Abstract

Drinking water fountains are one of the primary sources of drinking water for the public, particularly in places like schools. This widespread use brings up concerns about the sanitation and cleanliness of water consumed by students. This study aims to evaluate the physico-chemical and microbiological quality of water from selected drinking fountains at De La Salle Medical and Health Sciences Institute (DLSMHSI), following the Philippine National Standards for Drinking Water (PNSDW), to ensure that the drinking water quality in the educational institution is safe for health. Water samples from five fountains were analyzed. Physico-chemical tests, including odor, chlorine residual, and pH levels, were conducted by Dasmariñas Water District. Microbiological analysis was performed at DLSMHSI’s Angelo King Building using serial dilutions and spread plate techniques. All physicochemical parameters met the 2017 PNSDW guidelines. All fountains have identical results of a chlorine residual less than 0.30 mg/L, unobjectionable odor, and pH value of 7.8. The microbial testing resulted in most of the samples being TFTC with the exceptions of 143, 48, 49, 45, and two TNTC. The elevated microbial counts were likely due to inadequate equipment sterilization or poor sample handling. To conclude these findings, the water quality in all drinking fountains is deemed safe for consumption. The research suggests expanding future studies to include samples from different areas to understand water quality variations better. It also recommends analyzing the impact of environmental and infrastructural factors, and testing for microbiological bacteria to ensure water meets public health standards.
