“…It would also possibly migrate to groundwater from salt pan activities happening along the eastern part of the study area (Chandrasekharan et al 1997 in the groundwater may also arise from the use of fertilisers. In addition, it can also come from apatite mineral found in HBG and charnockite (Brindha et al 2012;Chidambaram et al 2012). One of the reasons for the high bicarbonate in the study area is the high rate of the dissociation of H 2 CO 3 (Rafique et al 2015).…”

“…Water with a high pCO 2 of around − 2 indicates deep circulation of groundwater with a lesser amount of atmospheric contact or higher saturation of carbonate minerals. This results from the interaction of minerals present in the rocks through which it flows (Ayoob and Gupta 2006;Chidambaram et al 2012). It is also evident that log pCO 2 values linearly decreases with pH indicating fresh water recharge or less atmospheric interaction with the system .…”

“…Ion exchange has been found to influence fluoride levels through both base exchange, which reduces calcium concentrations (Edmunds and Smedley 2005;Chae et al 2006) and anion exchange, in which OH − in groundwater replaces F − on certain clay minerals or weathered micas (Guo et al 2007). Thermodynamics computation indicated that some of this high fluoride groundwater is supersaturated with respect to fluorite, fluorapatite and hydroxyl-apatite Chidambaram et al 2012;Li et al 2015). The overuse of fertiliser on the soil for agricultural activities would also be the possible source for the high fluoride and bicarbonate content in groundwater Gao et al 2016a, b).…”

This paper reports the results of higher F − and HCO − 3concentrations and its response to high pH level in a hard rock terrain in Tamil Nadu, India. About 400 groundwater samples from the study area were collected from a period of four different seasons and analysed for F − , HCO − 3and other major cations and anions. The key rationale for the higher fluoride and bicarbonate in the study area is the soaring rate of the leaching fluoride-bearing minerals and weathering processes. Fluoride and HCO is linearly correlated with F − which indicates that these ions were consequent from the weathering influences. At the same time, poor correlation of F − with pH could possibly be due to the increase of alkalinity follow-on from the swell of bicarbonate level with very low Ca 2+ that promotes increase in F − concentration in the groundwater.

“…In India and Sri Lanka, fluorosis is linked to fluoride-rich alkaline groundwaters (Dissanayake 1996;Susheela 1999), and in China, problems are associated with high fluoride groundwaters and inhalation of fluoride from coal smoke (Zheng et al 1999). The prevalence of fluorosis is mainly due to the intake of large quantities of fluoride through drinking water and is reported in many states of India (Siddiqui 1955;Jolly et al 1973;Teotia and Teotia 1991;Susheela et al 1993;Karthikeyan et al 1996;Chidambaram et al 2012;Singaraja et al 2012Singaraja et al , 2014). An evaluation of quality of the groundwater is an important task to be done in a scientific way which requires a simple and valuable tool for decision-making on the groundwater quality.…”

The present study demonstrates a GIS-based spatial evaluation of fluoride contamination (FC) in groundwater vis-a-vis geology and geomorphology of the area using analytical hierarchy process and weighted sum method in Palamu district of Jharkhand. The integration and analyses of the various thematic databases along with the field sampled fluoride data proved useful in delineating the FC zones. The FC index ranged between 141 and 707, and was classified into four zones, viz., low, moderate, high, and very high zones of FC. The FC index map showed that a total of 49.75% of the study area lies between high to very high FC zone. The very high FC zone is found in the moderately weathered plateau with granitic terrain, whereas the high and moderately FC zones covering 49.31 and 36.41% of the study area are dominated by plateau weathered shallow, pediment-inselberg complex, pediplain moderately weathered, pediplain shallow weathered, and inselberg which have high fluoride. The lowest FC zone covers an area of 193.27 sq. km (13.84%). The spatial analysis of geology with fluoride showed that groundwater within granitic gneiss exhibits high FC followed by granitoid gneiss and alluvium. Geomorphologically highest FC was recorded in plateau weathered moderate (91.67%) followed by plateau weathered shallow (71.43%), flood plain (41.76%), inselberg (27.27%), and pediment (25%). The spatial analysis of groundwater yield with fluoride showed that regions having good yield exhibit maximum FC thereby accelerating the vulnerability of the population to fluorosis.

“…and anthropogenic sources (chemical fertilisers, sewage, sludge, etc.) in India are mainly responsible for higher content of F -in groundwater with a combination of higher rate of evaporation and longer interaction of water with aquifer materials under alkaline environment (Ramamohana Rao et al 1993;Wodeyar and Sreenivasan 1996;Chatterjee and Mohabey 1998;Subba Rao et al 1998a, b, 2012Sumalatha et al 1999;Kundu et al 2001;Saxena and Ahmed 2003;Subba Rao and John Devadas 2003;Sujatha 2003;Bhagavan and Raghu 2005;Sreedevi et al 2006;Madhnure et al 2007;Shaji et al 2007;Srinivasamoorthy et al 2008Srinivasamoorthy et al , 2012Ramachandran et al 2012;Reddy et al 2010;Deepu and Shaji 2011;Chidambaram et al 2013;Manikandan et al 2014 ?

Fluoride (F -) content varies from 0.60 to 1.80 mg/L in the coastal region between Chirala and Ongole of Andhra Pradesh, India. It exceeds the threshold limit of 1.20 mg/L in 20 % of the total groundwater samples. The aim of the present study is to assess the controlling factors of F -content. The study area experiences a dry climate and is underlain by Charnockite Group of rocks over which the river and coastal alluvium occur. The
