Fluoridated, low - mineralized thermal water in Phuoc Nhon area, Hoa Khuong commune, Hoa Vang district, Da Nang City, Vietnam

Abstract

Phuoc Nhon thermal water at Hoa Khuong commune, Hoa Vang district, Da Nang City (prior to the provincial administrative merger on 1 st July 2025), Vietnam. The thermal mineral water is distributed within a fractured rock aquifer hosted in the intrusive rocks of Dai Loc Complex. Methods used in this study consist of basic field survey of hydrogeology, self - flowing water discharge tests, pumping tests, and thermal mineral water sample analysis. The thermal mineral water is classified as fluoridated, low mineralised thermal mineral water. Its exploration reserve is estimated at 425 m 3 /d with good quality, satisfying all national criterials for the use of domestic supply, bathing, and medical treatments. This is one of the valuable fluoridated natural mineral water sources, which should be properly managed, exploited, protected, and utilized in a scientific, rational, and efficient manner.
