Chandrakala2. 1,2Assistant Professor, Department of Chemistry, Sir MVIT, Bangalore, Karnataka, India. Abstract─The present study was carried out to analyze the parameters of the water of River Kaveri before the onset of quality of water of Kaveririver before the commencement of the Monsoon that could help in maintaining the quality of Rains. Kaveri is considered as lifeline of Southern India and river water for the users.The study aimed at the carry the same sentiments and importance as the holy river determination of various physico-chemical parameters such Ganga.It originates from the hills of Talakaveri in Coorga in as temperature, pH, Conductivity,TDS, Turbidity, Hardness, Karnataka and flows through the two Indian states of 2+ 2+ − Karnataka and Tamilnadu before merging with the Bay of Alkalinity, Concentration of Ca ,Mg and Cl ions etc and Bengal. Both states share the water for farming and irrigation compares these parameters with Indian and International of their lands. Krishnarajasagara is a massive dam built across standards to ensure the quality of Kaveriwaters. Kaveri near Mysore. Many historic, religious and tourist places have developed on the banks of the river. Thousands of II. MATERIALS AND METHODS tourist and pilgrims visit these places every year. This made the authors curious to study the quality of the water of river Samples were collected from two different places as per Kaveri. To begin with this the water samples from the standard procedures. Sample-1(S1) from near the Mysore riverwere collected at two different sites. Sample S-1was city and Sample-2 (S ) from near theCoorg city .The various collected near the Coorg city and sample S-2 was collected 2 from a tourist spotnear the Mysore city. The various Physico- Physical and Chemical parameters were studied and the Chemical parameters studied were temperature,pH, resultsobtained were compared with theWHO and ISI Conductivity, TDS, Turbidity, Hardness, Alkalinity, standards. Chemicals used for analysis were of AR grade. Concentration of Ca2+,Mg2+and Cl− ions etc. All these For thepreparation of the reagents glass distilled water was parameters were then compared with the WHO and ISI used. The glassware’s used were made up of Borosil. standardsto draw the final conclusion on the quality of water Electrical Conductivity, pH, and Turbidity were determined of the river. using Systronics-Conductometer,Digital Systronics pH – meter and Turbidity –meter, respectively.

Standards methods were iver Kaveri rises from the Western Ghats range in employed for determination of various parameters [12].The Karnataka. It is one among the sacred rivers in India WHO and ISI standards are listed in Table 1. R and is a lifeline of South India. Its water is shared by two Indian states Karnataka and Tamilnadu for Farming and Irrigation. River Kaveri has a wonderful history beginning III. DETERMINATION OF WATER QUALITY from prehistoric ages.

The conclusion is national and international touristsin the state throughout the drawn after making a thorough comparison of the present year. Kaveri has many tributaries namely Hemavathi, Honnuhole, Arkavathy, Kapila, lakshmanaTheerth, Kabini, data with the standard values.

RESULTS AND DISCUSSION have contributed to pollute the river water and affect the quality of the river water. This study was aimed at assessing the changes in water quality as it flows from its place of The water quality was analyzed by collecting samples at two origin in Coorg to Mysore. An extensive literature survey different places. Sample-1 (S1) and Sample-2 (S2) near the revealed that several workers have so far studied the water Mysore city and the Coorg city respectively.
