“…F -is an essential micronutrient for human health taken in small quantities (0.5-1.0 mg/L), serving to strengthen the apatite matrix of skeletal tissues and teeth (Sharma et al 2012;Rafique et al 2009). The F -concentration in groundwater of pre-monsoon ranges from 0.010 to 0.215 meq/L, 0.005-0.210 meq/L in monsoon, and 0.010-0.200 meq/L in the post-monsoon season.…”

The hydrochemical study of groundwater in Karur district of the Amaravathi River basin has been carried out to assess the major ion chemistry and groundwater quality for domestic and drinking purposes. Twenty-four groundwater samples were collected, processed, and analyzed for various physico-chemical parameters such as pH; electrical conductivity; total dissolved solids; total hardness; cations such as calcium, magnesium, sodium, and potassium; anions such as bicarbonate, chloride, sulfate, fluoride, nitrate, and phosphate in the laboratory using the standard methods given by the American Public Health Association (Standard methods for the examination of water and wastewater, 21st edn. American Public Health Association, Washington DC, 2005). For quality assessment, the results were compared with water quality standards prescribed by the Bureau of Indian standards (Indian standards specification for drinking water 15:10500. Bureau of Indian Standards, New Delhi, 2003) Concerning water for irrigation purposes, parameters such as percent sodium (% Na), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), chloro-alkaline indices (CAI I and CAI II), permeability index (PI), magnesium hazard (MH), Kelley's ratio (KR), USSL diagram, Gibbs' ratio (GR), and Wilcox diagram were calculated on the basis of chemical data to evaluate the current status of groundwater in the Amaravathi River basin. Parameters like MH (74 %), KR (75 %), RSC (95 %), and PI (69 %) in all three seasons indicate that the samples are suitable for irrigation and remaining are unsuitable. From USSL diagram, the result reveals that the samples fall in C3-S1 and C4-S1 indicate high to very high-salinity and lowsodium hazards. Wilcox diagram revealed out of 24 samples, sample no. 7, 8, and 11 in pre-monsoon, monsoon, and postmonsoon seasons fall under doubtful to unsuitable and 9 fall under unsuitable zone. The positive CAI values in 66 % samples in all three seasons indicate reverse ion exchange mechanism. The present study may be helpful for further studies concerning water quality issues in this area, where groundwater is a vital for drinking and other activities.

“…Fluorite (CaF 2 ) is the sole principal mineral of fluorine occurring in nature, and is commonly found as an accessory in granitic gneiss (Ozsvath 2006;Saxena and Ahmed 2003). Fluorine is also abundant in other rock-forming minerals like apatite, micas, amphiboles, and clay minerals (Karro and Uppin 2013; Narsimha and Sudarshan 2013; Rafique et al 2009;Naseem et al 2010;Jha et al 2010;Carrillo-Rivera et al 2002).…”

Hydrogeochemical investigation has been carried out in the granitic terrain of Siddipet area, Medak district, Telangana State, India with an aim to understand the distribution of fluoride in the groundwater and to understand the relationship of fluoride with other major ions, and also to identify the high fluoride-bearing groundwater zones. 104 groundwater samples were analyzed in the study area for fluoride and other major ions like calcium, magnesium, chloride, carbonate, bicarbonate, sodium, potassium, sulfate, and nitrate in addition to pH and electrical conductivity. The studies revealed that the concentration of fluoride in groundwater is ranging from 0.2 to 2.2 mg L -1 with a mean of 1.1 mg L -1 . Nearly 22 % of groundwater has more than the permissible limit of fluoride (1.5 mg L -1 ), which is responsible for the endemic dental fluorosis in the area concerned. Geochemical classification of groundwater shows that Na-HCO 3 , Ca-Cl, and Ca-HCO 3 -Na are the dominant hydrochemical facies. Gibbs diagram shows rock-water interaction dominance and evaporation dominance, which are responsible for the change in the quality of water in the hard rock aquifer of the study area. The groundwater in villages and its environs are affected by fluoride contamination, and consequently majority of the population living in these villages suffer from dental fluorosis. Hence, they are advised to consume drinking water which has less than 1.5 mg L -1 fluoride to avoid further fluorosis risks.
