I hope all of you have looked at my graphs, some interesting results in there!
I was surprised to see that the chlorine results were negative for all the waters except tap. This shows that a filter decreases the amount of chlorine.
The pH was interesting too. They ranged from 6.4 to 7.4! The healthy state for drinking water is 7.0. None of our waters were exactly that.
Over the weekend I will test the breathing rate of the bacteria.
Please comment and tell me what I can improve on.
