Abstract
Modifications to a standard biological water quality assessment method, used in Belgium since 1979, were studied.
As a result, we recommend the following:
- samples should be processed live
- samples should not be washed through a series of sieves
- systematic units represented by only one individual should be included in the calculation of the biotic index.
Using this modification, the biotic index can be calculated more rapidly and shows a higher correlation with a chemical water quality assessment index.
