A preliminary ICP-MS investigation of potable and treated sewage water (TSW) showed that the rare earths were present at levels up to 20 μg/L in TSW (20 mgper ton of TSW); whilst nothing was detected in the potable water samples. A total of 12 samples were studied and the analytical performance of the ICP-MS system (detection limit 0.001 flg/L for rare earths) produced relative errors of
