None of the previous animals are used to indicate the quality of water in an area – they are nice to find, but are often the first to go if the water is not good.
Indicators of Water Quality Macroinvertebrates – without backbones, large enough to be seen Many of the macroinvertebrates are insect larvae that spend part of their life cycle as aquatic organism.
The macroinvertebrates are divided into groups based on their tolerance of poor water conditions. Group I– indicators of good water quality. These have low tolerance of pollutants. Group II– indicators of fair water quality. These have moderate tolerance of pollutants. Group III– indicators of poor water quality. These have high tolerance of pollutants and low oxygen levels.
