140 Mu 7 Sa Yai Som is a bicarbonate-rich mineral spring in the seventh mu subdivision of Sa Yai Som village, Nong Khai Province, northeastern Thailand, contributing to the dense network of naturally occurring mineral spring sources that make this village one of the most geothermally diverse communities in the Thai Isan region. The bicarbonate mineral water at this address provides local residents with a naturally alkaline, mineral-enriched water source valued for bathing and drinking in the traditional Isan approach to natural spring water use. The spring reflects the carbonate geology of the Khorat Plateau, where limestone and sedimentary formations enrich artesian water with dissolved bicarbonate minerals as it rises through the geothermal field beneath the Sa Yai Som community.
Insider tip — This bicarbonate spring in Kanchanaburi's Sa Yai Som area flows at 38°C and is part of the same fault-fed thermal system that produces numerous springs across this district. The slightly effervescent quality of bicarbonate-rich water gives a pleasant tingling sensation during soaking. Western Kanchanaburi's border landscape provides a dramatic backdrop of forested hills and occasional waterfalls. Combine with a visit to the Erawan National Park nearby for a full nature day.
