<![CDATA[The growing demand for drinking water driven by population increase requires not only sufficient supply but also assurance of water quality for safe consumption. In Wringinpitu Village, Banyuwangi Regency, groundwater from bore wells serves as a primary drinking water source due to limited piped water coverage. This study evaluates the feasibility of bore well water using the Drinking Water Quality Index (DWQI), integrating physical, chemical, and biological parameters into a single representative value. Water samples were collected from two bore wells and analyzed based on the Indonesian drinking water standard (Ministry of Health Regulation No. 2 of 2023). The results indicate that most parameters, including odor, color, turbidity, iron (Fe), pH, nitrate, nitrite, and microbiological indicators, comply with the established standards. However, Total Dissolved Solids (TDS) and Manganese (Mn) require particular attention. TDS concentrations reached 585 mg/L (SB-01) and 1091 mg/L (SB-02), exceeding the allowable limit of 300 mg/L, while Mn levels were 0.1 mg/L and 0.135 mg/L, respectively. Elevated TDS levels are likely influenced by the hydrogeological setting, particularly the proximity to coastal areas, which contributes to higher mineral content in groundwater. Meanwhile, Mn presence is associated with aquifer geochemistry and natural dissolution processes. The DWQI values of 51.40 (SB-01) and 69.45 (SB-02) classify both water sources as “good,” indicating that the water is generally suitable for consumption with minor treatment. From an environmental engineering perspective, these findings highlight the importance of simple treatment technologies, such as filtration or aeration, to reduce TDS and Mn concentrations. Ensuring sustainable access to safe drinking water therefore requires not only resource availability but also continuous quality control and appropriate treatment strategies.]]>
