“…In this scenario, the quality of groundwater has become a major concern throughout the globe. Several studies were attempted by researchers universally to establish the quality of groundwater for various purposes (Wu et al 2015;Asare et al 2016;Singh et al 2015;Nag and Lahiri 2012;Lakshmanan et al 2003;Srinivasamoorthy et al 2009;Gopinath et al 2014;Sridharan and Senthil Nathan 2017;Kattan 2018;Iqbal et al 2018;Sefie et al 2018;Reddy et al 2019;Shamsuddin et al 2019).…”

Coastal areas provide the largest avenue for human settlement worldwide. Among the different sources of water, groundwater comes under the most exploited for domestic, agriculture as well as industrial purposes. The present study is aimed to evaluate the hydrochemical characteristics and quality of groundwater. A total of 132 groundwater samples were collected during post-monsoon and pre-monsoon seasons and analyzed for major and minor ions, and the results were used to evaluate water quality parameters like sodium absorption ratio, magnesium absorption ratio, soluble sodium percentage, permeability index and residual sodium carbonate to establish water quality for various utilities. Groundwater samples show acidic to alkaline nature; dominant cations reported were in the order of Na + > Ca 2+ > K + > Mg 2+ and dominant anions Cl − > HCO 3 − > SO 4 2−. The hardness of water ranges from soft to very hard. The major water types noted were CaHCO 3 , NaHCO 3 , CaCl 2 , mixed CaNaHCO 3 and NaCl. Based on electrical conductivity, total dissolved solids and total hardness majority of the samples are appropriate for consumption and domestic utilities with few exceptions. Computed parameters reveal that a majority of the groundwater samples are suitable for agricultural purposes. The Gibbs plot reveals that interaction between rock and water is the major mechanism controlling groundwater chemistry in the study area. Multivariate statistical analyses such as correlation analysis and principal component analysis were carried out for better understanding and classification of water quality and factors which control the groundwater chemistry.

“…Groundwater samples were collected from nine sources located around the author’s university, which had fluoride content above the permissible limits. The properties of these collected water samples were analyzed, and the details of this are tabulated in Table . − The applicability of CTNC in defluoridating real water samples was investigated in terms of the adsorption efficiency of CTNC; stability of the adsorbent in terms of leaching of metal ions from CTNC post adsorption; and regeneration capacity of the adsorbent while defluoridating groundwater samples.…”

Ceria-incorporated trititanate nanotube composite (CTNC) was synthesized via a simple two-step wet chemical route for efficient fluoride removal not only from synthetic water but also from groundwater. The synthesized nanomaterial was systematically characterized for its physical and chemical properties. CTNC was shown to be highly porous with a surface area of 267 m2/g. The high surface area exposed majority of its adsorption sites, that is, surface hydroxyl groups, for fluoride removal. The plausible adsorption mechanism deduced based on FTIR and XPS data showed that ion exchange between the surface hydroxyl groups and the fluoride ions in water played a vital role in defluoridation by CTNC. A novel approach was used to quantify the adsorption sites with the use of BET and thermogravimetric analysis. TEM images confirmed the morphology of CTNC to be nanotubes decorated with ceria particles. The analysis of treated water samples for the metal ion content was carried out by an ICP-MS technique. CTNC exhibited characteristics of an ideal adsorbent such as high adsorption capacity, faster kinetics, pH independent adsorption, good regeneration, and negligible leaching of metal ions into the effluent. These attractive characteristics enabled the applicability of CTNC for real-time use.

“…In India, fluorosis is endemic in at least 20 states [ 13 , 14 ]. The principal source of drinking water is groundwater for rural populations [ 15 ], fluoride concentration levels varying depending on geographic localization. Although several studies examined the problem of fluorosis in Indian states [ 16 , 17 ], there is a need for prevalence studies in specific regions whose populations share the sociocultural environment as well as weather and geography, in order to generate relevant information about the long-term effects of the fluoride ingested for several generations.…”

Dental fluorosis affects the quality of life. A cross-sectional, observational study was conducted in a community affected by endemic fluorosis for several generations with a conserved biological and social environment. The study included patients from the rural population of Anantapur, India. The Dean index (DI) and the Thylstrup and Fejerskov Index (TFI) were used for fluorosis classification. Additionally, water samples were collected for fluoride analysis, taken from the patients’ living areas. The statistical association between the variables was analyzed. In total, 785 patients between 10 and 60 years old were included in the study (58.7% women and 41.3% men). Fluorosis signs were found in 94.6% of patients examined using the DI and 94.4% using the TFI. Moderate–severe dental fluorosis was observed in 62.8% by DI and 73.1% by TFI consuming untreated water with up to 2.9 ppm of fluoride. Furthermore, moderate–severe dental fluorosis was observed in 33.2% by DI and 39.9% by TFI consuming water with ≤1.5 ppm of fluoride. The high prevalence of moderate–severe dental fluorosis in patients consuming water with a low fluoride concentration suggests that other factors are involved. Biological susceptibility change could play an essential role in the severity of dental fluorosis in populations exposed for several generations, affecting its actual and future quality of life.
