Water Quality

A Reference to review plans by the State of Vermont to modernize the Alburg-Swanton Bridge, involving the partial removal of the existing causeway, and to provide advice on whether this complies with the terms of the Boundary Waters Treaty of 1909 as concerns causing pollution to the injury of health or property in Canada or the United States.

The IJC recommended that additional steps should be taken immediately to accelerate the reduction of phosphorous pollution in the Missisquoi Bay. Although the IJC recognized that the removal of the causeway would have a negligible impact on phosphorus levels in the bay, it recommended the removal of the causeway because its presence was viewed as a serious impediment to progress and phosphorous reduction.
