Abstract

The filtrational leakages from the ash dump of the Chita TPP-1 led to the change of the natural hydrogen carbonate and sulfate hydrogen carbonate composition of groundwater to the sulfate and the hydrogen carbonate sulfate, and to the formation of the aureola of nonstandard drinking water with the excess of MPC for SO42-, Mg, F, Si, total hardness and salinity level in the area of about 10 sq. km. The increase in Mg concentrations occurs in the most aquifer system, in the rest criteria - by means of ash dump waters. One of the characteristic features is high alkaline. The authors explain this by the hydrolysis of calcium oxide CaO in the ash. Inflowing of mineral substances from watercourses, draining the groundwater of the aureole, and subaqual discharge into the lake Kenon, the cooling pond and the source of technical water supply for TPP-1 caused the changes in the hydrochemical characteristics and deterioration of the quality of the lake water, which are not restored by pumping less mineralized water from the river Ingoda.
