About the project
ICP Waters is a programme for monitoring of the effects of acid rain and air pollution on water and water courses.
Twenty countries (18 European countries, USA and Canada) participate and supply monitoring data to the programme's central database at NIVA. The monitoring data provide a basis for documenting effects of long-range transboundary air pollutants. An additional important programme activity is to contribute to quality control and harmonisation of monitoring methods. Results from annual assessments of surface water chemistry and biology demonstrate the success of international agreements to reduce emissions of pollutants.
The programme is financed by the Norwegian Environment Agency.
