ABSTRACT

Metallurgical wastes are deposited in landfills or are being recycled, mainly as material used for engineering work. They are also sources of pollution in the groundwater environment. For this reason, it is necessary to explore environmentally safe ways of using them.
Environmental impact assessments of waste can be made on the basis of static or dynamic laboratory tests. The alternative is to carry out lysimetric research. However, this kind of research is rarely performed due to the degree of complexity, cost and duration.
This paper presents the preliminary results of a 12-year lysimetric research project concerning the metallurgical waste deposited at the landfill site Lipowka in Strzemieszyce Małe, Southern Poland. The research investigated the quantity and chemical composition of the leachates and rainwater. Measurements were conducted in 2005, 2008/2009, 2014/2015 and 2016/2017.
The preliminary results confirm the significant negative impact of leachates from the Lipówka landfill site on groundwater quality in its vicinity. This risk is caused mainly by leaching from as sulfates, potassium, chlorides and nitrogen compounds. Mn, Ba, Sr, As, Hg, Sb, B were also found in the initial phase of the study. After 20 years of experiment, the leaching of the examined substances decreased up to 20 times.
