Phu Ninh hot mineral water source in Tam Dai commune, Phu Ninh district, Quang Nam province is a source of good quality water, stable over time and has abundant reserves, so it is valuable to be used as bottled water for refreshments, used for bathing and curing diseases. Phu Ninh mineral water has a wide distribution area with mineral water containing formations of the Kham Duc formation [5], which is a hot mineral water source with high pressure (at the current borehole K1).

Research results show that Phu Ninh mineral water source has up to 3 components (3 criteria) that meet the standards of mineral water identification (according to Circular 52/2014/BTNMT), which are: high mineralization (TDS: 2,105g / l > 1.5 g / l), high content of metasilic acid (H₂SiO₃) (reaching 85.88 > 50mg

/ l) and high temperature (71^oC >30^oC). The chemical type of mineral water is sodium-calcium chloride. This source is identified as very hot, highly mineralized silicate mineral water source.

Research results from pumping test with the lowering periods and long-term experimental exploitation have determined that the mineral water reserve in borehole K1 has reserves of grade B of 216 m³/day, reserves level C1 is 154.66 m3/ day.

When exploiting and using this mineral water source, it will contribute to improve the life and socio- culture for the people in the area. Therefore, it is essential to invest in the proper exploitation and use of this mineral water to meet the needs of bathing, drinking, and ecotourism to avoid wasting this precious natural resource.
