Due to increasing industrialization and urbanization, waste water pollution is increasing day by day. The disposal of waste water from Sugar Industry in Yamunanagar is seriously changing the properties of agricultural soil. Huge amount of water is consumed in the sugar industry, on an average 20-30 tons of water is needed to process 1 ton of sugar. Sugar industry is one of the most polluted industries in India. India is the second largest producer of sugar in the world. Waste water of Sugar Industry is usually all active in nature. It also contains high contents of bicarbonates, carbonates, phosphates, nitrates and heavy metals ions. It also has high value of BOD, COD, Suspended solids, dissolved solids and total solids. It was observed in the study areas that the effluent of sugar mill affects the physico-chemical properties of the soil. Irrigation with sugar mill effluent has lead to increase the soil alkalinity pH, electrical conductance, organic carbon and available nutrients. The concentration of N, P, K and Na also increased in the soil after irrigation with effluent of Sugar Mill as compare to water from the well. Soil samples have been collected from the affected areas as well as from the sites where irrigation is done with well water. All the contaminants found in the soil samples of various sites where irrigation is done with sugar mill effluent were not to be found in permissible limit. Concentration of heavy metals was found higher in surface layer than the subsurface layer of soils. High concentration of heavy metals become phytotoxic and affects plant development and its growth. This study observed that the soils were contaminated badly due to the discharge of sugar mill effluent in these areas.

BOD, COD, pH, phosphates, carbonates, heavy metals, conductance.
