Assessment of water quality and occurrence of fluoride in groundwater of various villages of district Ambala (Haryana)

The present work aims to study the level of fluoride in bore well, hand pump water samples of different villages of Mullana block, District Ambala, state Haryana & also to analyzed other water qualities parameters like pH, sulphate ions, chloride ions, total hardness, nitrite ions, methyl orange alkalinity, fluoride ion, iron, copper and cadmium. The analysis showed a minimum fluoride level of .02mg/l and maximum level of .77 mg/l in tube well water of different villages. In Dulyani village of Ambala district showed minimum fluoride concentration of 1.72mg/l and maximum of 1.98mg/l. This water sample was found to be exceeded the WHO 1995 drinking water standards and it reflects on health status of the consumers. Fluorides are known to be beneficial when present in concentration of 0.5 to 1.5mg/l. But when it exceeds the limits of 1.5mg/l it is found to cause fluorosis.
