RIVER-WATER POLLUTION IN NORWAY: SOME REGIONAL ENVIRONMENTAL POLICY IMPLICATIONS*

This paper presents a systematic method of classifying water quality and identifies factors influencing the water quality of Norwegian rivers. Water quality and potential-pollution indices are developed for selected Norwegian drainage basins. The lowest-quality water is in the Mandals and Auli drainage areas, but the Glomma-Gudbrandsdal-Mjosa-Vorma system has the greatest pollution potential. Thus even in a waterrich country such as Norway, water policy is a major concern.
