Abstract

This study was conducted at open sewerage in the east campus of the De La Salle University-Dasmariñas. The presence of Escherichia coli and other coli forms was determined to indicate whether the open sewerage of the institution was polluted. The total population of bacteria was measured to ascertain which among the sampling stations had the highest extent of pollution. A survey was also conducted to identify the coliforms and other gram-negative rods included within the sampling areas. Findings revealed that the open sewerage of De La Salle University-Dasmariñas is polluted; Station 1, College of Arts and Sciences, was found to be the most polluted sampling site followed by Station 2 ( Small Business Center Canteen) and Station 3 (Aklatang Emilio Aguinaldo) as revealed by the total microbial count; seventeen (17) gram-negative, faculatively anaerobic rods were successfully identified, eight of which were distinct.
