Abstract

Deep bedrock groundwaters contain very low amount of organic matter and microbes utilize mainly methane and carbon dioxide as C source. Organic matter originating from the surface or from construction materials and low radioactive wastes may also be C sources for microorganisms and accelerate their activity. Gas generation potential of organic compounds is dependant on their chemical and physical structure which can be determined by biodegradability tests. In 1997 a large scale gas generation experiment was started to study biodegradation of low radioactive wastes and gases generated in real conditions. Experimental design, results and future prospects will be discussed. In addition an overview of present research activities concerning molecular microbial characterization of the Olkiluoto and other bedrock aquifers of Finland will be discussed.
