STUDY OF FLUORIDE CONTENT IN GROUND WATER FROM VILLAGES OF PATAN TALUKA OF GUJARAT, INDIA

摘要

Naturally occurring fluoride has been detected and quantified in ground water and surface water in the North Gujarat region. The major source for drinking and irrigation water in North Gujarat is ground water. Ground water comes from the regional alluvial aquifer system. This region is severely affected by endemic fluorosis under water stress [b-12]. With an objective to understand fluoride contamination in groundwater of Patan region groundwater samples have been collected and analyzed for various chemical parameters. In most of the groundwater samples the concentration of fluoride was found to be moderately higher, when compared to the WHO standard for drinking water that is 1.5 mg/L, the results of physico-chemical analysis of water are discussed. Large numbers of people living in the region are under adverse health risk because they consume contaminated drinking water without proper treatment. It is well known that long-term exposure to water with high levels of fluoride produces severe health problems.
