UNDALOS, LEI B. Microbiological and Physico-chemical Analyses of Water in Selected Areas of Labac River. Undergraduate thesis, Bachelor of Science In Biology, Department of Biological Sciences, College of Arts and Sciences, Cavite State University, Indang, Cavite. Adviser: Prof. Michele T. Bono This study aimed to determine the microbiological quality and physico-chemical characteristics of water in selected areas of Labac river. Three sampling sites were chosen: recreational, residential and agricultural. Total and fecal coliform counts were determined for the microbiological quality and pH, dissolved oxygen (DO), total dissolved solids (TDS), and biological oxygen demand (BOD) for the physico-chemical characteristics.
Total coliform (TC) count on water samples from e three rivers ranged from 170MPN/100mL to 2,400MPN/100mL. Balsahan River had the highest TC count but did not exceed the standard set by DENR. Meanwhile, fecal coliform count (FC) ranged from 190MPN/100mL to 2,400MPN/100mL wherein values from Balsahan River and Convento River exceeded the DENR standard. Sixty-nine (69) isolates were presumptively identified to be under nine genera namely Escherichia, Citrobacter, Edwardsiella, Serratia, Salmonella, Kluyvera, Enterobacter, Shigella and Pseudomonas. pH, dissolved oxygen (DO), total dissolved solids (TDS), and biological oxygen demand (BOD) of Convento River and Banaba River were within the standard limit sel by the DENR. Dissolved oxygen (DO) of Balsahan River was also within the DEN standard but p1-1, TDS and BOD exceeded the standard limit. Moreover, TC and FI counts ad significant relations p with pH. BOD and TDS and no significant relationship with DO.
