“…It is also observed that high fluoride zones are usually associated with waters enriched in heavy oxygen isotope 18 O (Datta et al 1996;Tirumalesh et al 2007). The linkage among evapotranspiration, heavy oxygen isotope 18 O and fluoride concentration in groundwater was established by Datta et al (1999).…”

Fluoride contamination in water is a major problem across the globe, with health hazards such as dental and skeletal fluorosis. Most earlier studies are confined to local or regional scales. As the problem has serious socioeconomic implications, there is a need for a global perspective. Thus, here we review worldwide research for nearly a century on fluoride contamination in water. We investigated the distribution of fluoride contamination in water, its sources, mobilization and association. The major findings are: (1) Anomalous fluoride concentration in groundwater is mainly confined to arid and semiarid regions of Asia and North Africa. (2) The geogenic sources of fluoride in water are mainly fluorine-bearing minerals in rocks and sediments, whereas anthropogenic sources of fluoride in water are mainly pesticides and industrial waste.(3) Fluoride mobilization from geogenic sources is mainly controlled by alkalinity and temperature. (4) Fluoride occurrence in water is associated with ions such as sodium, arsenic chloride and bicarbonate. There are few associations of fluoride in water with calcium and magnesium.

“…Evaporation is another important factor resulting in the occurrence of high fluoride groundwater (Datta et al 1999). Calcium ions precipitate out as CaCO 3 , due to high evaporation resulting reducing Ca 2+ concentration of the groundwater, and consequently the solubility control of CaF 2 on fluoride enrichment in the aqueous phase becomes weaker.…”

“…High NO 3 contamination in western Texas, resulting from the application of different agrochemicals, has also been reported (Hudak, 2000;Chaudhuri et al, 2012). Although Fis not a constituent of NO 3 fertilizers, coexistence of Fand NO 3 at high levels can be attributed to common sources, such as agrochemicals used in crop production Datta et al, 1999). Nitrate and Freleased from different agrochemicals can leach simultaneously to groundwater systems by the infiltrating rain and irrigation water, leading to a high abundance of both species ).…”

Groundwater quality degradation is a major threat to sustainable development in Texas. The aim of this study was to elucidate spatiotemporal patterns of groundwater fluoride (F) contamination in different water use classes in 16 groundwater management areas in Texas between 1960 and 2010. Groundwater F concentration data were obtained from the Texas Water Development Board and aggregated over a decadal scale. Our results indicate that observations exceeding the drinking water quality threshold of World Health Organization (1.5 mg F L) and secondary maximum contaminant level (SMCL) (2 mg F L) of the USEPA increased from 26 and 19% in the 1960s to 37 and 23%, respectively, in the 2000s. In the 2000s, F observations > SMCL among different water use classes followed the order: irrigation (39%) > domestic (20%) > public supply (17%). Extent and mode of interaction between F and other water quality parameters varied regionally. In western Texas, high F concentrations were prevalent at shallower depths (<50 m) and were positively correlated with bicarbonate (HCO) and sulfate anions. In contrast, in southern and southeastern Texas, higher F concentrations occurred at greater depths (>50 m) and were correlated with HCO and chloride anions. A spatial pattern has become apparent marked by "excess" F in western Texas groundwaters as compared with "inadequate" F contents in rest of the state. Groundwater F contamination in western Texas was largely influenced by groundwater mixing and evaporative enrichment as compared with water-rock interaction and mineral dissolution in the rest of the state.
