Climate changes, population growth, urbanization and the altered use of land, industrial and agricultural activities are some of the factors contributing to water pollution. Such a large proportion of the world's deposits of groundwater and surface water is now so polluted that it poses a threat to humans and aquatic organisms.

NIVA has wide ranging and multidisciplinary expertise in water related disciplines that enables us to identify contaminants in water and determine their consequences for nature and society. We develop, recommend and certify environmental technology.

Norway has committed itself to adhere to the stipulations of the EU Water Framework Directive. Among other things, this calls for good technological solutions for treating process and sewage water from industry, agriculture and households, as well as measures to restore polluted rivers, lakes and fjords.

NIVA activities include:

  • identifying pollution problems and their sources
  • assessing the consequences of pollution and issuing plans of action
  • implementing research and development projects
  • monitoring the effects of implemented measures
  • issuing plans for the protection and use of water deposits

1. Restoration of water deposits

  • Liming as a countermeasure to acidification
  • Initiatives to combat Gyrodactylus salaris in infected salmon streams and rivers
  • Restoration of overgrown stretches of streams and rivers
  • Establishment of artificial reefs to restore biodiversity

2. Industry and mining

  • Initiatives against leaching of polluted water from derelict pyrite mines
  • Initiatives against polluted sediments in harbours
  • Purification of injection water and produced water from the offshore industry
  • Disintegration of organic environmental contaminants and leachates from landfills

3. Municipal sewage and surface water

  • Map the flow of various substances to sewage and surface water drainage systems
  • Modelling the fate of various substances in treatment facilities and transport systems
  • Optimisation of water treatment processes
  • Measures against the effects  of climate change in the sewage sector
  • Treatment of water from land-based aquaculture
  • Development, testing and verification of water treatment technology
  • Measures against urban surface water runoff
  • Improvement of water treatment facilities in developing countries
