[Hydraulo-geologic assumptions of biological purification processes in the subsoil].

The use of microbiological methods to remediate contaminated underground and ground water may become both effective and economically advantageous. To exploit the potential advantage of these methods, one must start early enough prior to the treatment investigate the degradability of the contaminants present, and the geo-hydraulic conditions existing at the site. It seem to be advisable to involve neutral experts at this stage of preparation, i.e., those who are personally not indebted to one specific remediation method. At the present time, the progress in the biological remediation techniques seems to allow their use in numerous cases of the environmental contamination under economically attractive conditions.
