<![CDATA[Safe urban water supply is influenced by water facility conditions, local geohydrological characteristics, and spatial variation in physicochemical parameters. This study evaluated the spatial quality of clean water facilities in Bengkulu City using field data from 130 observation points consisting of bore wells, dug wells, piped water or PDAM connections, and other community water sources. The study applied a descriptive quantitative approach supported by spatial interpretation. Physical parameters included turbidity indication, odor, taste, and color, while chemical and supporting parameters included Total Dissolved Solids (TDS), pH, temperature, coordinates, and elevation. Data were cleaned, normalized, classified, and assessed using a blackbox rule-based compliance test referring to operational criteria derived from Indonesian clean water quality standards. The results showed that most samples had acceptable organoleptic characteristics, with 122 points not turbid, 129 odorless, 125 tasteless, and 128 colorless. TDS complied at 116 points (89.2%), whereas pH showed the weakest compliance, with only 69 points (53.1%) within the 6.5-8.5 range. Spatial screening identified 63 points as low priority, 47 as moderate priority requiring verification, and 20 as high priority requiring intervention. The findings indicate that basic water quality in Bengkulu City is generally acceptable for several field indicators, but acidity and several spatially clustered risks require further verification, laboratory testing, and location-specific water sanitation management.]]>
