Geotechnical properties of soil get modified on contamination with industrial wastes and garbage. Extent of modification of geotechnical properties of soil depends on chemical composition of the contaminant and soil and amount of contaminant present in soil. Depending on the nature of contaminant, positive or negative effects of contaminant on the engineering properties of soils are possible. Detrimental effect of contaminated soil can cause foundation failures resulting in considerable damage to the structure built on it. On addition of some industrial waste, such as textile effluent, engineering properties of soil get improved. In this review, effect of petroleum products, acids, alkalis, salts and industrial effluents on engineering properties of soil is being discussed.
