Would the eutrophication of a lake be considered as point source or non-point source pollution? Why?

Answer 1

Eutrophication of a lake would generally be considered as a non-point source pollution. This is because the nutrients that contribute to eutrophication, such as phosphorus and nitrogen, typically come from a variety of diffuse sources such as agricultural runoff, urban runoff, and atmospheric deposition. These sources are not easily traced back to a single point of discharge, as is the case with point source pollution from sources like factories or sewage treatment plants.
