5.1 Practical Applications
Using this research, we will be able to do a proper analysis of each plant and what role in can play in Phytoremediation. With that information, we could create new, more efficient and environmentally-friendly water purifiers. We could study how each plant can extract the specific pollutants from each water sample and purify it, making it safer to consume and add those features into the water purifier.
We could also isolate certain plants and plant them in polluted areas to remove the pollutants present thus cleaning the area. For example, Indian Mustard is great at removing heavy metals in a plot of land and therefore can be used in areas which are known to have an excess of heavy metals.

5.2 Areas for further study
We could continue this experiment but on a bigger scale.With more tanks, time and parametres to test, our data would be more accurate.We could also test other plants for their purifying properties and test for more parameters for a more extensive analysis on each plant.
After that in depth analysis of each plant we can figure what role it plays in Phytoremediation, which is a current topic of research, and how it can clean the world’s water. After all, every day, 2 million tons of sewage, industrial and agricultural waste is discharged into the world’s water.  In developing countries, water pollution accounts for close to 14 000 deaths per day due to consumption of water contaminated by raw sewage. The effects of water pollution are far outreaching not only having implications on health, but also disruption of aquatic ecosystems. Therefore, these water purifiers could have a huge impact on the world’s water, turning it into safe, drinkable water for us to use and consume.

5.3 Comparisons with previous research

We had previously done research on Phytoremediation as it was very similar to what we were studying in this ISS project. Phytoremediation is the direct use of living green plants for in place removal, degradation or containment of contaminants in soils, sludges, sediments, surface water and groundwater.(UNEP, 2017) This works because plants are built to adapt to harsh environments and so plants have evolved a great diversity of genetic adaptations to handle accumulated pollutants that occur in the environment such as metals, pesticides, solvents, explosives and crude oil(Voegele, E, 2013). Growing, or in some cases, harvesting specific plants on certain contaminated sites as a remediation method is a passive technique that can be used to clean up sites with shallow, low to moderate levels of contaminants(UNEP, 2017). This type of research is what we are working towards with our project but specifically with water hyacinths and its effects.
