Abstract: Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, preferably along a flowpath of the waste site. The method is demonstrated at waste sites, with TOC as proxy for a degradable component. The method can be recommended within a priority programme for NA-remediation on landfills.
