Water treatment practices related to arsenic removal from water are discussed. Arsenic levels in the Regina/Moose Jaw water distribution system are presented, along with an examination of the factors that may release arsenic held in the sediments in Buffalo Pounds Lake, the source of water supply ...

In Bangladesh and West Bengal, alluvial Ganges aquifers used for public water supply are polluted with naturally occurring arsenic, which adversely affects the health of millions of people. Here we show that the arsenic derives from the reductive dissolution of arsenic-rich iron oxyhydroxides, which...
Part II: Oxidation of Arsenic and its Removal in Water Treatment In natural waters arsenic normally occurs in the oxidation states +III (arsenite) and +V (arsenate). The removal of As(III) is more difficult than the remo... M Bissen,FH Frimmel - 《Clean – Soil Air Water》 被引量:...
south-eastern part of Ghana (Accra, Eastern and Volta regions) revealed low to medium concentrations in the range of 2-39 mg l-1, with only 2% of boreholes tested having arsenic concentration exceeding 10 mg l-1 of the WHO (2004) maximum permissible level of arsenic in drinking water. ...
In groundwater, used for drinking water supply in the greater industrial area of Thessaloniki, in Northern Greece, concentrations of total arsenic exceeded the WHO provisional guideline value and the EU maximum contaminant level (MCL) of 10 μg/L. The concentration of total arsenic was in the ...
