The paper presents the results of factor analysis multi-electrode geoelectric data measured in area Surány aquifer. 9-variable dataset on first profile was examined by using 2, 3, 4 and 5 factors. calculations show that Factor 1 carries effects IP (Induced Polarization), while 2 shows effect apparent resistivity (Rho) with greatest weight. In weight current (In) is largest. Based all this, it c...
