Organic and inorganic pollution can increase microbial biofilms formation on sandy rocks of the upper aquifers. The activity of microorganisms in biofilms can cause very effective remediation of the aquifers, and their study is important in the framework of groundwater bioremediation. Chemical and taxonomic transformation of the biofilms microbial community of upper aquifers nearby radioactive waste and uranium sludge repositories polluted with nitrates, chromate and uranyl ions after single glucose stimulation was studied in the work.
