FLUORIDE GEOCHEMISTRY OF GROUNDWATER IN NALHATI-1 BLOCK OF THE BIRBHUM DISTRICT, WEST BENGAL, INDIA

Summary: The concentration of fluoride ion (F) in groundwater samples from different sites in Nalhati-1 block of the Birbhum district, West Bengal, was determined by SPADNS colorimetric analysis. Most of the F levels were within permissible limits, whereas a significantly higher concentration of 1.95 mg/L was found in artesian well samples of Nasipur village. The F in groundwater appears to be controlled by the distribution of Ca 2+ and to some extent SO4 2– , ionic strength, and the presence of complex ions. From correlation coefficient analysis, F was found to be inversely related to Ca 2+ and positively related to Na + . Basaltic rock and water interaction with it may be responsible for the increased F in the artesian well samples from the study area.
