Title: Results of Microbiologic Investigations of Water-Development Works

Results are presented for multiyear field investigations of the effect of microbe colonies on components of water-development works. Concrete, metal, and geologic rocks were studied as component parts of the bed of concrete dams functioning in various climatic zones. The participation of lithotrophic bacteria in processes involving corrosion failure of the metal, concrete, and rock beds of dams is established, and causes of intensification of microbe activity are exposed. The need for monitoring the composition and number of microorganisms-biodestructors is substantiated in the water of a reservoir and observation wells, as well as on the surfaces of structural components of water-development works for monitoring of the safety of the concrete dams.
