Environmental pollution monitoring studies on thamiraparani river at tirunelveli district, Tamilnadu

The quality of water is of great importance also for human lives as it is commonly consumed and used by households. Runoff water is the carrier of pollutants on their way from the soil surface to the surface water. The fraction of pollutants deposited at the soil surface that ultimately reaches the surface water depends on the amount of runoff and the distribution between the different runoff components.In the present study,water samples were collected from two different locations of Thamiraparani river, Tirunelveli District, India for Physico-chemical analysis.The collected water samples were performed for the analysis of various parameters such as pH, Total Dissolved Solids, Total Alkalinity, Total Hardness, Chloride and Phosphate were analysed for a period of six months from January 2013 to June 2013. Agricultural runoff containing detergents etc, tend to increase pollution. The maximum values of hardness as observed in winter and minimum in summer. Nitrate values were generally high there was luxurious plant growth and results indicate that all the parameters are beyond the limit and unsuitable for human consumption.Due to increased human population, industrialization, use of fertilizers and man made activity, water is highly polluted with different harmful contaminants. The availability of good quality water is an indispensable feature for preventing diseases and improving quality of life. So,it is necessary to know details about different physico-chemical properties. All the physico-chemical analyses revealed that Station II has been more polluted site. The source of pollution is most probably from the cement factory, textile and tannery industries.
