To investigate the heavy metal pollution in leachate from sanitary landfill site of municipal solid waste, a survey was conducted in Tromsø, Northern Norway. Results shows that contents of heavy metals in landfill leachate follow the order Mn>Zn>Ni>Cu>Cr>As>Pb>Cd>Hg, and the order of the risk of different heavy metals is: Mn>Ni>As>Zn>Cr>Pb>Cd>Hg>Cu. The concentrations of Mn and Ni in landfill leachate exceeded the standard. Mn had the highest single standard index. it took the highest risk to surround water and environment. According to comprehensive evaluation of water quality, the landfill leachate is moderately polluted. It is helpful for the control and management of leachate in garbage plants to know the degree and types of heavy metal pollution in leachate.
