EFFECTS OF WASTE ON WATER QUALITY AND USES
RIVER SURVEY, 1964
Early in 1964, Mr. Robert McHugh of the Oregon State Sanitary Authority had completed translation of German literature relating to similar slime problems (16). The German...

the higher-velocity layers. The net...

The intermittent waste discharge from Camas causes a change in water quality and in river conditions that can be traced with water quality tests (12), and these tests have confirmed calculated river flow data. Each fisherman's report was reviewed...

REDUCTION OF FIBER AND BOD LOADINGS
Two constituents present in pulp and paper manufacturing wastes discharged to the Columbia River contribute to the slime problem in the stream. Evidence indicates that slimes develop on suspended fiber...
