Bacteriological assessment of the potable water systems in selected barangays of Capoocan, Leyte Katherine Aprille S. Dula; Irene L. Tan, adviser. 2012. vii, 33 leaves illustrations. Undergraduate thesis (B.S. Biology) -- University of the Philippines, Tacloban. Microbial monitoring of seven water systems in Capoocan, Leyte was done using Multiple Tube Fermentation Technique. Two samples were collected in each sampling site (one from the source and one from the point of use) thrice from the months of January to March. Physico-chemical parameters such as pH, temperature, and residual chlorine of the water samples were determined. A test for taste and odor was also done using a sensory evaluation technique. Total coliform and fecal coliform results obtained were evaluated against standard values for public drinking water supplies. Only the MCWD sampling station was found to be free from total coliform and fecal coliform contamination. All other sites exhibited high MPN/100 ml values for total coliform and fecal coliform. Quality of water supply in many sampling stations is not satisfactory since water samples collected were mostly contaminated with coliform bacteria.
