Abstract
More than sixty inorganic parameters were monitored in the Ter and Llobregat Drinking Water Treatment Plants (DWTPs) using ICP‐MS. Both DWTPs supply approximately four million inhabitants with water in Barcelona and neighbouring areas (NE Spain). The profile of inorganic parameters throughout the treatment process is similar in the Ter and Llobregat DWTPs. Sodium, K, Mg, Ca, Si, Cl‐, SO4 ‐2, Li, Rb, Cs (only in the case of the Llobregat DWTP), Sr, Ba, B, Ti, Cr, V, Co, Ni, Zn, Cu, Sb, Mo, Pb and U were not removed from raw water. Consequently, no improvement was shown as regards the high salinity of Llobregat raw water which is related to the mining activities on the large salt deposits located in the upper part of the basin. However, P, Fe, Mn, Cu and As were removed during treatment. The results obtained reveal the suitability of ICP‐MS for inorganic water quality monitoring in DWTP.Keywords
