In the 2003–2007 timeframe the authors conducted the analysis of changes in chemical composition of both ground and surface waters at an industrial waste disposal area of JSC “Plastic” according to the following markers: pH index, mineralization, hardness, sulfate ion, chloride ion, Fe, ammonium ion, Ni, Zn, Cr, Cd, Mn, petroleum products, suspended materials, phenols, chemical oxygen demand with permanganate as the oxidant and phosphate ion. They studied the pollution of geo-ecological environment and the assessment of pollution scale based on the observations of ground water dynamics and its quality change. In surface waters close to an industrial waste disposal area there were high concentrations of sulfates, Fe, Mn, petroleum products, and phenols, which exceeded maximum allowable concentration (MAC). A high index of organic pollution was also determined.
