Geochemistry and Genesis of Fluoride‐Containing Ground Waters in India
Abstract
The fluoride content of ground water in India varies considerably. Among factors which control the concentration of fluoride are the climate of the area and the presence of the accessory minerals, fluorite and (or) apatite in the rock mineral assemblage through which ground water is circulating. Regional and tectonic factors also play some part in affecting the fluoride concentration of ground waters. In general, there is a negative correlation between calcium and fluoride concentrations and a positive correlation between fluoride and bicarbonate concentration in ground waters with high fluoride content. Thermodynamic calculations show that some of these high fluoride ground waters are supersaturated with respect to fluorite. In water sources from Rajasthan, high fluoride concentrations are generally accompanied by high nitrate concentrations. A solution‐evaporation‐base exchange hypothesis is put forward to explain the genesis of these ground waters. In some parts of India, the fluoride content of ground waters is below 0.5 mg/1, indicating that fluoridation of water supplies may be desirable in these places.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
