This layer is diagnostic of brackish water which is not suitable for groundwater development. The fourth subsurface layer
consists of fine grain sand with thickness of about 14.7 m to 20 m and resistivity ranges from 230 Ωm to 700 Ωm
consisting of fine sand embedded in water (False aquifer). The fifth layer consists of medium to coarse grain sand
with resistivity values are between 113.0 Ωm to 432.8 Ωm and thickness ranging from 7 m to 15.7 m to a depth of
about 32 m. This is the second aquifer but not too encouraging for prospect for groundwater exploration in the area.
The sixth subsurface layer consists of coarse grain sand and gravelly stones with resistivity values from 430 and
790 Ωm to an undefined thickness. This is the prolific aquifer in Edjekota as it contains appreciable quantity
groundwater.
