It is a simple method that permits one to gain a clear insight into the ecological quality of water courses with very limited means. Biological water quality assessment is a valuable supplement to chemical water quality assessment systems, scientifically as well as educationally. The Belgian variant (Belgian Biotic Index, BBI) was set and repeatedly tested by a cooperation of several laboratories. Since 1984 it is the offical standard method for biological water quality assessment in Belgium. This BBI has proven to be much more applicable, with slight adaptations, than merely in Belgium, at least all over Europe. Concerning application at the secondary education level the BBI has one big advantage compared to other methods (standardized elsewhere in Europe): the assessment of the biotic index is quick, easy and requires no work for a specialist or big investments. In the educational field the BI integrates in an active way (field work) the biology lessons of classifications and ecology: the determination of the macro invertebrates is based on the principles of the biological classification system and its interpretation in terms of water quality is connected with human influences on the environment. When the assessment of the biotic index is combined with chemical water analyses, clear conclusions can (mostly) be drawn concerning the cause of the pollution and thus we have an integration of the biology and chemistry lessons.
