Abstract
Results of the electrical and seismic refraction methods
used in the search for groundwater sources in Malumfashi,
Kaduna State, Nigeria have shown that the water bearing
layers are probably sand and clay. A typical geological
section of the area consists of top soils, laterite, clay
and sand and quartz with gravel overlying the basement
complex rocks.
The resistivity values for the water bearing layers
detected vary from 6 m to 47 m and their seismic
velocities range from 1500 m/s to 2,500 m/s. Depth to
probable water table vary from 3.0 m to 12.0 m while the
thickness of the water bearing layers vary from 3.0 m to
29.0 m. The Salinities of the water samples range from
0.06 - 0.26 gm/litre and are found suitable for both domestic
and agricultural purposes. Four areas of probable groundwater
sources have been identified and recommended to the
Kaduna State Water Board for test drillings.
