Water Analysis of School Canals along Muralla Street

This study analyzed the physical and bacterial composition of canals on Muralla Street in Intramuros, Manila. Canals samples were collected from five schools: Colegio de San Juan de Letran (CSJL), Lyceum of the Philippines University (LPU), Mapua University (MU), Pamantasan ng Lungsod ng Maynila (PLM), and Manila High School (MHS). Physical properties were analyzed following the APHA 1985 methods used in Okechukwu and Obire's study. Bacterial enumeration used serial dilution and spread plate techniques to obtain the total viable count (TVC). Analysis of Variance (ANOVA) was used to discover similarities and differences in water canal conditions between the studied locations. Results showed significant differences in pH and Dissolved Oxygen (DO) levels, with Letran-Manila exhibiting the highest water quality. However, Total Suspended Solids (TSS) showed no significant difference, suggesting consistent water quality in suspended solids across locations, likely due to similar factors. Bacterial contamination also varied, with PLM showing the highest bacterial counts.
