“…High P concentrations up to 3.54 mg L À1 have also been observed in groundwater from the Hetao Basin (Guo et al, 2008). This competition phenomenon has been reported previously at La Pampa and Santiago del Estero in Argentina and at Kandal in Cambodia on agricultural lands with extensive phosphate fertilizer applications Bhattacharya et al, 2006;Rowland et al, 2008). The high loadings on Fe in PC4 could be attributed to the drainage derived from mining activities (Palma et al, 2010).…”

“…According to another study, where arsenic concentration in groundwaters of Northern Greece was investigated, this value is realistic and actually is at the lower end of values measured in the arsenic affected ground waters in this region [5]. Values of alkalinity ranged between 4 and 8 mM HCO 3 in this area, and similar or slightly higher concentrations were measured in other areas with arsenic polluted groundwaters, such as in Argentina [24], in the Pannonian basin [25], and in Pakistan [26]. Therefore, since alkalinity is known to affect the efficiency of coagulation, in the present study, alkalinity values from 1 to 8 mM were examined to evaluate the effect on As(III) removal.…”

“…In recent years various studies have highlighted that countries such as Argentina, Bangladesh and Chile were experiencing high total concentrations of natural and anthropogenic (man-made) arsenic in drinking water from newly identified sources (Halim et al 2009;Bhattacharya et al 2006;Oyarzun et al 2004;Ng et al 2003;. The most common sources of arsenic in the natural environment are volcanic rocks (specifically their weathering products and ash), marine sedimentary rocks, hydrothermal ore deposits and associated geothermal waters, and fossil fuels, including coals and petroleum (Wang and Mulligan 2006;Smedley and Kinniburgh 2002).…”
