Project Details
  • Lausanne Tunnel
    Passive Treatment System
    Lehigh River
    Nesquehoning Creek

    In order to mitigate the impacts of mine drainage on the Lehigh River, this project used the
    existing amount of alkalinity contributed by the Lausanne Tunnel to facilitate the oxidation of
    the heavy metals contained within the discharge. The water is naturally aerated and it has been
    directed into a 1.5-acre manmade wetland complex, constructed at the Lausanne Tunnel outfall.
