Abstract |
Hydrometric, bacteriological, chemical, plankton, and bottom sediment studies were made of the Scioto River for 115 river miles below Columbus, Ohio, during a period of 30 months, involving three types of sewage treatment at Columbus, the point of heaviest pollution of the Scioto. Times of flow were determined for the stretch of river between Shadeville and Red Bridge 8 and 25 miles, respectively, below the point of entrance of Columbus sewage effluent. The bacteriological and chemical data were grouped according to three temperature and five discharge ranges. A careful examination of the physical properties and biological content of such sediments gives a reasonably accurate picture of average stream conditions. (Author Modified Abstract) |
