Earlier studies on runoff water from roads and tunnels have demonstrated that such water hold toxic substances that can be harmful to aquatic biota. River Årungselva, which flows into the inner part of Bunnefjorden close to Oslo, Norway, receives discharges from the Vassum sedimentation pond, which in turn receives tunnel wash water irregularly from three tunnels: Nordby, Smiehagen, and Vassum. The main function of the sedimentation pond is to remove contaminants from the tunnel wash water through sedimentation processes before it flows into Årungselva. Earlier studies have revealed that the growth and survival of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) from Årungselva are lower below the outlet point of the Vassum sedi...
