Inland waters

Our inland waters, comprising lakes, rivers, wetlands, and groundwater, are vital for plants, animals, and human beings. 

The environmental challenges in such waters include watercourse regulation, acid rain, runoff of agricultural nutrients, contamination from environmental toxins, and the intrusion of foreign species. The Norwegian Environment Agency coordinates the work of establishing a cohesive, ecosystem-based water management. The goal is that the quality of all water shall be ecologically and chemically satisfactory.
