Abstract

Ninety eight drinking groundwater samples collected from different depths of Cox's Bazar paleo-beach and the hills behind the beach were analyzed using ICP-MS for contents of U and Th together with minor and major chemical components. About 4% of studied shallow tubewells (<30m in depth) contained excess U from the WHO drinking water guideline, 2.0 ug/l, which were mainly found at paleo-beach sites.
