High levels of uranium in groundwater of Ulaanbaatar, Mongolia

Water samples collected from 129 wells in seven of the nine sub-divisions of Ulaanbaatar were analyzed by inductively coupled plasma mass spectrometry (ICP–MS) using Clean Lab methods. The levels of many trace elements were found to be low with the average concentrations. The levels of uranium were surprisingly elevated (mean, 4.6 μg/L; range < 0.01–57 μg/L), with the values for many samples exceeding the World Health Organization's guideline of 15 μg/L for uranium in drinking water. Local rocks and soils appear to be the natural source of the uranium.
