Contamination by arsenic and other trace elements in tube well water in Prey Veng and Kandal Provinces, Cambodia
Twenty-eight tube well samples were collected in February, 2006 in the Prey Veng and the Kandal provinces, Cambodia to determine arsenic and its speciation as well as other trace elements. Concentrations of total arsenic ranged from not detectable (ND) to 907ppb, with 54％ of all samples collected exceeding WHO drinking water guideline (10ppb). In addition, 28.57％ of all samples contained concentrations of Mn exceeding WHO drinking water guideline (400pbb). Ba and Sr were also detected with their high concentrations in most of groundwater taken. The distribution of high arsenic concentration was found along the Mekong River with the average well depth at 47m and with recent alluvium sediments. 80％ of tube wells detected with As contamination predominantly existed in soluble arsenite (As (III)) form. The heavy polluted groundwater As was found in the Kandal Province ranging from 21-907ppb.
