“…Previously, the excess of permissible concentrations by it in borehole samples (point 2, Fig. 1), a spring (point 6) and the river Kadalinka in the drought period, we interpreted [5,6] as a consequence of the inflow of Si with the infiltration waters of the ash dump. But the data of the borehole 241 (point 3) which is located much closer to HAD and which Si concentrations in water is turned out to be below 10 mg / l ( Table I), show that its high contents can be formed in situ, the same nature of high concentrations in excess of MPC for Mn, Fe, Co and Ni.…”

“…[2-4 and others] There are few publications describing the influence of coal energy on the geochemical characteristics of groundwater. In addition to our own works [5,6] we consider works of other scientists [7][8][9]. The purpose of this study is to present the nature and extent of the technogenic changes in the chemical composition of groundwater as a result of filtration leakages of one of the ash dumps, hence, expanding the database on the problem under consideration.…”

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 SO4 2-, 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.

“…Hydrocarbonate composition of surface and underground waters is typical for these zonal and climatic conditions , Zhuldybina 2010, Zamana et al 2011. The hydrochemical composition of lake waters from a two-component -sodium hydrogen carbonate until the 60s of the last century was transformed into a three-component -sulfate-hydrocarbonate-chloride sodium-calcium-magnesium (Tsybekmitova 2016, Usmanova et al 2018 (Table 1). The water composition change was due to the ash dump leakage.…”

In this study, contamination of potentially toxic elements (Cr, Mn, Cu, Zn, Hg and Pb) and species dominant in the fish community of Lake Kenon – Carassius auratus gibelio (Bloch 1782) and Perca fluviatilis (Linnaeus 1758) – were investigated. Chemical elements in samples were determined by atomic emission spectrometry (iCAP-6500, Thermo Scientific, USA) and mass spectrometry (X-7, Thermo Elemental, USA). It was reported that water in Lake Kenon contained low concentrations of the studied metals. The bottom sediments are enriched with Mn, Zn, Hg and Pb. Bioaccumulation factors of chemical elements accumulated from the surrounding water for P. fluviatus and C. auratus gibelio in descending order are as follows: Zn > Pb > Hg > Cu. P. fluviatus accumulates Hg in equal measure from both water and bottom sediments. Manganese and mercury are accumulated in the muscles of C. auratus gibelio from bottom sediments. The high accumulation ratio of Zn and Hg in C. auratus gibelio was obtained from Chara sp. (24 times) and Chironomus spp. (38 times), respectively. High accumulation ratio of Zn (26 times) and Hg (29 times) in P. fluviatus was obtained from amphipods. At the same time, Hg in P. fluviatus muscles was accumulated at high level from Chironomus spp. (67 times). In this way, management decisions for mitigation practices in Lake Kenon should be focussed on for the disposal of wastewater from the ash dump contaminated with chemical elements.

“…24 кн глубиной 77,2 м. Взаимодействие техногенных вод с золошлаками, почвами и породами приводит к понижению их кислотно-основных свойств [9]. В результате фильтрации через золошлаковые отложения фтор удаляется из фильтрующихся вод, что обусловлено процессом образования флюорита, по которому воды отстойника пересыщены [8]. В сравнении с водами отстойника в подземных водах уменьшается содержание кальция, но растут концентрации магния, за счет которого увеличивается жесткость воды [10].…”
