Oxygen depletion is a common problem in the hypolimnion of eutrophic lakes. Can also include support from municipalities and the private sectors, and highlights the action plan. These are used by the IJC to recommend new Areas of Concern and to determine if existing AOCs have been sufficiently cleaned up. If the input of a compound is higher than the output of the same compound it is an indication that the compound is accumulating in the system. A method to protect or restore biological diversity, beginning with an inventory of existing species and communities, and an analysis to select a restoration program that has the best chance for enhancing biodiversity.
Oligotrophic lakes have low productivity as a result.
Increasing phosphorus loadings to a water body may result in eutrophication. Phytoplankton are primary producers. A source of pollution that is distinct and identifiable such as an outfall pipe from an industrial plant. PAHs are produced when organic compounds are incinerated. The recommended plan and Implementation Annex constitute the Stage 2 Report.
