N2 - The purpose of this study was to assess the groundwater contamination from a sewage sludge landfill. The analysiswas carried out in 2017 in accordance with the requirements of the national legislation for monitoring landfillsand priority pollutants. The samples of groundwater from the landfill were taken from 25 observation wells, fromdepths of 45–60 m. The status and dynamics of changes in the landfill groundwater quality were estimated accordingto the data from the groundwater observation wells of the city observation network with regard to the chemicalcomposition of groundwater and national standards of groundwater quality. The forecast estimates of a low level ofpollutants entering groundwater through the soils characterized by low filtration properties were not justified. Theconcentration of heavy metals in groundwater was within the following range: Fe > Mn?> Zn > Al?> Cu > Ni?> Pb >Cd?> Hg. The excess concentration of the nitrogen-containing pollutants was observed within the range from 1.5 to76 (on average 10 times) above the background value. The organic contamination of landfill groundwater (COD) is2–9 times and BOD5 – 1.5–3 times higher than the average background value of groundwater observation wells inthe city network. The probable cause for the pollutants entry into groundwater is associated with lithogenous andexogenous fracturing of the rocks and insufficient efficiency of the existing anti-filtration system of the landfill.
