Metal and organic matter contents in a combined household and industrial landfill

Ostman M, Wahlberg O, Agren S, Martensson A

Abstract

A combined household/industrial landfill in a humid and cold temperate climate was characterised with respect to its chemical composition. Cores taken at three randomly chosen sites on the landfill and at different depths at each site were analysed. Carbon, nitrogen and pH were measured by standard laboratory methods. The chemical elements analysed included metals and the non-metals B, P and S. pH ranged between 8.0 and 8.5. The total carbon content was in the interval 4.5-26.9% and the total nitrogen content in the interval 0.05-0.48%. The C/N ratio was high, indicating that there was not enough nitrogen available to ensure the stabilisation of carbon. The metal contents varied substantially. The water and carbon contents were related to each other as well as to the metal content, which increased with the content of water. Based on the results obtained regarding the chemical composition of the landfill, it is evident that the landfill consists of two layers. This indicates that the landfill body might have different levels of chemical development, due to water content, and different long-term leachability in the future. (c) 2005 Elsevier Ltd.
