Item Unscientific methods of disposal of solid waste as landfills on low lying area cause serious environmental geotechnical problems. The leachate generated from the decomposition of solid waste causes the pollution of soil layers. In this study an attempt has been made to investigate the effect of leachate on soil chemical properties by laboratory tests. The tests included the pH, Electrical conductivity, Hardness, Chlorides, Sulphates, Nitrates, Sodium, Potassium, Ammonia, Nitrogen and Phosphate contents of lateritic soil. The results of this study are presented in this paper.

The key characteristics evaluated included Atterberg limits, compaction characteristics, hydraulic conductivity and chemical characteristics of selected soils. The sea at this coast receives effluent from different points and hence the characteristics change with time and locality. Therefore, to maintain uniform composition, 0.5 N sodium chloride solution (NaCl) was prepared in the laboratory and batch tests were used to determine the immediate effect on soils. Soil specimens were prepared by mixing the soils with 0.5 N NaCl in the increments of 0, 5, 10 and 20% by weight to vary the degree of contamination. Experimental results of soils mixed with 0.5 N NaCl showed that the maximum dry density increases and the optimum moisture content (OMC) decreases with increasing sodium chloride concentration. The study also revealed that the hydraulic conductivity of the soils tested increases with increase in sodium chloride concentration. The Atterberg limits of contaminated specimens show a remarkable change when compared with uncontaminated specimens. © 2010 Springer Science+Business Media B.V.
