The analysis of ecological hazards on soil pollution by oil products has been provided in the impact zone of the railway. The results of oil product migration in soils in the area of influence on section Lviv–Khodoriv are given. To study this problem, a method was used to take soil samples according to the standard DSTU ISO 10381-4: 2005. To determine the content of petroleum products used the method MVV No. 081/12-0116-03 Pochvy. Based on the results of the study it was found that contamination with petroleum products in the study area exceeds the norm in the area of influence of the railway at a distance of 5 to –50 m on average 3.5 times. It is proposed to make management decisions to prevent violations of the sanitary protection zone of the railway and the placement of agricultural plots on it. For rehabilitation of contaminated soils, it is advisable to use a natural sorbent – glauconite, which is widespread in the bowels of Ukraine. The adsorption capacity of glauconite relative to diesel fuel has been experimentally established. According to our experiments it is proved the high efficiency of the proposed sorbent, which is 90%. Therefore, in the future it is necessary to periodically monitor the condition of the soil in the area to prevent pollution. This study proves that this practice is necessary.

Sustainable development includes the process of processing and recycling of solid waste. In Ukraine, a system of accumulation of solid waste without pre-processing in landfills has been formed. As a result, anthropogenically devastated landscapes have appeared in the country, causing environmental hazard. Especially in Lviv, as well as in most cities of Ukraine, there is no waste processing plant. Non-recyclable solid waste is mostly transported to landfills throughout the region, as the Lviv municipal landfill has exhausted its resources and is in unsatisfactory ecological and sanitary condition. The presented research presents the requirements for custom vehicles that transport household and hazardous waste at the "entrance" and "exit" of the environmental logistics system. It is established that at the Lviv landfill and in its impact zone due to the devastation processes three types of edaphotopes were formed: natural, which are not physically disturbed, but contaminated with filtrates; anthropogenic, which are disturbed by construction equipment and contaminated with pollutants due to the formation of the body of the landfill; bulk, which were formed due to the import of fertile soils in order to implement the mining stage of reclamation. The obtained data show that the filtrates penetrate into groundwater and surface water, changing the reaction of the substrate environment, thereby increasing the level of environmental danger in the region. The main method of landfills decommissioning is the biological stage of recultivation, namely – vegetative reclamation.
