Evaluation of Physical and Chemical Parameters of Water Samples Collected from Thenpennaiyar River at Kelavarapalli, Krishnagiri District, South India

Abstract

The present of study is carried out to determine the seasonal variations of physicochemical parameter in the water samples from Thenpennaiyar River, Krishnagiri, South India, which is suitable for human consumption, the study has been carried out during to the one year period (May-2014 to April-2015). The purpose of this study is access to quality of water sources in four different seasons, such as summer (April), pre-monsoon (September), monsoon (December), post-monsoon (February). Water samples are analysed for physicochemical parameters including pH, electrical conductivity, total dissolved solids, free ammonia, turbidity, total hardness, chloride, fluoride, sulphate, phosphate, total alkalinity, Total hardness, Calcium, Magnesium, Nitrite and Nitrate. The Result showed the variations of analyses parameters in the water sample as follows: Turbidity [3.5–8.2] NTU, total dissolved solids[664–840]mg/L, electrical conductivity[948–1194] Mohs/cm, pH [7.47–8.99], total Alkalinity [200–380] mg/L, Total hardness [210–340] mg/L, Calcium [52–72] mg/L, Magnesium [19–38] mg/L, free Ammonia [21.07–58.01], Nitrite [0.24–3.62] mg/L, Nitrate [4–8]mg/L, Chloride [170–200] mg/L, Fluoride [0.20–0.41] mg/L, Sulphate [20–49] mg/L, and Phosphate [1.60–5.26] mg/L. They are determined in research laboratory in TWAD. From the result it is found to the most of the parameters in Thenpennaiyar River is within the maximum permissible limit to WHO and ICMR. The present findings have concluded that the investigation area of Thenpennaiyar River, physicochemical parameters of water samples are not polluted and do not cause any disease and health effects on living organisms. The turbidity of water is more in post-monsoon period compeer to pre-monsoon period. Nitrite is highly summer period compared to the post and pre monsoon period. The total dissolved solid value is highly in post-monsoon period. Phosphate value is high in monsoon period.
