Hot groundwater was discovered during the 90s of the 20th century in Duyen Hai commune Hung Ha district Thai Binh province but no exploration and evaluation studies were conducted to determine the potential of the mineral and hot water in the area. Spatial distribution of groundwater temperature and the total mineralization in the study area of the mineral and hot water occurrence and its surrounding area has allowed to identify the area of mineral and hot water origin and that the hot water belongs to average hot water with a temperature of about 49 degrees Celsius. Analyzing the tectonic structure has showed that the mineral and hot water is formed at an area surrounded by three class-2 faults which have a vertical displacement amplitude of 100 m - 1 000 m and a destructive zone of over 100 m. This is an area with favorable conditions to bring geothermal source and dissolved minerals in surrounding rocks to groundwater in the above aquifers. The approach presented in the paper can be applied to conduct research on potential mineral and hot water in other .
