V When comparing the data with those o f the classification by quality for use performed in the mid-1980's it should be borne in mind that there w ere not enough quality
observations for making the classification. This is true in particular o f the many lakes and rivers in Northern Finland. Therefore, some o f the w ater areas classified as
excellent or good in the classification of the mid-1980’s remained unclassified in the early 1990’s. Coastal waters were left entirely unclassified in the situation prevailing
in the early 1990's. The quality for use o f waters in areas affected by sewage continued to improve, but in areas dominated by agriculture there was a slight increase in
eutrophication in the early 1990's.
