Conclusion

There are not much difficulties faced during our investigation with the help of the notes on the Home-based Learning site.

In conclusion, we, as a group, feel that the DULL water should not be repurified for sale, not because our methods will not work, but because the water is meant for drinking and something that will be taken into our body, hence, it must be safe. Thus for safety measures, we should not re-purify the contaminated water for sales since the water is already so contaminated and there will most probably be other small pollutants. But this does not mean that all the effort has gone to waste, it can be a learning point for the company to improve its security so that the same kind of incident will not happen again.
