A study was made of the stump washer effluent, and the main outfall and the various components that make up the plant effluent. Gulf Naval Stores Company operates 12 extractors to produce FF wood rosin, turpentine, pine oil and dipentent. The survey was conducted to determine the quantities and characteristics of process wastes resulting from the operation of a naval stores plant. Results of this work and similar studies will serve as basis for preparation of an industrial waste guide on naval stores wastes.
