A study on water quality assessment and its treatment over CNSL resin has been planned. Water samples from various sources like bore well, ground water, municipal water, stagnated water and rain water were collected from seven locations in and around Marudhur of Villupuram. These seven samples were analyzed for various parameters such as TDS, pH, total hardness, Calcium hardness, Magnesium hardness, Iron, nitrate, chloride, sulphate and alkalinity in a well-equipped laboratory as per standard methods. After analyzing the seven samples the results revealed the nature of samples. i.e., whether they are scale forming or corrosive or neutral water which was found using Langlier and Rayznar indexes. Even the probable combination method was employed to check the correctness of determination of various parameters and found to be correct. Out of seven samples four samples (sample 1, 2, 3 and 5) where found to have more hardness they were taken for analysis with CNSL resin. The CNSL resin was prepared in the laboratory and the samples agitated with the CNSL resin. Analysed the samples and found the hardness were reduced. The results show that the percentage of removal of cation increases when adsorbent dose increases.
