Water Pollution

Click on Image to Access Publications

 

Biotic Index Card (Penn State Extension)

The Biotic Index was developed by William M. Beck, Jr. in response to the need for a simple biological measure of stream pollution. This method is based on the classification of selected aquatic invertebrates into categories depending on their response to organic pollution (sewage and other oxygen demanding wastes). General experience has indicated that the Biotic Index is also useful in classifying other types of pollution. Extensive study of the distribution of invertebrates in relation to water quality enabled Beck to divide these organisms into three groups on the basis of their ability to tolerate organic pollution.
