The geochemistry of groundwaters from the Meghna River Delta of Bangladesh was studied to determine the distribution of arsenic, and to evaluate the potential mobility of As from the host sediments to the groundwater. Groundwaters from tube wells are characterized by pH of 6.5 to 7.5, oxidation reduction potential (ORP) of +52 to -2 mV, Ca contents of 7 to 25 mg/l, and Fe contents of 0.01 to 22.2 mg/l. Arsenic concentrations ranged from 6 to 934 mu g/l, with an average value of 347 mu g/l. A moderate positive correlation exists between As and Fe (r(2)=0.514; p
