5.1 Practical Applications
People can use the water hyacinth as a bioindicator to tell if there is any pollutants in the water or not. If the water hyacinth dies there are pollutants in the water, however, if the water hyacinth remains alive the water is clean.
5.2 Areas for further study
Further studies can be conducted to see if which oil, bacteria or sand affect the water hyacinth.
