Unscientific dumping of solid waste is a threat to the environment which causes an ecological imbalance with soil, water and air. The present study has been carried out to address the impact of solid waste disposal on seasonal water quality and the determination of the water quality index of the water bodies around the open municipality dump yard in Silchar city, Assam, India. Five sampling and three control points were selected from the different water bodies and analysed for selected physico-chemical parameters, like pH, electrical conductivity, total dissolved solids, free CO2, chemical oxygen demand, dissolved oxygen, total alkalinity, total hardness, calcium, magnesium, chloride, nitrate, phosphate and sulphate and accordingly water quality index has been calculated based on the seasonal data following standard methods. Most of the parameters of the sample sites exceeded the WHO standard limit for drinking water. The water quality index of the control sites was found good in all the seasons in contrast to the sample sites. Therefore, to protect the environment, it is very important to adopt proper scientific practices for waste disposal.
