The composition of leachates provides crucial information on
the current status and ongoing processes in a landfill body, particularly
with respect to reactivity or stability of the organic matter in
municipal solid waste (MSW). This knowledge provides an important
basis for further decision making, like the selection of suitable
aftercare measures on MSW landfills. Thus, a new monitoring
approach for abandoned and remediated landfills was developed
using leachate characterization by means of FT-IR spectroscopy
