The object of this project was to determine if boiling water for ten minutes and the use of chlorine would kill coli forms to a safe level. I grew a culture of bacteria with feline feces and water then tested it for the presence of living bacteria. Then, I treated samples of the water with boiling for ten minutes and adding chlorine. After that, I tested the samples and found no living coli forms.

The results of this experiment supports my hypothesis because my hypothesis stated that all methods of sanitation will kill the coli forms to a level considered safe for consumption and the results showed that both methods, boiling for ten minutes and the use of chlorine, killed the coli forms to a level considered safe for consumption.

 

The results of the first test showed that there were coli forms present in the water so that the rest of the project could be continued: the sanitation of the water by both methods and then the testing of the sanitized samples. The other two tests showed that the two methods did indeed kill the coli forms to a level considered safe for consumption.
