Substances with noxious effects on humans and the environment can be liberated when water comes into contact with solids. Precipitation reactions can lead to the fixation of such substances. This can have a negative impact on the operation of technical equipment but, by contrast, can also be exploited to immobilise pollutants.

To be able to carry out effective and economic measures directed at damage prevention, we have to understand the chemical reactions that occur.
To this end the necessary information is collected:

• Geochemical and hydrochemical conditions at the site
• Characterisation of the pollutant source
• Pollutant release
• Relevant substance transport paths
• Microbiological metabolism
• Efficacy of geochemical barriers
• Impact on the biosphere

We employ chemical, microbiological, geotechnical and mineralogical analyses as well as the proper sampling methods and realistic leaching tests when identifying solutions to your problems. Hydrogeochemical mathematical modelling used for thermodynamic interpretation of water analyses and to predict reactions deliver the information needed to understand the processes involved.
