Abstract

Industrial production is inevitably accompanied by the formation and accumulation of significant volumes of waste, which have a negative impact on the natural environment, including groundwater. In the Republic of Belarus, one of the main sources of such impact is accumulated large-tonnage waste from the chemical and woodworking industries, presented in the form of dumps and sludge storage facilities. For the period 2000–2022 the dynamics of the formation and accumulation of industrial waste in the Republic of Belarus has been analyzed. A general trend has been established for the growth of production waste generation with an average annual rate of 4.8%. Accumulated production waste over the same period of time increased by 88.7%. Halite, phosphogypsum, and hydrolytic lignin are the main sources of large-tonnage waste, accounting for up to 99% of the total production waste volume. The component composition of large-tonnage accumulated industrial waste and groundwater pollutants, including chlorides, sulfates, phosphates, and ammonium nitrogen, has been considered. The pathways and mechanisms of pollutants migration within industrial waste disposal territories has been generalized. Compaction of fresh dumped waste, precipitation leaching from the surface of dumps, and wind erosion are the main causes of them in general. The dynamics of pollution development within industrial waste disposal sites has been assessed. It indicates persistent groundwater pollution over decades. Contamination can occur in both groundwater and middle water. Concentrations of pollutants are tens and hundreds of times higher than the maximum permissible concentration for drinking water. The spreading of pollution, depending on the object of impact, can happen in areas that range from hundreds to thousands of hectares.
