CHARACTERISTICS AND EXPLOITATION RESERVES OF HOT MINERAL WATER AT NKNS BOREHOLE, BAO YEN COMMUNE, THANH THUY DISTRICT, PHU THO PROVINCE

Abstract

The source of hot mineral water at NKNS borehole has good quality that can be used for many different purposes. Mineral water originates from deep ground, accumulating and distributing in forous sediment formations. The results of research and experiment show that the hot mineral water in the area of NKNS borehole is distributed at a depth of 27.5 to 70m, located in the Pleistocene aquifer (qp). Mineral water belongs to pressurized water, the static water level at NKNS is 4.87m. Research results through pumping tests shows that the borehole has quite abundant exploitation reserves, the total exploitation reserve is 1,070.50 m³/day, of which grade B reserve is 704.16 m³/day and grade C₁ reserve is 366.34 m³/day. The value of water drawdown reaches 5.21m when sucking water with a flow of 704m³/day. With 86 analyzed mineral water samples, it shows that the water quality is stable over time, which can be used for drinking, bathing, and ecotourism. The type of mineral water identified is Sulfate-Sodium, hot. The cluster water absorption experiment shows that mineral water has no hydraulic relationship with groundwater in the upper aquifer (qh). This is a valuable mineral water source that needs to be exploited and used effectively
