Ωm. The second aquifer
track is found at a depth of 7,46-9,56 meters and a thickness of 2,1 meters with a
resistivity value of 49,3-299 Ωm. Based on the result of soil Physics analysis, the
permeability show that the Litology of the subsurface layers is dominated by
sandstone layers with the value of 6,01-6,04 cm/hour. All analyzed water samples is
still meet the requirements for clean water quality except water quality of total
coliform bacterial parameters from the sample track 2 which exceeds clean water
quality standards.
