Opis (eng)

Potential significant environmental impact of landfill leachate migration is pollution of soil, groundwater and surface waters. Hence leachate analysis and monitoring of groundwater quality are important indicators of potentially altered environmental quality. The main objective of the study was determination whether the sanitary landfill in Serbia has a measurable impact on groundwater and soil quality. We presented physico-chemical analysis results for groundwater (four facilities/ piezometers PI, P2, P3, P4) and wastewater samples (leachate collection pool and settling tank). All ground water samples had pH in range 7.1-8.3, chemical oxygen demand (COD) 39-108 mg 02/I, total organic carbon concentrations (TOC) 4.9-21.2 mg C/l. Metals, whose concentrations are statutory in R. Serbia in terms of remediation value and values that may indicate a significant contamination were quantificated. In groundwater samples, concentrations of examined metals generally were below detection limit. For P2 and P3 piezometers, As and Cr concentrations were above the regulatory limit (>60 micrograms/l and >30 micrograms/1, respectively). Obtained results show that Ba2+ was the most abundant metal present in all groundwater samples (7.5-157 micrograms/l), although in concentration range below regulatory limits. Waste water samples pH was in range 7.2-8.9, COD 168-5563 mg 02/I. TOC concentration was in range of 13 to over 1000 mg C/l. In waste water samples, only Cu, Cr and As concentrations were above regulatory limits. In leachate collection pool Cu concentration in two from six samples is above regulatory limit (>75 micrograms/l), as well as Cr concentration in all six samples (>30 micrograms/l). As concentration in leachate collection pool in five of six samples was above regulatory limit (>60 micrograms/l). In waste water samples from settling tank As concentration in one of four samples was above regulatory limit. The obtained results indicate good water quality from piezometers that surround sanitary municipal landfill and suggest the absence of high risks for contamination of soil, surface and ground water.
