Abstract

In the present study an attempt has been made on physico-chemical characteristics of urban ponds located
in Thiruvananthapuram district of Kerala. The study was carried out for a period of one year i.e. January
2012 to December 2012. Seasonal details have been collected and analysed with single factor ANOVA.
Different parameters were like pH, Temperature, Turbidity, Electical Conductivity(EC),Total Dissolved
Solids(TDS),Total Alkalinity(TA),Chloride, Total Hardness(TH),Dissolved Oxygen(DO),Biological Oxygen
Demand(BOD),Nitrate- Nitrogen. The result of the present study indicated that the water quality of all the
ponds lies below the permissible limit. (WHO)
