Remediation of soil

Fortum offers a wide range of remediation methods as well as solid expertise in the restoration of contaminated land areas.

Is your problem contaminated soil?

Contaminated soil at an industrial site, old service station, landfill or sawmill, for example, often decreases the value of the property or jeopardises the environment. We offer the remediation of contaminated sites in the form of all-inclusive projects or subprojects. In all-inclusive projects, Fortum is responsible for the successful completion of work from beginning to end on a turnkey basis. In addition to our expertise, the benefits of our services include our ability to customise treatment methods to meet the customer's needs.

The most typical hazardous, soil-contaminating substances are

  • various heavy metals, such as arsenic, chromium, mercury, lead and zinc,
  • oil products, such as petrol and various oils,
  • chlorophenols,
  • furans,
  • PAH compounds,
  • PCB compounds,
  • insecticides and pesticides, and
  • various solvents.

Our wide range of remediation methods ensure a good outcome

We select the soil remediation method according to the substances that caused the contamination, the substances' level of concentration, the size of the area, the nature of the soil and the risks associated with remediation.

Contamined soil may be remediated in situ, (without transferring soil or groundwater), on site, or off site (the soil or groundwater is transferred elsewhere to be treated). We can handle all phases of the cleaning project from the demolition of any old buildings on site, water treatment, excavation and transport of the soil mass to the reutilisation of the treated mass and the construction of infrastructure in the area.

The most common methods we use for soil remediation are:

  • mass replacement,
  • soil vapour extraction,
  • composting,
  • stabilisation,
  • insulation, and
  • thermic treatment.

The metal, rocks, concrete, wood and iron sieved from the soil are directed to be reused as raw materials. Soil that is suitable for construction is used at Fortum’s own construction sites or reception centres for industrial waste. Clean soil is used as a fill material in restoration projects.

The more challenging and complex the restoration project, the better we are at it. Contact us to plan your solution together!
