The report concerns an on-going study designed to monitor changes in the saltwater environment and populations of marine organisms in Port Gardner and adjacent waters of Puget Sound, Washington resulting from significant reductions in sulfite waste liquor (SWL) and other wastes discharged from two pulp and paper mills located on the Everett, Washington waterfront. Major reductions in the quantity of wastes discharge occurred in 1975 when Weyerhaeuser Company closed their sulfite pulping operation and converted to a thermomechanical process. Early indications of improvements in water quality were noted as a result of these reductions. SWL concentrations decreased approximately 50% and dissolved oxygen concentrations have increased as much as 30%. Toxicity of the receiving water to Pacific oyster larvae has decreased and the water clarity has increased significantly. Changes in population and diversity of biological organisms were not readily apparent since reductions in major waste discharges have only recently occurred.
