Ramboll can provide the professional skills and know-how needed for all phases of a soil or groundwater project — from preliminary studies and planning to decontamination and construction.
We work in multi-disciplinary teams made up of engineers, hydrogeologists, geologists, chemists, biologists, environmentalists and construction and infrastructure technicians. We also draw on Ramboll’s vast bank of other experts and knowledge when necessary. The soil & groundwater teams work both independently and in collaboration with their colleagues in construction, infrastructure, environment and planning.
Contamination studies
Our techicians have the skills to meet the needs of a wide range of projects: from minor local studies to major regional ones. We have the technical equipment needed for the study and documentation of soil and groundwater contamination, including a field laboratory for measuring chemical levels in water, soil and pore air samples.
Pore air measurement
Pore air measuring is a reliable, fast and inexpensive way of examining contamination with labile substances such as chloral solvents and oil and fuel products. We have more than ten years' experience, and our mobile laboratory can identify field contamination on the spot.
Risk assessment
Once soil contamination is proven, the extent and risks have to be assessed. We examine the dispersal and seepage of chemical substances in the soil, then assess the risk to groundwater, indoor climate and land-use. We perform a risk assessment based on simple and advanced dispersal models, always maintaining focus on our clients’ needs.
Indoor climate analysis
In indoor situations, we can examine and provide consultancy on chemical substances that originate from chemical products or from seeping soil contamination. We use our own measuring equipment and collaborate closely with recognised laboratories for the chemical analyses.
Models for contamination dispersal
Ramboll is highly experienced in the use of models to create and simulate contamination dispersal. We input data on geology, hydrogeology and chemicals into an IT model and create a picture of the strength and dispersal of contamination found in soil and groundwater. This provides decision-makers with a tool for risk assessment.
Preventative measures
Ramboll's experience in the field of preventative measures includes:
- traditional removal activities using off-site disposal or on-site treatment of contaminated soil
- preventative pumping activities
- purification of free-phase contamination
- construction-related activities
- in situ purification by either traditional or more-advanced biological methods
Ramboll uses some of the most advanced equipment available for testing preventative measures.
Environmental assessment of chemical substances
The number of chemical substances in use is on the increase and regular environmental assessments on their application and disposal are needed. We collect, interpret and assess chemical and toxicological data, and conduct environmental assessments of the consequences of major public construction projects. Tunnel-drilling chemicals, CFCs and flame retardants are some of the chemicals involved.
