"During 1979, the Environmental Protection Service conducted environmental surveys of receiving waters of south coastal pulp mills at Powel River, Crofton, Harmac, and Elk Falls, B. C., in order to assess the effectiveness of environmental controls. Parameters examined in the surveys included water column temperature, salinity, dissolved oxygen, colour, sediment character, and trace metals in the sediments and in animal tissue. In addition, sediment samples were analyzed for particle size and total volatile residues at Powel River, Harmac, and Elk Falls, and trawls were conducted at Powell River and Crofton to determine species diversity. The data is presented, results are discussed, and conclusions are drawn. Surveys at north coastal and interior mills will be reported elsewhere"--Abstract, page i. Issued also in print format.
