N. Manonmani

In order to understand the utility, various physico-chemical characteristics of the water of Narikulam tank in Kanyakumari District of India were studied for a period of five months starting from January to June, 2009. Ecological parameters like temperature, pH, electrical conductivity, chlorinity, salinity, dissolved oxygen content, biochemical oxygen demand and total hardness were analysed and compared with standard permissible limits to assess the best-designated use of this water for various purposes. Coliform study was also made. The results indicate that this water can very well be used for agricultural purposes, washing, bathing, etc. and proper purification is needed, if used for drinking purposes.
