The paper summarizes newly obtained data on the chemical and isotopic composition of groundwaters in the southern part of the Kuznetsk Basin. The territory is demonstrated to host groundwaters of three types, which were distinguished according to the chemical, isotopic, and gas composition of the waters. The waters of type 1 are widespread in areas of sluggish water exchange in coal-bearing terrigenous rocks, bear mineralization of 0.2-4.7 g/L, have pH 7-10, and N-2-CH4 and CH4-N-2 gas composition. Their source is biogenic (coal) with delta C-13 from -17.1 to -4.2 degrees. The sodic waters of type 2 were found relatively recently and only locally, are hosted in the same rocks but at more hampered water exchange, and have mineralization of 5-25 g/L, pH 7.7-10, and CH4 gas composition. These waters are noted for an anomalously isotopically heavy isotopic composition of their carbon delta(13)() = 0.2-30.9 degrees and delta(13)(CO2) = -3.2-22.3 degrees.
