Soil, Water, & Legacy Pollution

Today, in the face of a consistently changing environment in terms of predictable living conditions and economic activities (key word climate change), numerous applications are needed that especially address the challenges related to soil protection and water management. In response to these issues, we have successfully offered professional solutions tailored to our clients’ requirements for more than 25 years.

We provide concentrated expertise ranging from soil surveys to soil protection according to the BBodSchG, from exploration and monitoring programs, planning and supervision of technical ground equipment to ecological monitoring of construction projects in terms of soil protection / waste provisions, from ground surveys to geotechnical engineering. As specified in the BBodSchG, Article 18, our team comprises accordingly accredited experts for subject fields 1, 2, 5, and 6.

Compliance with these preconditions ensures that the relevant authorities accept the results of the expert and planning services rendered within the scope of the surveys of contaminated sites according to the BBodSchG and BBodSchV. We render all services related to the exploration, assessment, and clean-up of legacy pollution / contaminated sites, land recycling, and remediation planning according to the BBodSchG, including remediation monitoring.

Experience gained over decades regarding the analysis, modeling and simulation in the field of water management and water development provides a basis for reliable recommendations to be made with regard to flood protection and geothermal energy.
