Background: There is interest in characteristics of mineral waters from two famous hot springs in Ranong province, Thailand, including Raksawarin and Porn-Rang hot springs. Aims: To objective is to determine characteristics of thermal mineral waters of Ranong region and describe its classification and therapeutic indications. Material and Methods: Mineral waters were collected from Rahsawarin and Porn-Rang hot springs. All analyses were conducted according to American Public Health Association. Temperature was measured in the field at the time of sample collection. Analyses of fecal coliforms and total bacterial count were performed. Physical-chemical analyses were used to evaluate pH, total dissolved solids (TDS), and conductivity. Total hardness was measured in the laboratory by titration. Metals (Al, Si, Fe, Mn, Pb, Cd, Ni, Cu) were measured by graphite furnace atomic absorption spectroscopy (GFAAS); major ions (Ca, Mg, Na, K, Cl, F, HCO3-, SO4, S2-) and nutrients (NH4, PO4-, NO3) were measured by ion chromatography technique. Results and Discussion: The mean of pH, TDS, and conductivity values observed for hot springs were met to reference value of Thai tap water standard by WHO guideline. Neither hot spring contained fecal coliform bacteria. Chemical parameters were also within standard excepted aluminum concentration. Potassium levels from mineral waters were also high. Ranong mineral spring water can be thermal waters and define to hot waters. Ranong mineral spring water can be define to fresh and low sodium water. Conclusions: Our suggestions regarding this mineral water indication were properly for external use and may concern in case of drinking.
