“…The fluoride levels of sediment core and groundwater Sediment core has fluoride levels of 130-468 mg/kg, with mean of 324 mg/kg (Figure 2). Fluorine in rock, soil or sediment is generally considered to determine groundwater fluoride levels (Usham et al 2018;Chen et al 2020a). However, the sediments in Buzhuang Town have lower fluoride levels than the average soil (sediment) fluoride level in China (478 mg/kg), soil fluoride levels in Shandong province (499 mg/kg) (Chen et al 2020a).…”

Therefore, the sediment fluoride level itself can't well explain the high-fluoride groundwater in Buzhuang Town.…”

“…Actually, the pH in the local groundwater also shows higher levels than in the supplied water, which may be one of the reasons for its higher fluoride levels. In addition, the high salinity, TDS, conductivity and harness due to seawater intrusion are benefit for the fluoride-leaching from the sediment/rocks and fluoride-enrichment in groundwater (Gao et al 2007;Chen et al 2014Chen et al , 2020a.…”

Seawater intrusion and drinking-water fluorosis are frequently documented along coastal plains. Groundwater is characterized by high OH−, Na+, total dissolved solids, and low Ca2+ because of seawater intrusion, and such conditions favor sediment fluoride-leaching and fluorosis. But the geological process of seawater intrusion has not been noticed when high-fluoride groundwater along coastal areas is discussed. The groundwater and sediments in a typical seawater intrusion and fluorosis area are gained, and fluoride-leaching simulation experiments are performed. Sediment fluoride levels are equal to or lower than average sediment fluoride levels in China and Shandong province, but strong fluoride-leaching in aquifers is observed. Compared with the supplied water from the non-intruded neighboring area, the local groundwater has higher fluoride levels, together with higher pH, total dissolved solids, HCO3−, Cl−, Br−, SO42−, Na+, K+, and low Ca2+ because of seawater intrusion. Aquifer sediment fluoride-leaching ability increases with an increase in seawater (brine water) mixing ratios, and NaCl or NaHCO3 levels, but with a decrease in CaCl2 levels. This directly confirms that seawater (brine water) intrusion promotes sediment fluoride-leaching, and the high pH, Na+, HCO3−, and low Ca2+ levels caused by seawater intrusion are responsible for the high-fluoride groundwater along coastal plains.

Water is most essential natural resource on earth and we cannot live without it. Contamination of water is increasing day by day. In Punjab, India water is not safe for drinking, it can be cause of many harmful diseases. It mainly affect human kidney. In present research, work is done to find the characteristics of the ground water collected from Phagwara Region, Punjab. Analysis was done using different spectroscopic techniques, mainly - Fourier Transform Infra-Red and Fluorescence spectroscopy. It was observed that the sample contained strong narrow C-C triple bond, N-H bond is also present. The two spectroscopic techniques were successful in characterizing the bonds present in the sample under research.
