Abstract:

Water is considered as one of the most basic necessities of human beings. As a matter of fact, water is of major importance to all living things. Up to 60% of the human adult body is composed of water-- the brain and the heart are composed of 73 % water. Therefore, the researchers studied the drinking water of Barangay Corona, Municipality of Tingloy. The researchers had chosen multiple tube fermentation techniques as their method for laboratory analysis as it detected coli form bacteria which are a very broad group of bacteria that impose risk to human health. They had chosen 30 different sites from Barangay Corona to examine. The researchers transported the samples, preserved in a cooler with ice. Then, they mixed Lauryl Tryptose Broth with water. If coliform bacteria is present in the water, it will induce fermentation which is concluded by gas formation and cloudy appearance. All 30 sites tested were positive. The researchers gathered some data from the Municipal Health office, and it reaffirmed that the deep wells in Barangay Corona were breeding areas of Coliform Bacteria.
