Ban Nong Phuk is a bicarbonate-rich mineral spring community in Thailand, where naturally mineral-enriched groundwater emerges near a floodplain pond or wetland in a low-lying agricultural landscape typical of the Thai river plains. The bicarbonate mineral content of the spring water, formed as the groundwater dissolves carbonate minerals from limestone or other sedimentary formations, gives it an alkaline character valued locally for drinking and bathing. The spring at Ban Nong Phuk reflects the mineral-rich groundwater heritage of the Thai plains, where geological formations rich in carbonate minerals produce naturally alkaline spring water accessible to farming communities who have used these resources as part of their daily life for generations.
Insider tip — Ban Nong Phuk is a bicarbonate spring at 38°C set within the patchwork rice farming landscape of central Kalasin. The alkaline water has a soft, almost silky texture that distinguishes it clearly from the iron-rich and sulfurous springs found only a few kilometers away. The variation in water chemistry across such short distances reflects the complex fractured geology of the Khorat Plateau. A modest bamboo shelter by the spring provides shade for bathers during the hot season months from March to May.
