Atwood, Judith Elaine
MetadataShow full item record
This project was undertaken to determine the condition of a river by using both physical and biological data. Through combining chemical testing and a survey of the bottom invertebrates, it was hoped the biological community and the causes for that particular community could be determined, along with obtaining information about pollution indicator species. Testing of the method, as well as obtaining results, was a primary objective.
