For more than 25 years water quality of the Lower Columbia River has been adversely affected by abundant slime growths which flourish periodically. Materials contained in wastes from seven pulp and paper mills supply the nutrients for slime growth. Commerical fishermen's nets become coated with slime; fibers in the slime become entangled in the knots of the nets, making slime removal extremely difficult. Sport fishing and other forms of water-contact recreation have also been adversely affected by the slime gorwths. A waste control and treatment program for pulp and paper wastes discharged to the Columbia River is reasonable and attainable.
