Abstract

Soil contamination caused by municipal solid waste (MSW) landfills has been a concern in many countries since a significant amount of waste is still disposed of in landfills. Many studies have shown that the main list of soil pollutants from landfills include heavy metals. Therefore, important environmental problem associated with the disposal sites of municipal solid waste is soil contamination with heavy metals.

The aim of the study was to analyze and assess the state of the environment when solving engineering and environmental problems at the site of designing the second stage of the municipal solid waste in Great Novgorod. The tasks included studying the contamination of the soil cover with heavy metals (HM). In the contour of soil contamination research, a site was allocated for placing the second stage of the solid domestic waste landfill and adjacent forest districts of the Novgorod forestry.

The analyzed data were integrated into Surfer environment to construct interpolation models. On interpolation models the analysis of features of spatial distribution of HM was carried out.

The conducted studies did not reveal a significant effect of the existing landfill on the level of soil contamination with heavy metals. A feature of the spatial distribution of TMs was their low values of Kc (Kc < 1) or the values of Kc near to the background values (Kc = 1). Only in a separate section in the northern part of the test site is the accumulation of Cd. The area of cadmium accumulation coincides with the local decrease in this part of the polygon. Here background values are exceeded by 1.5–2 times. The group with the lowest concentrations (Kc < 0.5) includes Pb and Co.

The results obtained will be used to assess the stability of soils to contaminate HM.
