This research aims to study the water quality of tap water sources in Ban Tapao, Ban Khee Nak, and Ban Hat areas. The study analyzes the impact of physical and chemical factors on water quality, leading to water management planning, water resource conservation, and raising community awareness of the importance of shared water resources for proper and appropriate water allocation. Water samples were collected from three locations: Point 1: Tapao community water well; Point 2: Khee Nak community water well; and Point 3: Ban Hat community water well. Each sample was collected once. Water quality parameters measured included water temperature, electrical conductivity, dissolved oxygen, pH, nitrate, and nitrite. The research results showed that at Point 1, the tap water well in the Tapao community... The average water temperature at point 1 was 30°C, pH 7.37, nitrate levels 0–1 (mg/L), nitrite levels 0–1 (mg/L), electrical conductivity (EC) 206 (µg/L), and dissolved oxygen (DO) 5.5 (mg/L). Point 2, the community water supply well in Ban Khee Nak, had an average water temperature of 28°C, pH 7.83, nitrate levels 0–1 (mg/L), nitrite levels 0–1 (mg/L), electrical conductivity (EC) 112 (µg/L), and dissolved oxygen (DO) 8.0 (mg/L). Point 3 was the community water supply well in Ban Hat. The average water temperature was 29°C, pH 7.24, nitrate level 0–1 (mg/L), nitrite level 0– 1 (mg/L), electrical conductivity (EC) 114 (µg/L), and dissolved oxygen (DO) 3.0 (mg/L). From the test results, it can be seen that all three water sources studied are suitable for consumption and domestic use. They are classified as Type 2 water, according to the National Environmental Board Announcement No. 8 of 1994. This indicates that the water quality is suitable for agricultural consumption and wildlife conservation, meeting the standards for tap water production.
