Project long title

Development of quality assurance methods for the utilization of excavated soil with geogenically determined heavy metal contents

Project description

The ReSoil project addresses companies, which produce compost soil and is engaged in the development of quality control methods for the reutilisation of excavated soil with geogenic heavy metal contents. So far excavated soils and from those produced products are evaluated about their suitability – especially concerning pollutants – for land recultivation. In doing so, a couple of heavy metals have priority. There is no differentiating between content and effect of the pollutant. This is where the ReSoil project steps in. The main goal is to assess the connection between total content of heavy metals (As, Cd, Cr, Cu, Hg, Ni and Pb) and their toxicity by means of laboratory tests and big- and small-container-experiments along with developing a screening test including toxicity determination for the reutilisation of excavated as well as composted soil.

Sampling for screening soils with high geogenic heavy metal contents

Chromium availability in a particular styrian soil, determined by a sequential elution procedure (Tessier 1979)

Aims of the project

The aims of the project ReSoil include:

1. Developing a sequential elution test to assess the harmful impact of heavy metals in excavated soil.
2. Validating big-container-tests for quality control of compost soil.
3. Knowledge of reutilisation of excavated soil with geogenic heavy metal contents as a component in composted soil within a comparable geological region.
