Potable Water Hunt: An Alternative Water Sources Assessment In Selected Areas In Negros Occidental

Discipline: Education

 

Abstract:

This study assessed the suitability of alternative water sources for drinking in selected areas of Negros Occidental. Water samples were collected from two types of sources: a hand-dug well and a borehole hand pump. Researchers evaluated these samples based on microbial and physicochemical parameters and classified them according to the standards set by the Department of Environment and Natural Resources (DENR). Physicochemical analyses took place at the Negros Prawn Producers Cooperative Analytical and Diagnostic Laboratory (NPPC). Meanwhile, microbial analyses were conducted at the NONESCOST laboratory using the standard multiple-tube fermentation technique. Results showed that the alternative water sources in Kabankalan City, Himamaylan City, San Carlos City, Escalante City, and Sagay City had high coliform levels. This indicates that water from these sources is not safe for drinking. Based on physicochemical parameters, these sources were assigned to Class B (Recreational Water, Class I). Microbial analysis categorized them as Class A (Public Water Supply, Class II). In contrast, the alternative water source in La Carlota City produced better results. Its physicochemical parameters mostly met the DENR standards for drinking water, except for chloride and total hardness levels. Despite these minor exceedances, the water source was classified as freshwater under Class AA, which is suitable as a Public Water Supply, Class I, based on microbial indicators. The findings of this study provide crucial baseline information on the quality and safety of alternative water sources in Negros Occidental. This information is particularly useful for local communities and authorities in finding safe drinking water sources during times of insufficient supply and during emergencies or disasters.
