The study was showed that the soils of more studied stations were moderately texture (silty loam, clay loam and silty clay loam) while, the second station was just coarse (loamy sand). Also, the study was showed that the plasticity limits (liquid limit, plastic limit and plasticity index) increased with increasing of clay content of soil samples in studied stations. The results showed an in crease of electric conductivity (ECe) and percent of soluble salts by increasing of clay content of studied soils. Also, the results showed an increase of concentrations of SO4-2, Cl-, Na+, Mg+2 in more of studied soils, that’s caused accumulation of sodium, magnesium chlorides and calcium, magnesium sulfates beside concrete bottoms of transportation poles of electric energy, that conduct of degradation and failure of it with time. Also, the study showed that the salinity and depth of ground water caused accumulation of salts at soil surface by capillary and because of depth of ground water was at the critical depth of ground water that increasing the salinity of soil surface in the study stations.
