“…The over dependence on groundwater for drinking, agricultural and industrial sector and different climatic and natural phenomenon causes coastal groundwater contamination (Srinivas et al 2015). Besides, different geochemical processes in groundwater governing the chemical characteristics of groundwater, is well documented in many parts of the world by many authors i.e., Montety et al (2008), Jalali (2009), Manjusree et al (2009), Thilagavathi et al (2012, Sivasubramanian et al (2013), Nagaraju et al (2014), Kumar et al (2015), Islam et al (2016a, b) and Balaji et al (2016). Geochemical studies of groundwater provide a better understanding of water quality and possible changes .…”

Hydrogeochemical investigation of groundwater in shallow coastal aquifer of Khulna District, Bangladesh

Groundwater acts as a lifeline in the coastal regions to meet out the domestic, drinking, irrigational and industrial needs. To investigate the hydrogeochemical characteristics of groundwater and its suitability, twenty samples were collected from the shallow tubewells of study area having screen depth 21-54 m. The water quality assessment has been carried out by evaluating the physicochemical parameters such as temperature, pH, EC, TDS and major ions i.e., Na -, respectively and Na-Cl-HCO 3 is the dominant groundwater type. The analyzed samples were also characterized with different indices, diagram and permissible limit i.e., electric conductivity (EC), total dissolved solids (TDS), chloride content (Cl), soluble sodium percentage (SSP), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), magnesium adsorption ratio (MAR), Kelley's ratio (KR), Wilcox diagram and USSL diagram, and results showed that groundwater are not suitable for drinking and irrigational use. The factors responsible for the geochemical characterization were also attempted by using standard plot and it was found that mixing of seawater with entrapped water plays a significant role in the study area.

Evaluation of groundwater contamination for fluoride and nitrate in Nellore Urban Province, Southern India: a special emphasis on human health risk assessment (HHRA)

et al. 2022

Groundwater pollution with fluoride and nitrate is one of the most serious issues in coastal regions. Thirty-nine groundwater samples were collected in the current research region and tested for PH, TDS, and EC. Thirty-nine groundwater samples were collected in the current research region and tested for PH, TDS, EC and cations, anions, and hardness. The elevated parameters are EC, PH, TDS, and nitrates. The fluoride fell in the permissible limit in Nellore urban area, nitrate and fluoride exposure heath risk calculated by using the US EPA method. From that, the total hazard index (THI) was calculated. The fluoride total hazard index value ranges from 0.15 to 0.95 and that of average 0.45, which fell below < 1, hence no significance on children, women, and men. The nitrate is falling in excess in groundwater. The ranges are 35 mg/l to 72 mg/l, and adverse value is 47.8 mg/l. The total hazard index (THI) of nitrates fell at > 1, which indicates a harmful for the human health. The computed THI affected percentage is the children (100%), women (95%), and men (30%). The nitrate was released in water due to the industrial discharge, septic tanks, manure pools, sewer system, and rock–water interaction. The abundance of the cations and anions is Ca2+ > Na+ > Mg2+ > K+ and HCO3− > Cl− > SO42 > NO3 > F. The Gibbs diagram explains the source of the chemistry; hence, all samples fell in the rock–water interaction area.

This paper reviews the concentration and distribution of fluoride in Indian groundwater with particular emphasis and similarities between different components. Groundwater is an essential and precious source of water for drinking. Fluoride is frequently found naturally in the groundwater. Through human activities, organic pollutants enter the groundwater are also a significant concern that can not be avoided. The data for this review paper was obtained from nineteen locations from 2007 to 2018. The data revealed that fluoride concentration ranged from 0.26 to 5.636 mg/L, with 37% of sites with a higher fluoride concentration level. Excessive fluoride ingestion contributes to fluorosis of the dentures and skeletons and bone deformities. It is observed that eight sites were found with higher concentrations (>180 mg/L) of hard water minerals out of nineteen sites. The correlation between the elements itself shows a strong positive correlation, which is r= +1 but the correlation of F-, Ca2+, Na+, K+, Mg2+, HCO3-, Cl-, SO42-, NO3-, Fe, Mn, PO43-, CO32- between each other is either strong, medium, or small positive and negative or shows no linear relationship between each other. It was noted that the level of health risk in the district of Dhandband and the state of Telangana was calculated to have a higher risk with greater probability and consequences.
