The Finished Product

Bacteria Testing

Due to lack of time and materials I am unable to conduct this bacteria experiment.

My Science Fair Board

This week I have worked mainly on my board. I've spray-painted it, printed all my information, pictures and graphs, backed it on coloured paper and made my heading. I have just finished working on my board and will post pictures soon.

My Conclusion of my Hypothesis

My hypothesis was proven incorrect and correct at the same time. I estimated that Distilled would be healthier, but H2Go proved that guess wrong. I was correct in the sense that I thought tap would be the worst.

I found this really interesting, because automatically people think that distilled would be healthier, but in actual fact the brand H2Go was healthier by far. In fact, distilled was one of the worse ones.

What was astounding was that our tap water was actually quite bad! Everyone goes to the tap and drinks the fresh water. This also shows that having a filter will make your water a lot healthier. According to my observations, having a filter will not only make it healthier, but it will also take out excess chlorine in your water.

Conclusion

Conclusion of pH and Chlorine Results:

H2Go proved itself the best, while tap proved itself worst. Distilled was the most acidic, with Pump close behind. Tap had the most alkaline. The healthiest of the pH were filtered, H2Go, and surprisingly enough, pond! No one water had a perfect 7.0 pH level. As for the chlorine, things were different. Tap was the only water with a little chlorine. This is good and bad, because water needs a little bit of chlorine to kill off bacteria but it does have a smell and taste. The results state that having a filter will decrease the amount of chlorine in the water that you drink. Pump, H2Go and Distilled went through a scanning system to kill off all bacteria, therefore giving no need for chlorine in those waters. The copper results were fine. Having a very slight amount of copper in your water is fine, but anything over the maximum contaminant level will cause stomach and intestinal sickness. The iron results were fine too. All the iron levels were below the maximum contaminant level.

A Few Facts to Know...

From looking at all my graphs, you probably don't know whether having things like iron in your water is good or bad.

It isn't very good to have iron in your household water, because it gives water some taste and also makes the water stain things.

It isn't a good idea to have too much copper in your water as well, because this can cause stomach and intestinal sickness.

The proper amount of copper and iron is below:

The MCLG level (Maximum Contaminant Level Goal) for copper is 1.3ppm. Copper can enter the water when it is going through the kilometers of metal piping.

The MCLG level for iron is 0.3 to 1ppm. Iron also causes discoloured water and it also doesn't work very well in a filter.

Results

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.

Testing

Over the next few days, I will be experimenting. I will post up interesting information I come across, as well as a few results.

Take a look at my method, and be sure to post up some comments about suggestions, questions, feedback, and more.
