The hydrochemical characteristics of water objects, including lakes and a number of streams and rivers as well as technogenic sedimentation tanks located in the areas of placer gold mining have been studied. Total dissolved solids, contents of individual ions, total hardness (TH), total suspended solids (TSS), and acidic pH have been determined. Lake water is ultra-fresh with total dissolved solids of 15.08-52.6 mg/l. Increased values of this parameter have been found in lakes located in the

Water bodies from placer mining sites are characterized by increased total dissolved solids (up to 394 mg/l) and total hardness (average = 2.20 mg-eq/l). In some reservoirs, low pH, high levels of ammonia, and iron exceeding ecologically admissible values have been established.
