“…6d, the correlation of fluoride and calcium, this clearly indicates that the presence of high calcium content favored low fluoride concentration in the groundwater. It is observed that the major role of precipitation process that is a vital mechanism for enhancement of fluoride occurrence in groundwater (Adimalla et al 2018a;Sudarshan 2017b, 2018a, b;Li et al 2018) and negative relations of fluoride with magnesium ( Supplementary Fig. 1) is an agreement as established by Reddy et al 2016.…”

“…For understanding the relation between fluoride and other chemical parameters, correlation plots provide significant geochemical information and also help to know the controlling factors and its mechanism of fluoride enrichment in the groundwater (Adimalla et al 2018a;Wu et al 2019). A moderate positive correlation is observed between fluoride and pH ( Fig.…”

“…In general, fluoride is released into groundwater from fluorine-bearing minerals such as fluorite, fluorapatite, biotite, apatite, muscovite, hornblende, villiaumite, tremolite, sellaite, cryolite, topaz, fluocerite, yttrofluorite, gagarinite, bastnasite, microlite, sphene, wohlerite, fluormica, epidote, amphibole, Electronic supplementary material The online version of this article (https ://doi.org/10.1007/s1320 1-019-0968-y) contains supplementary material, which is available to authorized users. lepidolite, montmorillonite, kaolinite, pegmatite, mica, clays, villuanite, phosphorite, and some micas weathered from silicates, igneous, and sedimentary rocks, especially shale (Adimalla et al 2018a;Ayoob and Gupta 2006;Sudarshan 2017a, 2018a, b), and high rates of evaporation and low precipitation in arid and semiarid areas can also contribute to the fluoride enrichment Venkatayogi 2017, 2018;Subba Rao et al 2015). However, fluoride is an important element for human health which has certain limits for intake (Rao et al 2017;Ali et al 2016;Narsimha and Sudarshan 2017a, b).…”

In total, 123 groundwater samples were collected to evaluate the suitability for drinking purpose in a rural part of Andhra Pradesh, India. The groundwater is alkaline in nature and pH varying from 7.18 to 9.32 with a mean value of 8.36. The hydrogeochemical analysis reveals that the fluoride concentration varies from 0.4 to 5.8 mg/L with a mean of 1.98 mg/L. Higher fluoride concentration is found in west-central parts of Markapur region. The villagers have been exposed to the intake of high fluoride-bearing groundwater for the prolonged period and suffering from the deadly disease fluorosis. However, with respect to groundwater chemistry, the fluoride concentration is high in Na + -HCO 3 − -type groundwater and low in Ca 2+ -HCO 3 − -type groundwater in the Markapur region. Data plotted in Gibbs diagram show that all groundwater samples fall under rock weathering dominance group with a trend toward the evaporation dominance category. Therefore, rock-water interaction is the primary cause of elevated fluoride in the groundwater of the study region. Furthermore, a significant positive correlation exists between F − and pH, HCO 3 as well as negative correlation exists between Fand Ca 2+ and NO 3 − , which supports that the alkaline nature of water is the main cause for dissolving fluoride-bearing minerals.

“…Fluoride (F − ) is an essential element for human body when consumed in low amount (< 1.5 mg/L) and excess intake of F − (> 1.5 mg/L) will have adverse effects on human health (Adimalla and Venkatayogi 2017;Adimalla et al 2018b, c;Narsimha and Sudarshan 2017a, b). Furthermore, continually consumption of water with fluoride concentrations above 1.5 mg/L results in dental fluorosis characterized initially by opaque white patches, staining, mottling and pitting of teeth (Adimalla et al 2018c;Narsimha and Rajitha 2018;Narsimha 2018;Kundu et al 2001). Moreover, F − concentration in surface water and groundwater of the study area varied from 0.63 to 0.81 mg/L and 0.84 to 1.85 mg/L, with mean value of 0.69 and 1.22 mg/L, respectively (Tables 2, 3).…”

The present study confers the chemical quality of groundwater and surface water of Mothkur region, Telangana State, for drinking and irrigational purposes. Mothkur region is geologically occupied by the Archaean crystalline terrain. Most of the population depends on groundwater for their daily needs especially for drinking, house needs and irrigation purposes. For this reason, twenty-five groundwater and five surface water samples were collected and analysed for pH, electrical conductivity, total dissolved solids (TDS), total hardness (TH) bicarbonate (HCO 3 − ), chloride (Cl − ), sulphate (SO 4 2− ), fluoride (F − ), calcium (Ca 2+ ), magnesium (Mg 2+ ), sodium (Na + ) and potassium (K + ). The results are evaluated and compared with WHO and BIS water quality standards. Based on obtained results 32%, 20%, 28% and 4% of groundwater samples are not recommended for drinking with reference to the concentrations of fluoride, TDS, TH and Cl − , respectively. Base-exchange indices and meteoric genesis indices classified 67% and 33% of the water sources as the Na + -HCO 3 − type and deep meteoric water percolation type, respectively. Piper trilinear diagram for geochemical classification indicates 44% and 60% of groundwater and surface water samples of Ca 2+ -Na + -HCO 3 − type and 29% belong to Na + -HCO 3 − types. Multivariate graphical methods have been carried out using the United States Salinity Laboratory diagram, Wilcox diagram, sodium adsorption ratio, per cent sodium (%Na), residual sodium carbonate and permeability index which indicate that majority of groundwater samples are useful for irrigation purposes.Keywords Hydrochemistry · Groundwater quality · Sodium adsorption ratio (SAR) · Per cent sodium (%Na) · Residual sodium carbonate (RSC) · Permeability index (PI) · Mothkur region · South India Electronic supplementary material The online version of this article (https ://doi.

In this study, the spatial distribution of fluoride, uranium, and associated water quality parameters in the drinking water of the Cuttack district, Odisha, India, has been analyzed. A total of 104 groundwater samples were collected and analyzed. The experimental data were analyzed by statistical techniques and the universal inverse distance weighting model. The pH of the collected groundwater samples is mainly regulated by the presence of HCO 3 − alkali species. The fluoride concentrations in 34.6% of the samples exceeded the Bureau of Indian Standards' acceptable limit. The health risk assessment was conducted as per guidelines of the U.S. Environmental Protection Agency.The noncarcinogenic health risk of fluoride is the maximum and is followed by nitrate.Almost 56.73% of water samples are classified under the noncarcinogenic health risk category, and 1.9% of samples exhibit a carcinogenic health risk for both adults and children. The noncarcinogenic health risk for children is higher than for adults. pH was positively correlated with fluoride with a correlation coefficient of 0.287, which indicated that the higher pH augmented the displacement of fluoride ions from the mineral surface. HCO 3 − and Ca 2+ are moderately correlated with a correlation coefficient of 0.372, but HCO 3 − is negatively correlated with Mg 2+ (r = −0.049), indicating that calcite dissolution and/or precipitation is much higher than dolomite.
