Arsenic, one of the most poisonous chemical elements, was analyzed in the waters of the host of the 2010 Commonwealth Games, i.e., New Delhi. The study revealed shocking outcomes with arsenic concentrations well beyond the safe limits set by WHO, and a maximum concentration up to 180 ppb was found in the groundwater. Analysis of around 120 water samples collected extensively along the Yamuna Flood Plain showed that more than 55% had arsenic contamination beyond the WHO limit of 10 ppb. The maximum value of arsenic in coal and fly ash from Rajghat coal-based thermal power plant contained 200 and 3,200 ppb, respectively. Moreover, the ore petrography of coal samples shows the presence of arsenopyrite mineral. Maximum concentration of arsenic contamination is found within a 5-km radius from power plants. In the perspective of Delhi, arsenic contamination is purely anthropogenic due to coal-based thermal power plants, which had already shown toxic arsenic, fluorine and China-type coal effects. The presence of such power plants in coal field locations, e.g., West Bengal and Bangladesh, could release the arsenic due to combustion in superthermal power plants, thus accentuating the arsenic concentration besides the natural arsenic coming from the foreland basins of the Himalaya in Indian sub-continent.Keywords Arsenic Á Water Á Coal and fly ash Á Coal-based thermal power plant Á Delhi

“…Currently, arsenic is estimated to affect more than 150 million people worldwide with its increasingly elevated concentrations in drinking water [39]. The major areas affected by arsenicosis have been reported to be large deltas and/or areas along major river basins across the world [40], such as in the Paraiba do Sul delta, Brazil [41], the Bengal delta [42][43][44], the Mekong delta, Cambodia [45], the Danube River basin, Hungary [46], the Hetao River basin, Mongolia [47], the Duero Cenozoic Basin, Spain [48], the Zenne River basin, Belgium [46], and Tulare Lake, USA [49]. The transfer of arsenic into the food chain will ultimately continue as a long-term risk to human and ecological systems [50].…”

The functional polymer materials have presented a great development in adsorption processes for the treatment of polluted waters. The aim of the current review is to present the developments during the few last years in this field of study by examining research of systems like water-functional soluble polymers and electro-oxidation process coupled to ultrafiltration membranes for decontamination processes in liquid-liquid phase. The study is addressed to arsenic which is considered one of the most hazardous contaminants.

“…High arsenic (As) concentrations in domestic bedrock wells have emerged as a public health concern in Africa (Kortatsi, 2007; Smedley, 1996; Smedley et al, 2007), Asia (Ahn, 2012; Shukla et al, 2010), Europe (Aloupi et al, 2009; Heinrichs and Udluft, 1999), and Central and North America (Armienta et al, 2001; Ayotte et al, 2003; Boyle et al, 1998; Colman, 2011; Kim et al, 2011; Lipfert et al, 2006; Peters and Blum, 2003; Peters and Burkert, 2008; Pippin et al, 2006; Ryan et al, 2011; Yang et al, 2009), especially in rural areas without public water supply. These bedrock wells typically have low yields and supply small communities or individual households (Drew et al, 2001).…”

To understand the hydrogeochemical processes regulating well water arsenic (As) evolution in fractured bedrock aquifers, three domestic wells with [As] up to 478 µg/L are investigated in central Maine. Geophysical logging reveals that fractures near the borehole bottom contribute 70–100% of flow. Borehole and fracture water samples from various depths show significant proportions of As (up to 69%) and Fe (93–99%) in particulates (>0.45 µm). These particulates and those settled after a 16-day batch experiment contain 560–13,000 mg/kg of As and 14–35% weight/weight of Fe. As/Fe ratios (2.5–20 mmole/mole) and As partitioning ratios (adsorbed/dissolved [As], 20,000–100,000 L/kg) suggest that As is sorbed onto amorphous hydrous ferric oxides. Newly drilled cores also show enrichment of As (up to 1,300 mg/kg) sorbed onto secondary iron minerals on the fracture surfaces. Pumping at high flow rates induces large decreases in particulate As and Fe, a moderate increase in dissolved [As] and As(III)/As ratio, while little change in major ion chemistry. The δD and δ18O are similar for the borehole and fracture waters, suggesting a same source of recharge from atmospheric precipitation. Results support a conceptual model invoking flow and sorption controls on groundwater [As] in fractured bedrock aquifers whereby oxygen infiltration promotes oxidation of As-bearing sulfides at shallower depths in the oxic portion of the flow path releasing As and Fe; followed by Fe oxidation to form Fe oxyhydroxide particulates, which are transported in fractures and sorb As along the flow path until intercepted by boreholes. In the anoxic portions of the flow path, reductive dissolution of As-sorbed iron particulates could re-mobilize As. For exposure assessment, we recommend sampling of groundwater without filtration to obtain total As concentration in groundwater.
