Throughout the day, lots of water is consumed without thinking of all the bacteria that could be in the water. Most would believe that purified bottled water would be the best choice. Are people really taking the time that they need to make sure all the harmful substances that might be in the water are gone? E-coli is one of many harmful bacteria in water, therefore, the testing for the presence of E. coli in different water samples was performed.
In this project, water samples gathered from water fountains around the school and two water bottle brands were tested. Coliform cult tests were performed, testing for E. coli in the water. Also, water test strips were used to test for total alkalinity, free chlorine, pH, total hardness (amount of calcium carbonate), total chlorine, cyanuric acid, nitrate, nitrite, and bromine. The results came back to be negative for the presence of E. coli in bottled water and school water fountain samples. Also, the 9-way water test strip results for the school fountains were normal for all tests except for pH and chlorine levels. The pH levels were 6.0 in all the school fountain samples, this is considered very low. The chlorine levels were 50 mg/L, however, according to Wikipedia, “chlorine is a highly efficient disinfectant...to kill disease-causing pathogens, such as disease, viruses, and protozoans.” The results …show more content…
coli in drinking water is not something that is typically the topic of conversation, but it is something that is important to health and the environment’s safety. The contamination of drinking water can cause many illnesses with even more gruesome symptoms. The effect of E. coli in natural environments can cause places to be closed. The testing of E. coli isn’t a very hard process and can save the life of a friend or a fish. No matter where the contamination has happened, someone will suffer because it is there, and that is why it was decided to test the main points of water intake in the
