Physical and chemical property analysis of tap water in Cantilan, Surigao Del Sur

Abstract

Safe and potable water is crucial to ensure public health. This study evaluates the physical and chemical properties of tap water sources in Cantilan, Surigao del Sur, a town known as the “Cradle of All Towns.” Water samples from multiple locations were analyzed to determine compliance with the Philippine National Standards for Drinking Water (PNSDW) 2017. The physical and chemical tests assessed parameters such as pH, turbidity, total dissolved solids, and heavy metal concentrations.  Results showed that parameters such as pH, turbidity, total dissolved solids, and heavy metal concentrations consistently fell within acceptable limits, ensuring the safety and palatability of the water. While nitrate levels and total hardness remained within permissible thresholds, year-on-year fluctuations in certain parameters highlight the importance of continued surveillance to maintain water quality. Overall, the findings confirm that the water sources in Cantilan are safe but ongoing maintenance and periodic evaluations are recommended to ensure sustained compliance and public health protection.
