Arsenic In Groundwater

Abstract Groundwater is an important water resource used for drinking, domestic and agricultural activities in Akşehir and surroundings. However, intensive agricultural and human activities in the region adversely affect groundwater quality. In this study, 31 water samples were collected from wells. According to the Piper diagram, groundwater in the study area was in the Ca–Mg–HCO3 and Ca–HCO3 water facies. As a result, it is not appropriate to use groundwater as drinking water in the study area in terms of trace elements and pollutant analysis results of water samples compared to limit values determined by WHO and ITHASY drinking water guidelines. The arsenic concentration in groundwater was studied in detail. The origin and concentration of arsenic in groundwater is associated with agricultural activities and pesticides in the region. Accordingly, a health risk assessment was carried out for the use of groundwater in the study area as drinking water. The results for all samples analyzed indicate that the groundwater concerned was not suitable for drinking purposes because of arsenic concentrations which exceeded maximum acceptable levels.

Abstract Water is very important to maintaining life on earth. Fluoride and Arsenic pollution in groundwater is an emerging issue in the world. Atomic absorption spectrometry was used to measure total arsenic, while ion chromatography was used to determine fluoride. The present study was conducted for the health risk assessment of fluoride and arsenic in groundwater around brick kilns. 58 samples of groundwater were collected from district Vehari Punjab and were analyzed for arsenic concentration ranges from 0.330 to 11.120 µg/L, higher than the WHO recommended permissible level of arsenic in drinking water (10 µg/L). The mean value of fluoride in the water supply for drinking is 2.599 mg/L as its concentration ranges are 0.680 to 9.690 mg/L respectively. All the values of fluoride in drinking water were higher than the permissible limit according to WHO standard 1.5 mg/L. The spatial distribution of arsenic and fluoride in groundwater indicates their direct contamination with rock weathering, coal burning, and the use of cheap fuel in brick kilns. The estimated average dose (ADD), hazards quotient (HQ), as well as cancer risk (CR), were computed using statistical formulae to determine the health risks of arsenic and fluoride. The hazard quotient (HQ) values of As and F− in this research area were higher protection and safe limits (HQ > 1), having health risks to the people in this region, caused by brick kilns. Statistical parameters correlation and cluster analysis were used to determining possible contaminant sources in the study area.

This study was carried out to investigate the distribution of selected elements (Ca, Mg, Na, K, Fe, Zn, Cu, Sr, Li, Mn, Co, Cr, Cd and Pb) and physicochemical parameters (pH, dissolved oxygen, electrical conductivity and total alkalinity) in the freshwater of Simly Lake, Pakistan. Multivariate statistical analysis was used to study the apportionment of elements in the water samples, while their suitability for drinking and agricultural purposes were also assessed. Principal component analysis (PCA) and cluster analysis (CA) revealed considerable anthropogenic contributions of the elements in water samples. Average levels of Cd, Co, Cr and Pb in the waters were significantly higher than national and international standards. In order to ascertain the potential health risk of heavy metal contents to the local population, non-carcinogenic health risk assessment was evaluated in terms of exposure assessment (Exping/derm) and hazard quotient (HQing/derm) which demonstrated that the measured levels of Cd, Co, Cr and Pb were higher than the safety limit, thus indicating adverse health effects associated with the consumption of the lake water.

This study investigates the drinking water (groundwater and surface water) quality and potential risk assessment along mafic and ultramafic rocks in the Swat district of Khyber Pakhtunkhwa Provence, Pakistan. For this purpose, 82 groundwater and 33 surface water samples were collected and analyzed for physico-chemical parameters. Results showed that the majority of the physico-chemical parameters were found to be within the drinking water guidelines set by the World Health Organization. However, major cationic metals such as magnesium (Mg), and trace metals (TM) including iron (Fe), manganese (Mn), nickel (Ni), chromium (Cr) and cobalt (Co) showed exceeded concentrations in 13%, 4%, 2%, 20%, 20% and 55% of water samples, respectively. Health risk assessment revealed that the non-carcinogenic effects or hazard quotient values through the oral ingestion pathway of water consumption for the TM (viz., Fe, Cr and Mn) were found to be greater than 1, could result in chronic risk to the exposed population. Results of statistical analyses revealed that mafic and ultramafic rocks are the main sources of metal contamination in drinking water, especially Ni and Cr. Both Ni and Cr have toxic health effects and therefore this study suggests that contaminated sites should be avoided or treated for drinking and domestic purposes.

AbstractIn this study, hydrogeochemical processes controlling groundwater chemistry and groundwater quality were investigated. Drinking water is supplied from groundwater (mostly spring and well water) in the study area. The various parameters such as physicochemical parameters, major ions, trace elements and nitrogen derivatives of groundwater samples of were analyzed. These analysis results are compared with drinking water standards for suitability and it does not exceed the permissible limit values, except for the As and F contents of some samples. The results of major ion chemistry of groundwater in the Yalvaç–Gelendost basin suggest that the silicate weathering and ion exchange are the main controlling hydrogeochemical processes in the variation of groundwater quality. The water types are Ca–Mg–HCO3, Mg–Ca–HCO3 and Ca–HCO3 in the basin.Non-carcinogenic health risk assessment associated with arsenic, nitrate and fluoride was assessed by oral (ingestion) and dermal pathways for adult and child. For child, hazard coefficient and hazard index values are less than 1, and a negative effect on usage as drinking water and dermal (skin contact) absorption not expected. But, potential non-carcinogenic effect with oral intake is likely to occur for some water samples for adults. In addition, carcinogenic risk of As element was evaluated for adults and child related to oral and dermal effect. The carcinogenic risk of As through oral intake may pose health risks for children. For adults, it has been determined that water ingestion with dermal exposure may cause cancer. Arsenic is the main toxic element for human health in the study area. The content of As decreases in seasonal water samples. In this case, the negative effect of arsenic intake with ingestion and dermal pathways on health decreases.
