INTRODUCTION Significance of the Study With two-thirds of the earth’s surface covered by water and human body consisting of 78% of it. It is evidently clear that water is one of the prime elements responsible for life on earth. It is necessary for the digestion and absorption of food, help maintain proper muscle tone and supply oxygen and nutrients to cell (Quiles and Quiles, 1996). A drinking water is defined as water intended primarily for human consumption but which has another domestic purposes. It may consume directly from the tap for beverages and food prepared with water. But according to Hippocrates, water supplies may also be contaminated with organisms that can cause disease. Among diseases that may transmitted by water…show more content…
And according to the result (Appendix A,B and C), the three sources of drinking water are microbiologically contaminated. Drinking water should be safe to use. A clean drinking water can reduce the number of waterborne disease. It can be clean through water treatment. And one way of treating drinking water is a Solar Water Disinfection (SODIS) method. SODIS is a low-cost method of water treatment that can be implemented with locally available materials and environmentally friendly. This method can easily use by individuals because of its simple procedures. It is viable option especially for individuals with insufficient income to buy bottles water and avail of house connection. This study will be beneficial to the residents of Purok Cueva since it can help to treat their contaminated drinking water with a method that is simple and inexpensive. Objective of the Study The main purpose of the study is to use SODIS as a method for treating water at Purok Cueva. Specifically this study aims to determine: a.) The population of coliform bacteria before the application of SODIS method; b.) The population of coliform bacteria after the application of SODIS method; c.) The percentage removed of coliform bacteria; and d.) If SODIS can be used a water treatment method at Purok Cueva. Scope and Limitation of the Study This study is only limited to determine the percentage removed and the population of the coliform bacteria
