“…Physicochemical parameter values of the surface water samples analysed in the Birim River basin are presented in × 100 low TDS concentration in the water samples is due to the short residence time of the underground rocks as well as the slow weathering of granitic (Patel et al 2016). The EC and TDS concentrations of all the river water samples are very much below the WHO acceptable limit of 500 μS/ cm and < 600 mg/L, respectively (WHO 2011).…”

Background: Geogenic and anthropogenic activities such as Artisanal and illegal gold mining continue to have negative impacts on the environment and river basins in China. This work studied the hydrogeochemical characteristics of surface water from the Birim River basin and assess the quality of water for human consumption and agricultural activities. In addition, the ecological risk assessment for Cd, Zn, Pb and As in sediment was evaluated using pollution indices. Results:The results show that the turbidity, temperature, colour and iron concentration in the water samples were above the World Health Organization guidelines. Multivariate analysis explained five components that accounted for 98.15% of the overall hydrogeochemistry and affected by anthropogenic and geogenic impacts. The surface water was observed to range from neutral to mildly acidic, with the dominance of HCO 3, and Na + in ionic strength. The Piper diagram reveals five major surface water types: Na-HCO 3 -Cl, Na-Cl-HCO 3 , Na-Ca-Mg-HCO 3 , Na-Ca-Mg-HCO 3 and Ca-Na-Mg-HCO 3 . The Gibbs plot showed that the major ion chemistry of surface water was mostly influenced by atmospheric precipitation and the water quality index showed that the majority of the surface water from settlements within the Birim River basin were of poor quality for drinking and other domestic purposes. However, irrigation suitability calculations with reference to sodium adsorption ratio, residual sodium carbonate, and magnesium ratio values, together with Wilcox and USSL models indicated that the surface water within the area under study was suitable for agriculture. The potential ecological risk for single heavy metals pollution and potential toxicity response indices gave low to considerable ecological risks for the sediments, with greater contributions from Cd, Pb and As. Whilst geo-accumulation indices indicated that the sediments ranged from unpolluted to moderately polluted Modified degree of pollution and Nemerow pollution index calculations which incorporate multi-element effects, however, indicated no pollution. Conclusion:There are some levels of both potential ecological risks and health hazards in the study area. Hence continuous monitoring should be undertaken by the relevant agencies and authorities so that various interventions could be put in place to prevent the situation from deteriorating further in order to protect the inhabitants of the settlements within the Birim River basin.

“…Therefore, monitoring of groundwater quality is essential in any basin or population area which affects the fittingness of water for household, industrial and agriculture use. Many researchers have worked on hydrochemical features, groundwater pollution, and its quality status for utilization in drinking and agriculture purposes in various basins and urban regions (Ahamed & Loganathan, 2017;Alaya, Saidi, Zemni, & Zargouni, 2014;Gowd, 2005;Patel et al, 2016;Raju, Ram, & Gossel, 2014;Raju et al, 2016;Singh, Tewary, & Sinha, 2011;Umar, Ahmed, Alam, & Khan, 2008). In the current study, an effort has been made to calculate the groundwater quality indices for the aptness of groundwater resource for drinking and agricultural purpose and identify the influences of natural and anthropogenic actions on groundwater chemistry.…”

This study is aimed to assess the groundwater excellence within the rural areas of Sant Ravidas Nagar (Bhadohi), Uttar Pradesh, India. In the current work, estimation of groundwater excellence indices has been done to recognize the water quality for the appropriateness of groundwater resource for drinking and agricultural use. Twenty groundwater samples were collected and investigated for diverse geochemical parameters viz, pH, total dissolved solids (TDS), total hardness, cations and anions. The groundwater of the study region is neutral to slightly alkaline in nature. Piper's diagram classification shows that majority of the samples belong to CaMgHCO 3 hydrochemical facies. Gibbs plot specifies that majority of samples falls in rock dominance. The water quality index shows that the entire sample is under excellent water category. On the basis of TDS, all the samples are within the range of desirable to permissible for drinking and agriculture purpose. Forty percent samples of the study region are having nitrate content more than permissible limit (>50 mg/l) which is not fine for individual use. Poor drainage, domestic waste and use of N fertilization on farming land may be the main sources of nitrate in groundwater of the study region. On the basis of different water quality indices, groundwater of the study region is fit for agricultural use.

“…It is the main inorganic toxicant of fluorine, predominantly promoted by alkaline pH, high concentrations of sodium cations (Na + ) and bicarbonate (HCO 3 − ), and low concentrations of calcium ions (Ca ++ ) (Guo et al, 2007;Rafique et al, 2009). Fluoride enrichment mostly occurs in groundwater, soil, rocks, food, air, flora, fauna, and the human body (Rakshit, 2004;Raju et al, 2012;Varol et al, 2013;Raju et al, 2014;Singh et al, 2015;Xiao et al, 2015aXiao et al, , 2015bPatel et al, 2016). Groundwater is the principal source of F − for human ingestion, potentially recognized and controlled by the regional chemistry of the host rock, hydrogeology, anthropogenic activities, and climatic factors (Frengstad et al, 2001;Saxena and Ahmed, 2003;Edmunds and Smedley, 2005;Chae et al, 2007;Khaliq et al, 2007;Rafique et al, 2009;Singh et al, 2015).…”

This study investigated the fluoride (F) concentrations and physicochemical parameters of the groundwater in a fluorite mining area of the flood plain region of the River Swat, with particular emphasis on the fate and distribution of F and the hydrogeochemistry. To better understand the groundwater hydrochemical profile and F enrichment, groundwater samples (n=53) were collected from shallow (24-40m), mid-depth (48-65m) and deep (85-120m) aquifers, and then analysed using an ion-selective electrode. The lowest F concentration (0.7mg/L) was recorded in the deep-aquifer groundwater, while the highest (6.4mg/L) was recorded in shallow groundwater. Most groundwater samples (62.2%) exceeded the guideline (1.5mg/L) set by the World Health Organization (WHO); while for individual sources, 73% of shallow-groundwater samples (F concentration up to 6.4mg/L), 42% of mid-depth-groundwater samples, and 17% of deep-groundwater samples had F concentrations that exceeded this permissible limit. Assessment of the overall quality of the groundwater revealed influences of the weathering of granite and gneisses rocks, along with silicate minerals and ion exchange processes. Hydrogeochemical analysis of the groundwater showed that Na is the dominant cation and HCO the major anion. The anionic and cationic concentrations across the entire study area increased in the following order: HCO>SO>Cl>NO>F>PO and Na>Ca>Mg>K, respectively. Relatively higher F toxicity levels were associated with the NaHCO water type, and the chemical facies were found to change from the CaHCO to (NaHCO) type in calcium-poor aquifers. Thermodynamic considerations of saturation indices indicated that fluorite minerals play a vital role in the prevalence of fluorosis, while under-saturation revealed that - besides fluorite minerals - other F minerals that are also present in the region further increase the F concentrations in the groundwater. Finally, a health risk assessment via Dean's classification method identified that the groundwater with relatively higher F concentrations is unfit for drinking purposes.
