Urbanization and Industrialization Impact on Surface Water in Coimbatore-Sulur Subwatershed

Abstract

Industrial pollution and urbanization is a major threat to the water environment.The advent of urbanization and industrialization for economic growth has adversely affected the biological diversity. Lake water quality deterioration has been evident in the lakes surrounding the city of Coimbatore. The growth of industries in the city has led to the increase of population day by day in the city The present study is mainly aimed at studying the nature and impact of water pollution in the sub basins of noyyal river basin in coimbatore-sulur subwatershed which has a major impact on the Environment, Health and Socio-Economic status. To understand the magnitude of the impact, water samples were collected in and around the Coimbatore city namely Sulur lake, Singanallur lake, Valankulam, Ukkadam lake and Noyyal river stream which falls in Coimbatore-Sulur subwatershed and analyzed for physical, chemical and bacterial characteristics. The study showed that the chemical characteristics were relatively higher (TDS-957mg/l), (Cl-439.58mg/l), (NO3 -56.28mg/l) than the Bureau of Indian Standard acceptable limits and the presence of Escherichia Coli(60cfu/100ml) and Total Coliform(400cfu/100ml) are menacing in all the water samples leading to major health impact in human beings and also the quality of water is deteriorated.
