The distribution of chemical elements (Zn, Cu, Fe, Pb, Cd, As, Sb, Be) in the water and bottom sediments of the Belovo swamp-settler was investigated in our integrated study of geochemistry, geophysics, and hydrobiology. This swamp collects drainage escaping from clinker heaps made up of wastes of pyrometallurgical smelting of sphalerite concentrate. Water in the swamp has high TDS (Total Dissolved Solids) values, with extremely high contents of toxic elements. Bottom sediments in the swamp are a mixture of hydrogenic secondary Cu, Zn, Fe and other elements minerals. High metal concentrations lead to drastic changes in biota: phytoplankton, zooplankton, and bacteria communities. The species richness and the composition of plankton reflect the chemical composition of water of the swamp-settler and allow conside­ring it as an extreme habitat. About 90% of zooplankton individuals have a genetic mutation expressed in morphological deformations. Infiltration of the high TDS swamp water into groundwater was detected by vertical electric sounding. Contouring of settler volume and preliminary estimation of useful component resources were done; as a result, the settler could be considered as a secondary deposit. By laboratory experiments a principal possibility of solution processing is shown. In addition, extraction of some metals from solutions and sediments can decrease remediation costs for the area.
