Forkortet: The Pasvik groundwater-monitoring project started with the establishment of three monitoring stations in Skjellbekken, Svanvik and Karpdalen at the end of September 2003. Skjellbekken station is about 30 km Southwest of Nikel, Svanvik is about 7 km west of Nikel while the Karpdalen is about 25 km NNE of Nikel. All three wells are established in quaternary desposits and are equipped with PEH casing suitable for groundwater chemistry monitoring. A total of three samples were collected from each station between October and December 2003. The samples were analysed for cation concentrations by inductively coupled plasma-atomic emission spectrometry (ICP-AES: Si, Fe, Ti, Mg, Ca, Na, K, Mn, P, Cu, Zn, V, Ba, Sr, Ag, Sc, Y), heavy metals and trace elements by inductively coupled plasma.mass spectrometry (ICP-MS: Al, B, Be, Cd, Co, Cr, Li, Mo, Ni, Pb, Rb, La, Ce, Zr), anionsby ion chromatography (IC: Br, Cl, F, No3, No2 Po4, So4), alkalinity, pH, turbidity, and colour. The analysis results canb e considred reliable since the ionic charge balance is below 5% for all analyses. The data set is still too small to make any meaningful interpretations and conclusions from the analytical results....
