"March 1983." Includes bibliographical references (pages 36-37). "Water quality of the Kootenay River above and below the pulpmill at Skookumchuck was studied from June 1980 to June 1982. The direct discharge of the Skookumchuck pulpmill effluent of the Kootenay River resulted in elevated downstream levels of colour, sodium, chloride, tannins and lignins and phenolic materials. There was a poorly defined sag in dissolved oxygen downstream of the effluent disposal site. Additionally there were chlorinated phenols present in samples collected downstream of the pulpmill that were not found upstream of the pulpmill. The change in effluent disposal practice in December 1981 from direct discharge to the river to the rapid infiltration system has eliminated the downstream effects of the pulpmill"--Abstract.
