Usually all three phases (solid, liquid and gaseous) are encountered in the soil. Similarly, all three phases can be affected by contamination. Soil treatment requires a holistic approach which takes all three phases in the soil and their complex interactions into account.

Sediment transport
In the field of hydrogeology, we offer selected training equipment which will help you to teach the basic hydrogeological processes in soils in a practical and clear manner. Issues such as seepage of precipitation, seepage flows and groundwater flows are studied.

Soil treatment
The main objective of soil treatment is to protect the groundwater and – as far as possible – to restore the original function of the contaminated soil. A number of different methods are available depending on the type of soil and type of contamination.
