SELECTION OF OPTIMAL PARAMETERS FOR FUTURE RESEARCH MONITORING PROGRAMMES ON MSW LANDFILL IN NOVI SAD, SERBIA
Leachate and groundwater samples were collected during quarterly sampling campaign, on unsanitary municipal solid waste (MSW) landfill in Novi Sad, Serbia, from April 2014. to February 2015. Determination of T, pH, EC, DO, BOD5, COD, nitrite nitrogen (NO2-N), nitrate nitrogen (NO3-N), ammonia nitrogen (NH4-N), total nitrogen (Tot N), total phosphorus (Tot P), boron (B), sulphate (SO42-), permanganate index (KMnO4), and cations of metals (Ca, Mg, Na, K, B, Cr, Ni, Zn, Fe, Cd, Pb and Al), was performed. The comparison of the results obtained for leachate and groundwater samples and the limit values from laws and bylaws, literature, and the WHO guidelines, was performed. Principal component analysis (PCA) as a multivariate statistical method was later used for data filtering in order to classificate the potential sources of pollution. Four principal components (PCs) were identified, explaining 93,802 of the total variance. Cluster analysis (CA) was applied for grouping the sampling locations on MSW landfill in Novi Sad in accordance with the obtained values of physico-chemical parameters. Information obtained by CA has enabled the developing of future research monitoring programme, for each sampling location on the landfill in Novi Sad. The results obtained from this study could be very useful for planning of monitoring programmes on the landfills with similar structure and waste management practice.
