“…In accordance with what several authors have previously reported (Fritzsche et al, 2011;Gan et al, 2014;García-Sánchez et al, 2010;Makris et al, 2009;Ravenscroft et al, 2005;Sahu et al, 2011;Smedley and Kinniburgh, 2002;Wey et al, 2006), this may be explained by As being frequently associated with Fe and Al compounds. Thus, higher Fe-Al content in the soil may be responsible for increase of As sorption in soil.…”

“…Biofilms were further acclimatized for three weeks using the synthetic groundwater amended with 1.0 mM As(III); this would make the chemoautotrophic AOBs enriched in the biofilms. The synthetic groundwater consists of the following components per liter (pH 7.0): 277.50 mg CaCl 2 , 150.00 mg MgSO 4 , 9.00 mg NH 4 Cl, 6.00 mg KNO 3 , 3.16 mg H 3 PO 4 , 1.21 mg SrCl 2 $6H 2 O, 0.02 mg (NH 4 ) 6 Mo 7 O 24 $4H 2 O, 18.00 mg MnCl 2 $4H 2 O, 655.20 mg NaHCO 3 and 2.78 mg FeSO 4 $7H 2 O (Gan et al, 2014). The arsenite-oxidizing ability of the bioreactor was determined by monitoring the concentrations of different arsenic species of the effluent.…”

“…This trend is typical of the depth distributions of As and Fe in other As‐polluted Asian deltas and alluvial settings, for example, the Bengal Basin (Karim, Komori, & Alam, ; Department of Public Health Engineering [DPHE], ; et seq.) and the Jianghan Plain, China (Gan et al, ).…”

Groundwater beneath the alluvial plain of the Indus River, Pakistan, is reported to be widely polluted by arsenic (As) and to adversely affect human health. In 79 groundwaters reported here from the lower Indus River plain in southern Sindh Province, concentrations of As exceeded the WHO guideline value for drinking water of 10 μg/L in 38%, with 22% exceeding 50 μg/L, Pakistan's guideline value. The As pollution is caused by microbially‐mediated reductive dissolution of sedimentary iron oxyhydroxides in anoxic groundwaters; oxic groundwaters contain <10 μg/L of As. In the upper Indus River plain, in Punjab Province, localized As pollution of groundwater occurs by alkali desorption as a consequence of ion exchange in groundwater, possibly supplemented by the use for irrigation of groundwater that has suffered ion exchange in the aquifer and so has values >0 for residual sodium carbonate. In the field area in southern Sindh, concentrations of Mn in groundwater exceed 0.4 mg/L in 11% of groundwaters, with a maximum of 0.7 mg/L, as a result of reduction of sedimentary manganese oxides. Other trace elements pose little or no threat to human health. Salinities in groundwaters range from fresh to saline (electrical conductivity up to 6 mS/cm). High salinities result from local inputs of waste water from unsewered sanitation but mainly from evaporation/evapotranspiration of canal water and groundwater used for irrigation. The process does not concentrate As in the groundwater owing to sorption of As to soils. Ion exchange exerts a control on concentrations of Na, Ca, and B but not directly on As. High values of Cl/Br mass ratios (most ≫288, the marine value) reflect the pervasive influence on groundwater of sewage‐contaminated water from irrigation canals through seepage loss and deep percolation of irrigation water, with additional, well‐specific, contributions from unsewered sanitation.
