ANNOTATION:
The article presents the results of investigation of groundwater microorganisms from deep disposal facilities for liquid radioactive waste (RW) in Zheleznogorsk and Seversk carried out in 1998–2016. The microbial community investigated in groundwater is physiologically diverse, but is low geochemical active. It includes aerobic organotrophs and anaerobes (fermenting, denitrifying, sulfate-reducing, and methanogenic microorganisms). Paper shows that that injection of RW into aquifers increases population of microorganisms and rates of anaerobic microbial processes resulting from the use of organic and mineral components of the waste. Bacteria isolated from groundwater were found to be capable of nitrate and radionuclide recovery, radionuclide sorption, and affecting the ambient redox
potential. Microbiological monitoring of groundwater is required for evaluation of long-term environmental safety of the deep disposal facilities for liquid RW.
