Environmental Technology

MRM works on small and large projects involving environmental services and investigations. We offer consultancy with regard to environmental ground investigations, advises on recommended course of action and designs remediation plans. We can perform self-monitoring for our clients in accordance with the environmental legislation. We can handle communication with authorities, do project management and perform various environmental analyses in our accredited laboratory.

  • Environmental ground investigations for:

- Transfer of property

- Construction of new buildings or reconstruction of existing buildings.

- Investigation, assessment and design of remediation plan in case of environmental accidents

- Change in land use

- At the request of supervisory authorities

- Design planning

  • Produce data prior to construction work and/or data for requirements specifications prior to construction projects.
  • Perform quick filed analyses with our well-equipped mobile environmental laboratory, which includes, among other things, PID and XRF equipment.
  • Localise buried cisterns with ground penetrating radar.
  • Risk assessments advise on redemended course of action, design remediation plan, handle communication with the authorities and perform follow ups and post remediation control.
  • Perform remediation contor both during and after treatment
  • Perform environmental laboratory tests. 
  • Design and carry out self-monitoring programmes with subsequent evaluation and documentation.
  • Create and handle permit applications for aquatic operations in accordance to the Environmental Code.

All of our surveys are done using quality-assured routines and standardised methods of sampling and sample preparation. We customise the project in order to achieve the best possible solution for the customer.

We also have experience in working during construction in progress with minimal disturbance and delay caused to the project. Our great flexibility allows us to be on site quickly and to adapt to the customer's procedure and schedule.

Sulphide Soils

Along the coast of the Norrbotten, Västerbotten and Österbotten, fine-grained marine sediment forms a relatively common type of soil. Many of these sediments have been formed during periods when the sea was nutrient-rich and the climate favourable for a high level of biological production, which gave the sediment a high concentration of organic material. As the organic material broke down, oxygen was consumed oxygen was consumed creating an anoxic seedbed allowing iron sulphides to precipitate. The ever-continuing rising of the land has resulted in the sulphide-rich sediment now being found above sea level.

The handling of sulphide soil involves both geotechnical and environmental problems. The high water content of sulphide soils, as well as the high organic concentration, make them very prone to compression when subjected to loads. Environmental problems arise when sulphide soil is subjected to oxygen, which takes place when sulphide soil masses are dug up or when groundwater levels vary. When sulphide minerals are exposed to oxygen, they oxidise into sulphates which results in low pH leaching of metals into the drainage water coming from the ground. The soil that is formed after the oxidation of a sulphide soil is called a sulphate soil and often has a very low pH and a high level of electric conductivity.

MRM is very knowledgeable about sulphide soils. We can assist and give advises in both an environmental perspective and a geotechnical perspective, and we also undertake leaching tests in order to assess the acidification potential and acidification effect. We can even conduct tests directly out in the field during construction projects in progress.
