| Summary | Physical, biological and chemical comparisons of a stream system receiving primary treated sewage effluent and a stream receiving only agricultural run-off were made by determining the relative numbers of pollution tolerant and pollution sensitive macroinvertebrates in each stream system and by using chemical and physical data, a total ecological picture was obtained. Bartsch (1948) and Gaufln and Tarzwell (1952) confirmed the concept of stream ecosystems supporting only certain macroinvertebrate populations under certain conditions of chemical and physical environment. Dredge samples, chemical and physical data were collected semimonthly at several stations on each stream from January to June, 1971. The data showed that the creek polluted by treated sewage was able to recover from this overload within a few miles of the effluent outflow. Agricultural run-off during the latter part of the study caused a noticeable increase in the chemical and biological factors linked with increased pollution levels. This increase was noted in both creeks but the creek lacking sewage effluent reflected the presence of increased run-off to a greater extent since this was the predominant pollution source in the stream system. |
