Physico-Chemical Analysis of Water Quality Parameters in Aruvikkara Reservoir, Thiruvananthapuram District

The present attempt is to analyse the Physico -chemical Parameters of Aruvikkara water Reservoir in Thiruvananthapuram District. Monthly observations were carried out from 1^st June 2011 to 31^st May 2012. Physical and Chemical Parameters viz. Water Temperature, pH, Total Hardness, Alkalinity, Nitrates, Silicates, Phosphates, Dissolved Oxygen, Chemical Oxygen Demand were analyzed. Our study revealed that all Parameters were within the permissible limits as suggested by WHO and CPCB. The results indicate that the reservoir is Non-polluted and can be used for Domestic and Irrigation purposes.
