This document summarizes investigations of the effluent discharge from a nearby pulp mill into Coos Bay. It discusses discovery of the discharge, but focuses on its effects on gaper clams in the bay.
PART I. A chemical examination of the materials toxic to fish in
kraft pulp mill wastes has been made as part of a water pollution
study. Thirty gallons of "foul condensate" from a typical kraft mill
gave 14 g of organic material when extracted with methylene chloride,
and an additional...
This thesis reports the results of a study on the influence of biologically
stabilized kraft mill effluent (SKME) on the food relations and
production of juvenile chinook salmon, Oncorhynchus tschawytscha
(Walbaum), in laboratory streams. Experiments were conducted at
the Oak Creek Fisheries Research Laboratory, Oregon State University,
during 1967 and...
Raw and biologically stabilized Kraft mill effluents were introduced
into laboratory artificial streams at a ratio of 15 ml per liter
of water over a two year period. Effluent from the stabilization pond
of a second mill was introduced at concentrations of from 5 to 40 ml
per liter of...
A study was conducted to determine the quantity and distribution
of bark debris resulting from log rafting. Three distinct problems were
studied: (I) the quantity of bark dislodged from the logs while being
placed in the rivers and during transport in log rafts; (2) the percentage
of the bark that...
