NGI plays a central part in the work of cleaning up contaminated soil, groundwater, marine sediments and rock. We develop methods for investigation, risk assessment and remediation.
Our ability to combine cutting edge expertise in geology, geotechnicology, environmental chemistry, hydrogeology, microbiology and measuring technology provides a unique basis for delivering revolutionary and optimal solutions to our customers.
Our customers
We offer an extensive range of geoscience services in environmental technology, and are a natural partner for building clients, authorities, consultants and contractors. Just under 15 per cent of NGI's turnover is related to environmental assignments.
NGI delivers
- surveys of contaminated soil, groundwater and marine sediments
- risk and impact analyses
- studies for and engineering of measures to protect the environment and natural resources
- pollution monitoring and control
- planning of dumps and landfills
- laboratory tests of contaminated materials
- health, environment and safety plans
Detailed list of environmental technology services offered by NGI
We have the expertise to survey and rehabilitate harbours, airports, railway and industrial areas, dumps and landfills.
What characterises us
Since the mid-1980s, NGI has provided environmental consultancy services. NGI seeks cost-effective, environmentally friendly solutions for the rehabilitation and clean-up of polluted soil, groundwater and marine sediments.
Our Environmental Laboratory has been accredited by the Norwegian accreditation body Norsk Akkreditering. Laboratory tests are an important aid in detecting contaminants in the soil and for quantifying the potential spread of environmental toxins. We also determine the possibilities for taking action through various types of model testing and through physical and chemical characterisation.
Assignments and state-of-the-art expertise
In the 1990s NGI introduced in-situ biological clean-up methods for oil and creosote, for example at the site of the international Gardermoen Airport, and later at Håkonsvern Marine Base in Bergen.
By means of projects like the Rommen landfill in Oslo, NGI has built up know-how about the planning and mapping of landfills, leakage testing and risk assessment as well as the recovery of landfill gas.
NGI is currently involved in a major project to clean up polluted sediments. It is based on an understanding of mechanisms that influence the spread of contaminants and methods that can effectively reduce this spreading. We are cooperating with the Oslo Port Authority, the Norwegian Pollution Control Authority and the Norwegian Institute for Water Research on cleaning up the polluted sediments in Oslo harbour.
Central to the work are methods and materials for handling, subsea deposition in and covering of a polluted seabed.
Primus motor for the development of the geosciences
NGI has headed a number of research programmes in environmental technology, and collaborates with research institutions all over the world. For example, we are hosting the 5th International SedNet Conference which will take place from 27-29 May 2008 in Oslo.
