This discussion paper describes the different levels of eutrophic responses in the aquatic environment and, based on these levels, defines the criteria developed for identifying areas of pronounced eutrophication. These criteria have been developed using three cycles of existing Environmental Effects Monitoring (EEM) data. Levels of variation of data from exposure versus reference areas were associated to varying degrees of eutrophication based on relevant scientific literature. Presented criteria are intended to be used by mills to provide guidance for identifying sites with pronounced eutrophication.
