Physico-Chemical and Microbiological Assessment of Domestic Water Samples in Barangay Ferdinand, Marcos, Ilocos Norte

This study aimed to assess the physico-chemical and microbiological quality of water samples in Barangay Ferdinand, Marcos, Ilocos Norte, to provide a basis for future water quality improvement initiatives. The study involved the collection and analysis of water samples from different household sources such as deep wells and developed springs. Standard procedures and testing methods were employed to evaluate the physico-chemical parameters, including pH level, temperature, turbidity, total dissolved solids (TDS), and presence of nitrates, as well as microbiological parameters specifically focused on total coliform and E. coli presence. Results revealed that most of the water samples met the acceptable standards for pH and temperature as set by the Philippine National Standards for Drinking Water (PNSDW), some samples exhibited elevated turbidity and TDS levels, indicating possible contamination from environmental runoff or improper maintenance. Microbiological analysis indicated the presence of total coliforms in a significant number of samples, and E. coli in selected locations, highlighting potential health risks from fecal contamination. The findings underscore the importance of regular water quality monitoring and the implementation of community-level water treatment or sanitation practices. The study recommends awareness campaigns, proper sanitation infrastructure, and localized water treatment solutions to mitigate contamination risks.
