We present the results of geophysical investigations, namely electro-potential tomography sounding, self-potential method and ground magnetic surveys. Dump, storage site of industrial and domestic wastes in Rostov-on-Don and slurry water storage site in Taganrog are the objects of our unvestigations. The integrated interpretation of the data obtained has permitted to estimate the infiltration processes, to specify the layout of infiltration zones and to reveal the location of metallic wastes. The results of the investigations have allowed to justify the effectiveness of the set of geophysical methods for estimation of environmental hazards of the objects under investigation. The engineering solutions for diminishing the effect of the considered technogenic objects on ecosystems have been proposed.
