Kielce Lake area is a water basin located in Kielce city zone. It determines usage of areas around the basin for recreational, housing, and industrial purposes. Additionally, a state road toward Łódź city located nearby is a source of transportation pollution and heavy metals. The basin is supplied by a watercourse that receives municipal wastewater from Masłów town near Kielce. The amount and diversity of organic and inorganic compounds getting into the basin influences heavy pollution of bay waters. To reduce the degree of reservoir pollution, a pulverizing aerator was installed in the middle of Kielce Lake in May 2008. The main goal of this work is to present the results of analyzing the bottom deposits of Kielce Lake for heavy metals (Cd, Pb, Cu, Zn, Cr) during the recultivation process. Sediment samples collected at a depth of 0-20 cm twice in July 2008 and 2009 from three points located in the littoral zone of the recultivation area and two points outside it. A high concentration of analytes in reservoir sediments was indicated on the basis of the results.
