Throughout the summer season of 2000 samples of acid mine drainage (AMD) were collected from areas below tailing deposits from the coal mining in Svalbard, Norwegian Arctic. The water was analysed for pH, oxygen, conductivity, 9 sulfate and various metals. Oxygen, pH and conductivity were measured by standard electrodes, sulphate was determined gravimetrically and metals were determined by flame/graphite furnace AAS. The AMD was found to contain heavy metals and sulphate in high concentrations, causing damage to the local tundra vegetation. Large spatial variation however was observed in pH (2.5-9.5) as well as in metal concentrations in the AMD, indicating strongly inhomogeneous distribution of sulphide minerais in the tailing deposits.
