This paper presents the results of mineralogical, geochemical and geophysical studies of Zn-Pb processing waste dump stored at the turn of the 19th and 20th centuries. The mineral composition of wastes was identified using the XRD method, the contents of Zn, Pb, Fe, Mn, Cd, and Tl were determined using the AAS method, whereas the characteristic features of metalliferous grains were examined using the ESEM method. High geochemical mobility of these metals reduces plant succession and brings about the pollution of the former Zn-Pb ores mine areas. High contents of Zn-Pb-Fe sulfides and unstable, hydrated Pb, Fe, Pb-Fe sulfates result in distinctly raised levels of heavy metals (Zn 121,501 mg kg⁻¹, Pb 208,869 mg kg⁻¹, Cd 477 mg kg⁻¹). Various waste types and surrounding Triassic or Quaternary deposits differ significantly in mineral composition, and consequently in physical properties such as electrical conductivity of top soil horizons. This enabled using geoelectric methods for the purpose of this study, and contouring mine wastes in the polluted areas. The field geophysical survey was carried out with a high-resolution conductivity meter (Geonics EM31-MK2).

Our investigation was localized in the area of fuel base A of the former Soviet firing ground Borne Sulinowo, where petrol contamination of soils had been observed. The suspenssion of yeast strain Yarrowia lipolytica A–101 was introduced into twelve one-metre deep bore-holes. The process of bioremediation was controlled using electromagnetic and resistivity methods, and microbial enumeration was done on Hy–Check slides. The measurements were carried out along the same profile in spring 2003, autumn 2003 and spring 2004. The significant increase of electrical conductivity of soils was observed in the vicinity of bore-holes with introduced yeast. The study showed the ability of Yarrowia lipolytica yeast to remedy petrol contaminated soils and the efficiency of applied geoelectrical methods to this process monitoring.
