The method of high-density resistivity consists in passing direct current into strata to measure the
electrical resistivity and to identify the interface between different materials and the measured result is
called resistivity profile. The method is used to locate groundwater resources as well as investigate
building and dam foundations, karst collapse and mine goaf [1-4]. This method is, more recently, being
applied to investigate groundwater pollution [5-8]. There are several electrode arrangements for the
method such as Wenner Array (Fig. 1), Schlumberger Array, Pole-Pole Array and Dipole-Dipole Array
which are applied during the research. Study results show that the four arrangements can be used to
ascertain pollution plume and Schlumberger Array do not express as good as the other three arrays.
