The lists of algae in the tables are meant to be aids for persons engaged in 

 stream pollution surveys or related projects. They give a general consensus 

 of opinion as to the relative significance of the many algae tolerant of organic 

 wastes which have been reported. Particular care can thus be taken in bio- 

 logical surveys to check for the presence of these genera and species of algae 

 during the microscopic examination of samples. 



The references given represent many of the more exhaustive studies that were 

 included in the preparation of this report.
