The purpose of the study was to investigate
the ground water pollution in dumpsites. It was an
experimental study. Samples were randomly collected
from dumpsites at recognized location. In March, 2019,
duplicate samples were also collected from each of the
sampling stations. The samples were kept in sterile
containers. The containers were labeled accordingly. At
the occurrence of precipitation, samples containing
rainy weather were collected in a sterile sample bottle.
The samples were carried from the sites to the
laboratory in an ice box which contained packs of
frozen ice. The Wenner array together with Campus
tiger model resistivity was used to measure the six
electrical resistivity imaging lines. The range of the
electrode is between 5 to 35m with a station interval of
5m. The programme RES2DIN was used to invert the
apparent resistivity data in order to get true two
dimensional resistivity distribution in the surface. This
was followed by the plotting and construction of the
topographic map of the area at 5m elevation interval.
The findings of the study indicated that the refuse
dumpsite has a pattern of resistivity variations on the
surface. The resistivity values were carried by solid
wastes, leachate and underlying weathered profile
resulting in ground water pollution. Among others, it
was recommended that law enforcement agents in the
state should ensure that market and domestic wastes
are not dumped indiscriminately.
