Monitoring of water and sediments of Ulhas River north-east of Bombay

K.C. Sahu, S. Mukherjee


The Ulhas River, Bombay, Maharashtra, India descends from the Western Ghat range and from Kalyan onward develops typical estuarine environments before meeting the Arabian Sea at Vasai and Thana Creeks. Discharge of industrial effluents from the Kalyan-Ambernath-Ulhasnagar industrial belt and sewage disposal from the suburban settlements has considerably polluted a section of the Ulhas River. Water and sediments of the river have been monitored at several points to recognize the nature and extent of pollution. Based on the field data and laboratory experiments on the soils and sediments of the region, the containment capacity of the soil matrix has been evaluated for the heavy metal pollutant present in the contaminated water. A suggestion has been made for decontamination of the polluted Ulhas river water by land application for irrigational use with rigorous monitoring of all the compartments of the ecosystem
