The document discusses the root cause analysis conducted by Mangagoy National High School to determine the reasons for its lack of adequate water supply. Through a why-why analysis, the school identified three main root causes: 1) The school's hilly topography makes it difficult to access sufficient water from available sources; 2) Funds intended for installing a water system were reallocated due to the pandemic crisis; 3) The water source is shared with the surrounding community, so supply is inadequate to meet the school's needs alone.
