The Kallanai Dam is situated at twelve km north from Tiruverumbur, Trichirappalli of Tamilnadu District. Kallanai Dam belongs to Thanjavur District of the same state. All agriculture land in and around Tiruchirappalli and Thanjavur is being benefited only by Cauvery river. The main reservoir for these lands is Kallanai Dam.

Among 4 samples, 2 from river at two different season and 2 from bore well at same season. The parameters such as pH, EC, total dissolved salt (TDS), biological oxygen demand (BOD), chemically oxygen demand (COD), Total Hardness, Sulphate, Chloride, Nitrate, Calcium, Magnesium, Sodium, Potassium and heavy metals such as Cadmium, Mercury, Iron, Zinc, and Nickel are analyzed by suitable methods.
