The geology of Deltaic Region i.e. the arsenic contaminated areas of West Bengal
and Bangladesh is not prone for fluoride contamination. We also analyzed few
hundred water samples for fluoride from delta area and none of them found
contaminated. Only in West Bengal non-deltaic area like Bankura, Birbhum are to
some extent fluoride contaminated and also we expect fluoride in Bangladesh
close to north, that is areas bordering with fluoride contaminated Assam.
