Abstract      

This project assisted the Royal Initiative Discovery Institute and provides supporting data to ensure a sufficient and safe water supply for Baan Sai Ngam Moo 13, an ethnic Hmong village in Sop Bong Subdistrict, Phu Sang District, Phayao. The study examined community water usage patterns, identified sources of contamination, and assessed the hydrogeology of local water resources. We conducted interviews, made field observations, and collected data to analyze the current water distribution system and its challenges. The findings reveal inadequate water management, excessive chemical use, and poor infrastructure maintenance contribute to water quality issues. Recommendations for sustainable water management strategies are provided to enhance long-term access to clean water based on these results.
