FLUORIDE ION CONCENTRATION IN THE GROUND WATER OF TIRUCHIRAPPALLI DISTRICT, TAMIL NADU

摘要

Water samples were collected from Tiruchirappalli District and analysed for fluoride ion concentration and also for other water quality parameters. It is observed that high alkalinity leads to increase in the fluoride level and high calcium content decreased the fluoride level. The minimum value of fluoride ion concentration was observed as 0.56 mg/l in Kottapattu and maximum value was 3.89 mg/l in Kodumbalur.
