For my project, I will use chlorine, and boiling water for ten minutes, to kill coli form bacteria.
I will put feline feces in a bucket for a period of five days with water at room temperature [68 degrees F. to 72 degrees F.]. Next I will attempt to purify the water with the two prelisted methods. Then I will test those samples for waterborne coli forms bacteria, like E. coli., with waterborne test kits. With the data collected from the tests I will be able to determine if all the bacterium are eliminated within the range of the test kits.
Chlorine kills the bacteria by destroying their cell walls. Boiling the water places the cells at a temperature too high for their bodily functions and kills them.
I decided to do this project because I find bacteria interesting because I think that it is intriguing that there is something there but are invisible to our human eye.
My goal for these experiments is to determine if bacteria in water can be eliminated within the range of the test kits by the following methods of water purification of waterborne bacterium:
Chlorine
Boiling water for ten minutes
My hypothesis is that the methods will work because pool owners use chlorine in their pools, and the Chlorine Chemistry Council stated that : "Micro organisms that cause life-threatening waterborne diseases such as cholera, typhoid and dysentery often find their way into water supply systems. Diseases associated with dirty water kill more than 25, 000 people per day -- more than 9 million each year -- around the world, according to the World Health Organization. Since 1908, however, when chlorine was first used in New Jersey to purify water, such epidemic diseases have been virtually wiped out in the U.S. and Canada."
I predict that the boiling will work because in the past I have seen the news on the television suggested sanitizing infected tap water this way.
